Tyre CouplingA pin made of polyurethane and other elastic materials. It is placed in the flange holes of the two halves of a coupling. Transmission between the two halves of the coupling is achieved through the pin shaft. The structure is simple and easy to manufacture. The elastic components are easy to repair and replace without the need to move the two halves of the coupling. The material of the elastic components (pins) is usually nylon, which has a slight compensating ability for the offset of the two shafts.
However, due to the shearing effect on the elastic element during operation, its working reliability is poor. It is only suitable for low-speed transmission shaft systems with minimal requirements, not for high-reliability conditions. Keyway-type fixing is suitable for high-torque transmission. To prevent axial sliding, positioning and clamping screws are typically used for fixation.D-type holes are typically fixed. If the motor shaft is D-shaped, and if the locating screws cannot secure it, the coupling hole can be machined to match the size of the motor shaft's D-shaped hole. If using locating screws for fixation, there's no need to worry about slippage.
Tyre CouplingThe胀套fixed involves tightening the four locating screws on the coupling end face to clamp the sleeve. It is suitable for connecting and fixing some high-torque stepper motors and servo motors, such as telescopic diaphragm coupling, expanding sleeve梅花 coupling, and expanding sleeve bellows coupling, etc.
Tyre couplingThe pin on the shaft is in a state of shearing and compression during operation. The strength conditions involve calculating the shear strength of the elastic pin cross-section and the compressive strength between the wall of the pin hole and the wall of the pin hole. Due toTyre couplingFor cast iron material, weight ofkg, a significant amount of electrical energy was wasted during the water supply operation, affecting the unit's efficiency and increasing operating costs.
In actual production, sometimes the use of diameters less than12mm shaft coupling, which requires a non-standard shaft coupling design. The motor and output shaft are connected throughTire couplerConnection. The existing structure sometimes leads to failure in load transfer. The matched position of the motor and the half coupling.6mm diameter, 32mm length. No keyway on the shaft, unable to achieve keyed connection for torque transmission.
In compliance with the motor assembly requirements, a transition fit is used between the motor and the half coupling bore. Torque is primarily transmitted by two fixed screws mounted on the half coupling. The material of the elastic element (pin) is generally nylon, offering slight compensation for the offset of the two shafts. The elastic component is sheared during operation, resulting in poor operational reliability. It is only suitable for low-speed drive shaft systems with minimal requirements for reliability, not for high-reliability operating conditions.
