Problems solved by technology

[0002] At present, the existing electronic steering gear includes a fixed seat, which is provided with a ball screw, and the ball screw fixed seat is slidingly connected. One end of the fixed seat is fixed with a servo motor, and the servo motor is fixed on the fixed seat. One end of the ball screw is connected by welding or bolts, so that when the servo motor starts up instantly, it is easy to cause the welding of the rotating shaft and the ball screw to break, which will cause damage to the equipment

Abstract

The invention discloses a steering gear with a buffer effect. The steering gear comprises a base, a motor and a ball screw. The base is provided with a base plate with a retainer plate at the end. The motor is fixed to the outer side surface of the retainer plate through a motor holder. The ball screw is arranged at the position, corresponding to a motor revolving shaft, in the retainer plate, and is connected with the motor revolving shaft through a coupler. The steering gear is simple in structure and skillful in design. As the flexible coupler has certain capacity of compensating relative deviation between two axes of the coupled two shafts, and particularly, the flexible coupler with metal elastic elements has good buffering and damping performance and high bearing capacity and is adaptable to occasions with high changes of speed and load and with high temperature or low temperature, separation of the motor shaft and the ball screw is avoided and maintenance is facilitated.

Description

technical field [0001] The invention relates to the field of steering gears, in particular to a steering gear with a buffer function. Background technique [0002] At present, the existing electronic steering gear includes a fixed seat, which is provided with a ball screw, and the ball screw fixed seat is slidingly connected. One end of the fixed seat is fixed with a servo motor, and the servo motor is fixed on the fixed seat. One end of the ball screw is connected by welding or bolts, so when the servo motor starts up instantly, it is easy to cause the welding of the rotating shaft and the ball screw to break, which will cause damage to the equipment. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an electronic steering gear, which can solve the problem that the steering gear and the ball screw are easy to break. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted b...
