Description

Technical Field

[0001] The utility model relates to the technical field of steering gear rotation, in particular to a steering gear rotation system. Background Art

[0002] Flatbed transport machinery is an important transport machinery for industrial plant transportation, especially suitable for the transportation of large parts. The steering wheel drive device is the main component of the flatbed transport machinery and is the driving device of the flatbed transport machinery. The coordinated operation of multiple steering wheel drive devices can realize the movement of the flatbed transport machinery.

[0003] In the prior art, the motor drives a multi-stage planetary reducer, and a pair of cylindrical gears are meshed externally for deceleration. The rotary motor rotates around the rotation center, and the transmission ratio does not meet the requirements. The volume is large and the weight is heavy. Since the rotary fixed seat rotates during the rotation process, and the rotary motor is fixed on the rotary fixed seat, the rotary motor will rotate around the rotation center. Since the cylindrical external meshing is limited by the minimum number of teeth, the transmission ratio of the first meshing does not meet the use requirements, and the volume of the multi-stage transmission becomes even larger.

[0004] The steering of a flatbed truck depends on the steering wheels to deflect the corresponding angle according to the steering requirements. Since the steering resistance torque of the steering wheel is large and the steering speed is relatively slow, the current technology is that the motor drives the geared rotator through the planetary reducer, and the rotator drives the steering gear rotating device to achieve steering. Due to the multi-stage reduction mechanism used, the volume is large and the weight is heavy, and the transmission ratio is difficult to meet the steering requirements. Now a steering gear rotation system is invented that uses an electric motor with a planetary reducer to drive a slewing support with a worm gear, thereby driving the steering gear rotating mechanism to achieve steering and solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a steering gear rotation system, which solves the problems raised in the above background technology.

[0007] (II) Technical solution

[0008] To achieve the above purpose, the utility model is implemented through the following technical scheme: a steering gear rotation system, including a rotation motor, a rotation reducer and an outer rotation sleeve, a transition connection seat is installed on the top of the rotation reducer, a worm gear reducer is installed on the top of the transition connection seat through a fastener, the worm gear reducer is divided into a fixed part of the worm gear reducer and a moving part of the worm gear reducer, and the inner part of the outer rotation sleeve is fixedly connected to the inner rotation sleeve by a key.

[0009] Optionally, the rotary motor is mounted on the bottom of the rotary reducer via fasteners, and the length of the worm gear reducer is greater than the diameter of the outer rotary sleeve.

[0010] Optionally, the outer rotating sleeve part and the inner rotating sleeve part have the same center, and the diameter of the outer rotating sleeve part is greater than the diameter of the inner rotating sleeve part.

[0011] Optionally, the positions of the outer rotary sleeve fitting and the inner rotary sleeve fitting are both higher than the position of the rotary motor.

[0012] Optionally, the rotary motor, the rotary reducer and the worm gear reducer are all electrically connected to an external power source via wires.

[0013] Optionally, the fixed part of the worm gear reducer is fixedly connected to the vehicle frame via fasteners, and the moving part of the worm gear reducer is fixedly connected to the outer rotating sleeve via fasteners.

[0014] (III) Beneficial effects

[0015] The utility model provides a steering gear rotation system, which has the following beneficial effects:

[0016] 1. The steering gear slewing system has the advantages of small size, light weight, large transmission ratio, the slewing motor does not rotate with the rotation of the steering gear, and convenient wiring harness arrangement, through the arrangement of the slewing motor, slewing reducer, transition connection seat and worm gear reducer. The motor drives the planetary reducer with a relatively small reduction ratio to drive the worm gear slewing support. Since the transmission ratio of the worm gear reducer is very large and the motor has a high speed, the entire transmission system has a relatively small size, light weight, and a large output torque. Due to the self-locking performance of the worm gear reducer, the steering motor can be without a brake, thereby achieving the purpose of improving practicality.

[0017] 2. The steering gear slewing system, through the arrangement of the outer slewing sleeve fitting, the inner slewing sleeve fitting and the key, has a steering motor installed together with a steering slewing support, and does not rotate with the rotation of the steering wheel, thereby avoiding the disadvantage that the wiring harness moves with the rotation of the steering gear. The motor with a planetary reducer is used to drive the slewing support with a worm gear, thereby driving the steering gear slewing mechanism to realize steering, thereby achieving the purpose of improving practicality.
