Description
Technical Field
The utility model relates to a generator part, in particular to a single-support generator rotor fixing device.
Background
The generator is distinguished according to the structural characteristics and can be divided into a single support and a double support. The single support generator is characterized in that the front end of the rotor is free without a bearing, and the rear end of the rotor is provided with a bearing and is fixedly arranged on a rear end cover of the generator through the bearing. The generator can not avoid receiving jolting in the transportation, and for single support generator, if the front end does not support fixedly, the generator rotor is easy to be because of the landing of jolting, breaks away from the rear end cover, probably causes the damage. To avoid this, the single support generator needs to be equipped with a rotor fixing device before transportation. The conventional rotor fixing device is used for connecting a rotor to a front end cover of a generator through a rotor fixing plate for fixing, but because the interfaces of a single-support generator are various, one interface of the conventional rotor fixing device corresponds to one state, and certain inconvenience is brought to management and use.

The utility model aims to solve the technical problem of providing a universal single-support generator rotor fixing device, which can achieve the aim of using the same rotor fixing device for different interfaces.
In order to solve the technical problems, the utility model provides the following technical scheme:
the utility model provides a universal single-support generator rotor fixing device,
fixing device is including rotor fixed plate, rotor fixing washer, bolt, it is provided with the through-hole to run through on the rotor fixed plate, the through-hole includes round hole and waist shape hole, the rotor fixed plate warp the round hole passes through the bolt fastening is on the generator front end cap, the rotor fixed plate warp waist shape hole passes through the bolt fastening is on the shaft coupling piece, be provided with between rotor fixed plate and the generator front end cap rotor fixing washer.
Preferably, a nut is arranged on the bolt, and the nut can prevent the bolt from loosening.
Preferably, the rotor fixing plates are arranged in at least two groups.
Preferably, the rotor fixing washers are provided in at least two sets.
Preferably, the minimum distance from the round hole on the rotor fixing plate to the waist-shaped hole is smaller than the minimum distance from the front end cover hole of the common interface to the coupler sheet hole.
Preferably, the rotor fixing plate is made of steel or plastic with strong toughness.
The utility model has the beneficial effects
The utility model can achieve the purpose of fixing the single-support generator rotors with different sizes and different interfaces by adjusting the number of the rotor fixing plates and the rotor fixing gaskets, and has the advantages of simple structure, low cost and strong universality.
