Speed reducer fixing device for roll gang

Abstract

The invention provides a speed reducer fixing device for a roller gang, and belongs to the technical field of roller gang equipment of continuous machines. According to the speed reducer fixing devicefor the roller gang, the side face of a motor fixing chassis (4) is connected with a supporting beam (1), a motor fixing belt (6) is arranged on a speed reducer in a sleeving mode and is fixedly connected with a motor fixing disc (4), a speed reducer assembling base plate (7) is arranged at the lower end of a speed reducer body (2), the side face of a speed reducer fixing chassis (5) is connectedwith the supporting beam (1), and the speed reducer assembling base plate (7) is connected with the speed reducer fixing chassis (5). According to the speed reducer fixing device for the roller gang,fault points can be eliminated through the speed reducer body (horizontal speed reducer) fixing device, so that the overall stability of the speed reducer fixing device is improved, the dangers are reduced for workers, and the speed reducer fixing device has a positive effect on reducing the cost and improving the efficiency; and meanwhile, fixing device connecting bolts and connecting plates arenot needed, so that the strength is ensured, and fatigue fractures are prevented.

Description

technical field [0001] The invention belongs to the technical field of conveying roller table equipment for continuous casting machinery, and more specifically relates to a fixing device for a conveying roller table reducer. Background technique [0002] The slab produced by the existing continuous casting needs to be transported through the conveying roller table. The power source of the transportation is that the reducer drives the conveying roller to rotate, that is, the reducer is fixed on the reducer fixing device, and the motor drives the reducer to rotate, and then the conveying roller rotates. , the fixing device has the following defects during use: 1. The fixing device provides a fixed point for the reducer and the motor. If the fixed point cannot function normally, the reducer and the motor will rotate around the conveyor roller shaft after losing the fixed point. The power cannot be normally transmitted to the billet to make it move forward. This is a point of fa...

[0002] The slab produced by the existing continuous casting needs to be transported through the conveying roller table. The power source of the transportation is that the reducer drives the conveying roller to rotate, that is, the reducer is fixed on the reducer fixing device, and the motor drives the reducer to rotate, and then the conveying roller rotates. , the fixing device has the following defects during use: 1. The fixing device provides a fixed point for the reducer and the motor. If the fixed point cannot function normally, the reducer and the motor will rotate around the conveyor roller shaft after losing the fixed point. The power cannot be normally transmitted to the billet to make it move forward. This is a point of failure in production; 2. The fixing device is too simple, and the reducer is only connected by a connecting plate and a fixing bolt, and the connecting bolt and the connecting plate of the reducer Fatigue fractures often occur; 3. The fixing device is located under the reducer, the space is narrow, the maintenance is difficult and time-consuming, and the maintenance frequency is high; 4. Since the reducer and the motor have only one fixed point, and the fixed The point is not on the center of gravity of the reducer and the motor as a whole, resulting in poor overall stability of the reducer and the motor; 5. Since the location of the fixing device is not conducive to the maintenance of the maintenance workers, there are hidden dangers to the safety of personnel in regular maintenance

Therefore, the existing structure cannot meet the demand
