Roller Guide Shoes For High Speed Elevators THY-GS-GL22
THY-GS-GL22 rolling guide shoe is also called roller guide shoe. Due to the use of rolling contact, hard rubber or inlaid rubber is installed on the outer circumference of the roller, and a damping spring is often installed between the guide wheel and the guide shoe frame, which can reduce the guide The frictional resistance between the shoe and the guide rail, save power, reduce vibration and noise, used in high-speed elevators 2m/s-5m/s. The initial pressure of the roller on the guide rail is adjusted by adjusting the compressed amount of the spring. The roller should not be skewed to the guide rail, and should contact the working surface of the guide rail evenly over the entire width of the rim. When the car is running, the three rollers should roll at the same time to keep the car running smoothly. Due to the external excitations such as the current machining geometric errors of the rollers and the guide rails, the installation joint deviations, and the friction and wear errors, the car produces horizontal and vertical vibration, torsion and other disturbances. The damping can obviously attenuate and dissipate such disturbances and play a vibration-absorbing and buffering role. The friction loss between the shoe lining and the guide rail is reduced, the vibration and noise during operation are reduced, the comfort of riding is improved, and the processing and installation requirements of the guide shoe are higher. The elastic support between the guide shoe frame and the guide rail can adaptively adjust the fit with the working surface according to the operating conditions, and can automatically compensate for the gap of the guide rail in the horizontal direction and on both sides. Rolling guide shoes generally do not need to install oil cups, do not need oil lubrication, and will not bring oil pollution to the car top and bottom pit, which is more environmentally friendly. It is Suitable for elevator guide rail width 10mm and 16mm.
