Bucket-wheel speed reducer having buffering function

Abstract

The invention provides a bucket-wheel speed reducer having the buffering function. The bucket-wheel speed reducer having the buffering function comprises a motor, a coupler, a first transmission shaft, a gear reducer connected with the first transmission shaft, an output shaft, a first planet transmission shaft, a planet gear, a second planet transmission shaft and a transmission bearing pedestal. One end of a buffering plate is connected to the gear reducer. The other end of the buffering plate is connected with a buffer device through a hinge pin. The lower end of the buffer device is connected with a base through a hinge pin. The outer portion of the gear reducer is connected with an oil feeder. The base is connected with a field. The bucket-wheel speed reducer having the buffering function is compact in structure, stable in operation, high in transmission efficiency and high in lubrication performance, the gear damage degree and the bearing damage degree are remarkably reduced, and the service life of a unit can be prolonged.

Description

technical field [0001] The invention relates to a deceleration device for equipment operation, in particular to a bucket wheel deceleration device with buffer force. Background technique [0002] Bucket wheel reclaimer is a large key equipment for mining flux ore and blended ore. Due to the unreasonable structure of the existing bucket wheel reducer, failures often occur. For example, the gears and bearings of the bucket wheel reducer are often broken; That is, the motor, reducer, coupler, etc. are all disassembled, resulting in a heavy workload and taking up to 12 hours. The defects of the reducer are often manifested in the following situations: [0003] (1) The reducer has a huge structure and consists of two parts: the active bevel gearbox and the planetary reducer. The planetary reducer is composed of two-stage planetary wheels, the transmission method is complicated, the transmission efficiency is low, the space occupied is large, the load capacity is large, and the...

AI Technical Summary

Problems solved by technology

Its planetary reducer is composed of two-stage planetary gears, the transmission method is complex, the transmission efficiency is low, the space occupied is large, the load capacity is large, and the weight of the bucket wheel transmission is increased.

The weight of the bucket wheel on the ground is too large, and the center of rotation of the bucket wheel reclaimer is shifted due to unbalance, resulting in tipping

[0004] (2) There are many alignment points in the design connection, that is, the motor and the hydraulic coupling, the coupling and the reducer, the coupling and the angular tooth shaft, which makes it difficult to find the alignment, and there will be a certain relative displacement and deviation. Slanted, resulting in radial runout and axial displacement, causing equipment failure

[0005] (3) The lubrication of the bucket wheel reducer is oil-immersed lubrication. When the bucket wheel is at a low position, the driving gear of the reducer often breaks the bearing and gear because it cannot be fully lubricated by the oil.

However, replacing the bearings and gears of the reducer requires dismantling the huge reducer motor for maintenance, resulting in labor-intensive and time-consuming maintenance

[0006] (4) During the reclaiming operation of the bucket wheel hopper, with the change of the amount of material, the height of the material layer and the degree of bonding of the material, the torque borne by the bucket wheel mechanism is a process of pulsating change. The pulsating impact force It also acts on the deceleration mechanism, so the operation of the bleed air equipment will be unstable, and the impact force will be too large, which may even cause the equipment to overturn.
