Abstract
The utility model discloses an electronic steering gear which comprises a motor. A ball screw is arranged bellow the motor, a fixed seat is arranged on the ball screw, the rotating shaft of the motor is provided with a first belt wheel, a second belt wheel is arranged at one end, close to the rotating shaft, of the ball screw, and the first belt wheel and the second belt wheel are connected through a belt. The electric steering gear is simple in structure, and ingenious in design, cannot cause the tripping off of the motor shaft and the ball screw, and is convenient to maintain.
Description
Technical field
The utility model relates to the deflector field, particularly relates to a kind of electronic commutator.
Background technology
Present existing electronic commutator comprises permanent seat, permanent seat is provided with ball screw, ball screw permanent seat sliding block joint, one end of permanent seat is fixed with servomotor, servomotor is fixed on permanent seat, and the turning cylinder of motor directly is connected with an end of ball screw, like this when servomotor moment startup, easily cause the junction fracture of turning cylinder and ball screw, will cause like this damage of equipment.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of electronic commutator, can solve the problem of deflector and ball screw easy fracture.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of electronic commutator is provided, comprise motor, the below of motor is provided with ball screw, ball screw is provided with permanent seat, the turning cylinder of described motor is provided with the first belt wheel, and ball screw is provided with the second belt wheel near an end of turning cylinder, connects by belt between the first belt wheel and the second belt wheel.
According to the technical solution of the utility model, the major opposing side of permanent seat is " L " type.Belt-driving like this, belt has certain buffering leeway when starting suddenly, so just can not cause the disengagement of motor shaft and ball screw.
The beneficial effects of the utility model are: the utility model is simple in structure, designs ingeniously, can not cause motor shaft and ball screw to be thrown off, and easy to maintenance.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Disclosed all features in this specification sheets, or the step in disclosed all methods or process except mutually exclusive feature and/or step, all can make up by any way.
