Abstract
The invention discloses a spline pair with a centering function. The spline pair comprises a spline shaft and a spline sleeve sleeved on the spline shaft. A first centering ring and a second centering ring are arranged on inner sides of two ends of the spline sleeve respectively, an annular groove used for inserting spline teeth of the spline sleeve is formed at the inner end of the first centering ring, the first centering ring is integrated with the spline sleeve, the second centering ring is fastened on the spline sleeve through screws, a sealing ring is arranged between the second centering ring and the spline sleeve, and 0.12-0.18mm clearances are formed between the first centering ring and the spline shaft as well as between the second centering ring and the spline shaft. The centering rings are arranged at two ends of the spline sleeve, so that the spline teeth portion in the spline pair only plays a role in transmitting torque, the centering rings function in centering the spline sleeve and the spline shaft, and the problems of low manufacturing precision of the small spline tooth portion, poor matching precision of the spline pair and vibration are solved.
Description
Technical field
The invention belongs to spline manufacturing technology field, especially relate to a kind of spline pair with centering function.
Background technique
At present, spline joint is divided into square profile of tooth spline and involute splines by its profile of tooth, and square profile of tooth spline is easy to process, and bearing capacity is high, and involute splines can self contering, and machining accuracy is high.But, small-sized spline pair below diameter 200mm is used when the high-speed, high precision in the connection of all lengths stroke or under load is moving to be connected, because structure is less, active length is large, machining accuracy is difficult to control, cause spline pair excesssive gap or too small, during spline pair work, vibrate acutely or slide and have some setbacks, in particular in the connection of large stroke time, the splined shaft length of spline pair is longer, weight is larger, and during spline pair work, vibration or clamping stagnation are more obvious than the connection for little stroke.
Summary of the invention
In order to solve, above-mentioned small-sized spline tooth of the prior art portion accuracy of manufacturing is low, spline pair quality of fit is poor, easily cause the problem of vibration or clamping stagnation, the object of this invention is to provide a kind of reasonable in design, the spline pair with centering function that using effect is good.
For achieving the above object, the present invention adopts following technological scheme:
A spline pair with centering function, it comprises splined shaft, is enclosed within the spline housing on splined shaft; Inner side, spline housing two ends is respectively arranged with the first centering ring, the second centering ring, the inner of the first centering ring is provided with the circular groove of the spline tooth for inserting spline housing, the first centering ring and spline housing are set to one, the second centering ring by screw fastening on spline housing, and between the second centering ring and spline housing, be provided with seal ring, between the first centering ring, the second centering ring and splined shaft, all have the gap of 0.12～0.18mm.
The described spline pair with centering function, the inner of its first centering ring is provided with chamfering.
The described spline pair with centering function, the sectional shape of its seal ring is identical with the key tooth sectional shape of spline housing.
Owing to adopting technological scheme as above, the present invention has following superiority:
This has the spline pair of centering function, it is simple in structure, novelty reasonable in design, be easy to processing, by centering ring being set at spline housing two ends, make the effect that in spline pair, transmitting torque only bears in spline tooth portion, and centering ring plays the centering function of spline housing and splined shaft, overcome the problem that small-sized spline tooth portion accuracy of manufacturing is low, spline pair quality of fit is poor, cause vibration; At spline pair, use after a small amount of wearing and tearing of a period of time, overall transmission accuracy can be substantially constant, and flute profile sealing has extended the working life of spline pair, and the spline pair with centering function is particularly useful in transmission system that high-speed, high precision works under load effect.

Embodiment
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
As shown in Fig. 1～7, this has the spline pair of centering function, and it comprises splined shaft 5, is enclosed within the spline housing 1 on splined shaft; Spline housing one end inner side is provided with the inner of the first centering ring 9, the first centering rings with spline tooth 8 contact position of spline housing are provided with circular groove 7, for slotting spline tooth, owing to limitting the first centering ring and spline housing and be set to one in space; Spline housing the other end inner side is provided with the second centering ring 3, the second centering ring is fastened on spline housing by screw 4, and between the second centering ring and spline housing, be provided with seal ring 2, between the first centering ring, the second centering ring and splined shaft, all there is the gap of 0.12～0.18mm, spline housing and splined shaft contact position, all through surperficial cure process, increase wear resistance and anti-extrusion ability.
The first above-mentioned centering ring 9 the inner be provided with chamfering 6, be convenient to the assembling of splined shaft.
The sectional shape of above-mentioned seal ring is identical with the key tooth sectional shape of spline housing, the inside of seal ring 2 extends in the key tooth of splined shaft 5, and the lubricating grease that can guarantee spline pair inside under working condition does not leak and external dust foreign material do not enter spline pair inside.
