Bearing hole reinforcing structure of parking space gearbox body

Abstract

The invention discloses a bearing hole reinforcing structure of a parking space gearbox body. The bearing hole reinforcing structure of the parking space gearbox body comprises a fastening sleeve arranged outside one side of the bearing hole of the gearbox body, wherein the inner wall of the fastening sleeve is of a variable-diameter convex cylinder cavity structure, and a first bearing, an anti-skid fixing ring and a second bearing are sleeved in the fastening sleeve in sequence; a boring hole is formed in the anti-skid fixing ring, a first straight hole is formed in the middle of the fastening sleeve, a second straight hole is formed in a circular waist ring, and the boring hole, the first straight hole and the second straight hole are connected through a first bolt; triangular wing plates are welded on the outer side wall of the fastening sleeve, fan-shaped plates are clamped between the triangular wing plates, and the fan-shaped plates are connected with the gearbox body through asecond bolt. According to the invention, a relatively stable layer-like tower-type pipe joint structure is formed through the fan-shaped plates, the triangular wing plates, the circular waist ring, the fastening sleeve and the anti-skid fixing ring, the precision is higher, the bearing hole reinforcing structure is beneficial to ensuring the centering rotation of an output shaft of the gearbox, the vibration caused by larger torque force and bearing friction damage can be born, and the operation stability of the gearbox can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of parking gearboxes, in particular to a bearing hole reinforcement structure of a parking gearbox body. Background technique [0002] The number of cars owned by Chinese urban residents keeps growing at a high speed, and the flat parking lot can no longer meet the demand. The three-dimensional parking space system has emerged in response to the trend. The three-dimensional parking space system can realize the lifting, translation or rotation of the vehicle and its panel, and a suitable driving mechanism is required to realize the above movements. The driving mechanism mainly includes a motor and a gearbox, and the performance and precision of the gearbox determine the operation stability and safety of the three-dimensional parking space system. [0003] The existing parking space gearbox body generally imitates the gearbox used in motor vehicles directly. Its input shaft and output shaft are driven by gear...

Problems solved by technology

[0004] Different from motor vehicles, the output shaft of the gearbox body in the parking space needs to bear a large torque force during the traction process, and the stability of the short-term use is better, but when the use time is too long, the wear resistance of the bearing is poor, resulting in damage to The support structure of the input and output shafts is unstable, which can cause eccentric rotation, large vibrations, and the risk of drive failure or even accidents

[0005] Therefore, the bearing hole of the gearbox body of the parking space needs to be specially reinforced, but because the three-dimensional parking space is still in the promotion and development stage, the prior art has not yet paid attention to this point
