Control device of gateway

Abstract

The invention discloses a control device of a gateway, and belongs to the technical field of gateways, which comprises a reducer and a bearingless motor. The bearingless motor includes a motor statorand a motor rotor, wherein the output shaft of the bearingless motor and the input shaft of the reducer share the same shaft, the input shaft of the reducer extends from its flange oil seal to the outside, A motor rotor is sleeved and fixed at the middle section of the input shaft of the speed reducer, a motor stator is arranged on the motor rotor sleeve, the motor stator is fixed on the speed reducer and kept fixed, one end of the input shaft of the speed reducer is connected with a gateway which is driven through a speed reduction unit, and the other end of the input shaft of the speed reducer is idle. The device of the invention can overcome the coaxiality problem of the traditional device and thoroughly solve the abrasion problem of the coupling.

Description

technical field [0001] The invention belongs to the field of barrier gate control, and more particularly relates to a barrier gate control device. Background technique [0002] Most of the traditional barriers use bearing motors as the power source, and the motor shaft and the reducer or multi-stage reducer are connected by a coupling. Such a traditional structural form has the following disadvantages: [0003] (1) In the long-term use of the coupling, there is a problem that slow wear leads to the failure of the transmission from the motor to the reducer, and a large amount of worn iron cutting occurs in the coupling. [0004] (2) During assembly, it is difficult to maintain good coaxial consistency between the output shaft of the bearing motor and the input shaft of the reducer, and the reducer of the barrier gate control device with low coaxiality may cause wear of the oil seal due to vibration during long-term work Failure, which will further shorten the working life o...

AI Technical Summary

Problems solved by technology

[0003] (1) In the long-term use of the coupling, there is a problem that the slow wear leads to the failure of the transmission from the motor to the reducer, and a large amount of worn iron cutting occurs in the coupling

[0004] (2) During assembly, it is difficult to maintain good coaxial consistency between the output shaft of the bearing motor and the input shaft of the reducer, and the reducer of the barrier gate control device with low coaxiality may cause wear of the oil seal due to vibration during long-term work failure, which will further shorten the working life of the reducer

[0005] (3) The motor with bearings is noisy, which limits the application of barrier gates in low-noise or noise-limited environments

[0006] Therefore, it is necessary to develop a new type of control device for barrier gates to overcome the above defects of the prior art. It requires low noise, no problems of coaxiality in equipment and fast wear of couplings
