Abstract
The utility model relates to an electric motor. The electric motor comprises a stator, a rotor and a retainer connected with the stator and the rotor; a shock absorber is arranged at the connecting part of the retainer and the stator; and the shock absorber adopts a hyperelastic body or a linear elastic body. The utility model provides an electric motor with low noise and small internal vibration.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of motor that is provided with vibration absorber between stator and retainer.
Background technology
The stator of existing motor is connected with rotor by retainer, there is following shortcoming in this kind version: because stator and retainer are rigidly connected, the vibrations of rotor are directly passed to stator, make stator vibrations big and noise is also big, and influence each other between stator and the rotor.The damping of existing motor all realizes by damping device is installed between motor casing and motor bed-plate, this kind version has just effectively been improved motor vibrations influence to external world, its noise is still very big, do not shake the difficult problem big, that noise is big and fundamentally solve motor interior, again and, influence each other between the rotor of motor and the stator, be unfavorable for the normal operation of motor.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of noise little, and the little motor of inner vibrations.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor, comprise stator, rotor, and the retainer that is used to connect described stator and rotor, the junction of described retainer and stator side is provided with vibration absorber.
Further, the side of the iron core of described stator is provided with at least two location holes, and described retainer is provided with respectively and described each position of positioning hole, shape, big or small corresponding cylinder, described each cylinder be inserted in respectively with its corresponding positioning hole in.
Further, described vibration absorber is a hyperelastic body, and this hyperelastic body is a thermoplastic elastic rubber.All be socketed with thermoplastic elastic rubber on described each cylinder, this thermoplastic elastic rubber is between stator and retainer, and the one side is against on the stator side, and its opposite side is against on the joint face of retainer and cylinder.
According to another embodiment of the present utility model, comprise that further described vibration absorber is a linear elastomer; Described linear elastomer is a Hookean spring; All be socketed with Hookean spring on described each cylinder, this Hookean spring is between stator and retainer, and the one side is against on the end face of location hole, and its opposite side is against on the joint face of retainer and cylinder.
The beneficial effects of the utility model: the utility model has solved the defective that exists in the background technology, between the stator retainer of motor and drive system casing, vibration absorber is set, the vibrations of drive system generation are just weakened widely by vibration absorber like this, it is very few to influence each other between stator and the drive system, also greatly reduces noise.
