What are the four major categories of clutches in the country at present? Xiaobian categorizes them for you and hopes to help you! The clutch is divided into an electromagnetic clutch, a magnetic powder clutch, a friction clutch, and a fluid coupling. Mechanical parts that can engage or disengage the driving shaft and the driven shaft at any time according to work requirements. It can be used to control the start, stop, speed change and reversal of the drive system of the machine. There are many types of clutches, which can be divided into: ① Controlled clutch. The operating methods are mechanical, electromagnetic, pneumatic, and hydraulic, such as embedded clutches (transmitting torque through the fit of teeth, teeth, or keys), friction clutches (transmitting torque using friction), and air flexible clutches (using Compressed air tires expand and contract to manipulate the clutches that are engaged or disengaged by the friction parts), electromagnetic slip clutches (generating magnetic force with exciting current to transmit torque), and magnetic powder clutches (magnetizing magnetic powder with exciting coils to form magnetic powder chains to transmit torque). ② Automatic clutch. Use simple mechanical methods to automatically complete the engagement or disengagement action. It is also divided into safety clutches (the transmission shaft can be automatically separated when the transmission torque reaches a certain value to prevent overload and prevent important parts of the machine from being damaged), centrifugal clutches (when the drive shaft When the speed reaches a certain value, due to the effect of centrifugal force, the transmission shafts can be self-coupled or separated after exceeding a certain speed), directional clutches (also known as overrunning clutches, using ratchet-pawl engagement or rollers, wedges The wedging action transmits motion or torque in one direction. When the driving shaft is reversed or the speed is lower than the driven shaft, the clutch is automatically released).

In normal operation, the magnetic powder brake generates slip power due to the slip speed. Slip power will increase the temperature of bearings, magnetic powder and other components of magnetic powder brakes. In order to prevent the production temperature from being too high, the rated continuous sliding power is set for each model. Users are required to observe this rating and use it within the rated range. The magnetic powder brake continuously generates a certain amount of heat. In addition to the necessary high heat-resistant magnetic powder and other materials, a good heat dissipation method is also necessary. Air cooling is the main cooling method of Tianji magnetic powder brake. There are various other cooling methods depending on factors such as manufacturer, model and use environment. The magnetic powder brake needs to be controlled within the allowed temperature. More types and specifications of products Selection, quotation, order welcome to consult!!!

Before using the magnetic powder brake transmission equipment, it must be properly connected and installed. Recently, many users have consulted how to properly connect the magnetic powder brake and printing press equipment. It is normal for users who come into contact with the magnetic powder brake to encounter this problem. The Tianji Transmission manufacturer introduces the wiring problem of the magnetic powder brake and the equipment to be connected. The wiring of magnetic powder brake is very simple. It only needs to connect two wires to DC24V DC power supply, regardless of positive and negative poles. If there is no 24V DC plug, you can buy a transformer to use it, which is safe and practical. Similarly, the magnetic powder brake is generally connected with a tension controller and a tension sensor to detect the tension of steel belts, paper, steel belts and other materials. It is mostly used in the unwinding and rewinding industries. The combination of magnetic powder brake, tension sensor and tension controller can realize real-time detection of the tension of the printing press paper and control of the magnetic powder brake torque, which greatly improves the production efficiency of the rewinding and unwinding industry. Before selecting the Tianji Transmission brand magnetic powder brake, the online customer service will inform the user of the method of use in advance and provide a selection plan for free, so that users can use it with peace of mind.

There are many names for the inflatable shaft, and the working principle is the same. The inflatable shaft and inflatable sleeve are extremely convenient and fast to use. You only need to bring your own air source. The air pressure is controlled within the range of 6-8kg / cm2. For parts (such as round paper tubes), as long as the air gun is inflated against the air nozzle on the inflation shaft, it can be completed. When holding against external parts (such as round paper tubes), you need to relax the paper when you unload the paper. It can be removed by pressing the sliding outer part (such as a round paper tube) on the air nozzle. Inflatable shaft specifications: 1-inch, 1.5-inch, 2-inch, 2.5-inch, 3-inch, 6-inch, 8-inch, 10-inch, 12-inch, inflatable sleeves, etc., can be processed to produce different specifications of inflatable axis.

1. Safety hood or other safety measures with good ventilation. 2. The air pressure disc brake must be used within the allowable connection and braking workload. If it is used in excess of the allowable connection braking load during operation, it will cause heat increase, the friction surface will become red and heat, and excessive heat may cause fire, and it will directly affect the performance of the brake. Used within connected brakes. 3. Do not increase the number of rotations without permission. If it is used in excess of the allowable number of rotations, the vibration will increase, and depending on the occasion, it may be damaged or scattered, and may be in a very dangerous state. Be sure to use the protective cover for a few rotations. 4. The friction plate used must not be stained with water or grease, otherwise it will affect the torque or work performance. 5. Before installing the air pressure disc brake, please confirm the surrounding environment. If it is exposed to moisture, oil, dust, or vibration and shock, and high humidity, it will directly affect the life and performance of the pneumatic actuator .

TJ-POC type magnetic powder clutch is used for cloth inspection. It is rewinding type to check the quality of cloth or film. A TJ-POC type magnetic powder clutch is installed between the reduction motor and the reel, and its role is to control the torque of the reel. The tension of the cloth or the film reel is fed back by the tension detector, and the torque of the magnetic powder clutch is controlled by the tension controller to achieve the balance of the cloth or the film's reel. The main purposes of installing TJ-POC open magnetic powder clutch in textile cloth inspection machine are as follows: 1. Change the unwinding and winding action by changing the direction of the material. 2. The tension is constant when unwinding, and it is achieved by controlling the tapered tension when winding. Changing the external circuit can change the above action. The textile inspection machine is suitable for TJ-POC type magnetic powder clutch tension between 100-150N, and the linear speed is recommended to be 50-200 m / min. In addition, it should be noted that the magnetic powder clutch on the unwinding side must be fixed on the side of the reduction motor, so it is recommended to use a motor with a brake, or a reduction motor that can rotate continuously at 15 rpm (within the allowed slip rate Within range) TJ-POC magnetic powder clutch of Tianji Transmission is specially used for cloth inspection. It is a brake clutch specially designed for cloth inspection.

Dry-type electromagnetic brakes are currently selected automatic actuators. The brakes are realized by electromagnetic effects. They can be divided into electromagnetic friction, electromagnetic powder, and eddy current. Among these non-formal electromagnetic brakes, the electromagnetic friction type is the most widely used. Dry-type electromagnetic brake is mainly composed of brake parts, brake frame and other parts. It is an ideal automatic execution element, which plays the role of power transmission and motion control in the mechanical transmission system. It has the advantages of fast response, simple installation and operation, compact structure, wear resistance, and easy remote control. The selection of dry electromagnetic brake model specifications is determined by the structure and working requirements of the machine. The performance of the friction material used in the brake directly affects the braking process, and the main factors affecting the friction material are the operating temperature and temperature rise rate. Therefore, the friction material needs to have a high and stable friction coefficient and good abrasion resistance.
