Description

Technical Field

[0001] The utility model relates to a dismantling device, in particular to a dismantling device for a torque arm hollow shaft speed reducer integrated machine. Background Art

[0002] Hollow shaft reducer is a special type of reducer with the characteristics of hollow inner cavity. Its structure usually includes inner and outer shells, end covers, input and output shafts, planetary transmission mechanism, etc., and realizes its reduction function based on gear cutting action.

[0003] When the hollow shaft reducer fails and the torque arm hollow shaft reducer needs to be replaced, the hollow shaft reducer and the roller shaft should be separated. Generally speaking, the torque arm hollow shaft reducer is not easy to separate due to the large friction between the torque arm hollow shaft reducer and the roller shaft.

[0004] Traditional method: hang the hand chain hoist on the hanger above the reducer, tie the center of gravity of the reducer with a wire rope, hang it on the hook of the hand chain hoist, tighten the hoist. Use two crowbars to act on both sides of the reducer through the fulcrum at the same time. Separate the reducer from the drum shaft head. The effect is minimal, and more often two hammers are needed to evenly hit both sides of the reducer at the same time to slowly separate them. It is time-consuming and laborious. Utility Model Content

[0005] The purpose of the utility model is to provide a torque arm hollow shaft reducer integrated machine dismantling device in view of the prior art. The dismantling device tightens the center bolt to make the center bolt move in the opposite direction of the axis of the drum, thereby driving the torque arm hollow shaft reducer integrated machine to move backward, thereby releasing the friction between the torque arm hollow shaft reducer integrated machine and the axis of the drum, thereby facilitating the separation of the torque arm hollow shaft reducer integrated machine from the axis of the drum, which not only solves the problem of the difficulty in separating the hollow shaft reducer integrated machine from the drum shaft, but also improves the efficiency of the dismantling work, while saving manpower and costs.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a torque arm hollow shaft reducer integrated machine dismantling device, which includes a fixing screw 1, a carbon steel plate 2, a middle nut 3, a rubber pad 4, and a center bolt 5. The middle nut 3 is welded to the middle of one side of the carbon steel plate 2, and the center bolt 5 is threadedly connected to the center of the carbon steel plate 2 and the middle nut 3, and the rubber pad 4 is attached to the other side of the carbon steel plate 2, and a fixing screw 1 is provided on the outer side of the carbon steel plate 2.

[0007] Furthermore, a side steel plate hole 201 for installing the fixing screw 1 is opened on the side of the carbon steel plate 2, and a middle bolt hole 202 for installing the center bolt 5 is opened in the middle of the carbon steel plate 2.

[0008] Furthermore, one side of the carbon steel plate 2 provided with the rubber pad 4 is connected to a hollow shaft speed reducer 6 , and a roller shaft 7 is installed in the middle of the hollow shaft speed reducer 6 .

[0009] Furthermore, a bolt through hole with threaded teeth is provided at the end surface of the hollow shaft speed reducer 6, and the number of the fixing screw rods 1 is the same as the number of the bolt through holes.

[0010] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: the dismantling device tightens the center bolt to make the center bolt move in the opposite direction of the axis of the drum, thereby driving the torque arm hollow shaft reducer integrated machine to move backward, thereby releasing the friction between the torque arm hollow shaft reducer integrated machine and the axis of the drum, thereby facilitating the separation of the torque arm hollow shaft reducer integrated machine from the axis of the drum, which not only solves the problem of the difficulty in separating the hollow shaft reducer integrated machine from the drum shaft, but also improves the efficiency of the dismantling work, while saving manpower and costs.
