Description
[technical field]
The present invention relates to a kind of motor and with the air compressor machine of the motor, in particular to the shaft of a kind of motor and crankshaft
Connection structure.
[background technique]
Motor generally includes shaft and crankshaft, and crankshaft is fixed on shaft, and the component being transmitted is also connected on crankshaft, and shaft turns
Movable property gives birth to driving torque, to drive subsidiary component movement by crankshaft.Motor widely applies to mechanical transmission field,
Existing crankshaft and shaft are connected and fixed structure are as follows: mill a plane in shaft, lock crankshaft eccentric with a screw and turning
On axis, since the lock power of crankshaft and shaft is often short of when motor is using a period of time or larger load, the crankshaft in rotation
Connection between shaft is easy to loosen, and then leads to the Joint failure between crankshaft and shaft, and thoroughly idle running occurs in shaft,
Cannot be again with dynamic crankshaft and subsidiary component rotation, while also will cause screw and damaging axis friction.Therefore, the design provides
A kind of new scheme.
[summary of the invention]
The problem to be solved by the invention is to provide fixations dual between a kind of crankshaft and shaft, the pneumatics for inhibiting positioning to fail
Machine.

Preferably, the positioning port is equipped with inner bottom surface, and the end of the positioning column presses on the inner bottom surface.
Preferably, the positioning port has medial surface, and the medial surface is around the positioning column.It is designed in this way, medial surface
Can be preferably around positioning column be limited, it can be in the direction upper limit positioning column parallel with the axis of shaft and in shaft
Circumferential upper limit positioning column.
Preferably, the positioning port has medial surface, and the medial surface includes positioned at positioning column two opposite sides and in shaft
Circumferential direction on opposite first side and second side, the positioning column and first side partly overlap in the circumferential direction of shaft,
The positioning column mutually recline with first side or there is gap and separately, the circumferential direction of the positioning column and second side in shaft
On partly overlap, the positioning column mutually recline with second side or there is gap and separately.The technical program includes a variety of feelings
Shape, wherein when the positioning column mutually reclines respectively with first side, second side, may make positioning column in the circumferential direction of shaft
It is clamped by first side and second side, positioning column is promoted to keep stablizing in the circumferential direction of shaft, not loosen；When the positioning column
All there is gap with first side, second side, even if positioning column is loosened relative to shaft, but the space loosened only leans on two
The gap of side generates, so that the space loosened is very small, positioning port still more can closely limit positioning column；When described fixed
Position column mutually reclines with one of first side, second side and has gap with another one, is situated between to the locating effect of positioning column
Between first two scheme (scheme that the scheme of clamping, positioning column two sides have gap), repeat no more.
Preferably, the motor further includes fixed column, and the fixed column is fixed on through-hole, and the fixed column is supported towards shaft
Press the positioning column.It is designed in this way, the fixed stability of positioning column can be obviously improved, prevent positioning column from loosening.
Preferably, the fixed column, which is spirally connected, is fixed on the through-hole and is coaxially disposed with the positioning column.
