Abstract
The utility model discloses a transmission shaft, in particular to an input shaft for a worm gear box, which comprises a shaft body and a shaft end and is characterized in that the shaft end is a conical body, the underside of the conical body is a plane, and the inclination of the conical body ranges from 1 DEG to 7 DEG. The utility model can realize gapless fit so that a whole product stably runs, reduces noise, prolongs service life and enhances economic benefit enhancement. The utility model can be widely applied to various worm gear box occasions.
Description
Technical field
The utility model relates to a kind of transmission shaft, specifically is meant a kind of input shaft of Worm gear case.
Technical background
Worm gear case is a kind of machinery commonly used, and output shaft wherein Worm gear case and miscellaneous equipment especially carries out the pass based part of power transmission, and its quality will directly determine working life, efficient of Worm gear case etc.Output shaft end is and the interface position of other mechanical parts that design commonly used is that cylindrical body adds keyway arrangements, be Spielpassung, and the operating conditions of Worm gear case must be forward and reverse running.Time one is long, and that certainly will cause key and keyway wastes damage fast, influence working life, and when connecting, because the difficult aligning of keyway has increased assembling difficulty.In case the assembling gapped existence in back in use, then continuous noise can occur, influence stability.
The model utility content
The utility model has proposed a kind of effective solution of the above problems at deficiency of the prior art.
The utility model is achieved by following technical proposals:
A kind of Worm gear case input shaft, it comprises axis body, axle head, it is characterized in that axle head is a cone, is a plane below the cone.
As preferably, above-mentioned a kind of Worm gear case input shaft, the oblique angle of described cone are 1 °～7 °.As better selection, the oblique angle of described cone is 2 °～5 °.
In the utility model, shaft end is designed to conical structure, have better quality of fit, make assembling become easy, a plane below the cone replaces key to cooperate the transmitting torque effect with keyway, and the component belt pulley is axially fastened by outside thread and nut, realizes that no gap cooperates.
The beneficial effects of the utility model: can realize not having the gap and cooperate, make the entire product running steadily, reduce noise, increase the service life, increase economic efficiency.
Description of drawings

Fig. 2 A-A is to the view sectional drawing
1, axle head 2, plane 3, outside thread 4, the oblique angle 5 of cone, axis body
Embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is explained:
With reference to accompanying drawing 1, make the input shaft of a Worm gear case, axis body 5 is the cylindrical body of a routine.With reference to accompanying drawing 2, plane 2 of making below axle head 1, the oblique angle of cone is 2 °.Outside thread 3 making routinely of end when the input shaft of Worm gear case and component belt pulley are axially fastened by outside thread 3 and nut, realizes that no gap cooperates, and it is steady that entire product is turned round.Reduce noise, increase the service life, increase economic efficiency.
