Abstract
The utility model belongs to an external spline universal coupling. The utility model is characterized in that the dimensions of cavities of an involute spline shaft fork, a double end shaft fork and a single end shaft fork are all reduced by 2 mm to 2.5 mm, and the length of a cross axle is correspondingly shortened by 2 mm to 2.5 mm. Outer ends of deadeyes of the involute spline shaft fork, the double end shaft fork and the single end shaft fork are all provided with check ring grooves which are provided with circlips. A needle bearing of the utility model is not easy to loosen or fall off, and the utility model has long service life, increasing to 12-18 months from 3-6 months. The utility model is an ideal universal joint in high speed mechanical transmission with two different shafts.
Description
The utility model relates to the mechanical transmission universal joint, is the external splines universal joint that uses in the transmission of a kind of two disalignment high speed machines.
At present, the external splines universal joint that uses on the dry method eyeball synthetic fibre spinning equipment crimping machine of U.S.'s import is seen accompanying drawing 1, is by the involute splines yoke, and double end yoke, cross axle, single head yoke and needle bearing constitute.Needle bearing overcomes the outward thrust that the cross axle changing load produces needle bearing in the transmission of high speed disalignment by the frictional force of the magnitude of interference generation of its cylindrical and matching hole.This design is unreasonable, and needle bearing easily becomes flexible, comes off, and often causes universal joint to scrap, and working life is short, only is 3～6 months.
The purpose of this utility model is: for increasing the service life, provide a kind of external splines universal joint of practicality, to overcome the outward thrust that cross axle produces needle bearing in the high speed machine transmission, solve needle bearing and become flexible, come off, often cause universal joint to scrap problem.
The purpose of this utility model is achieved in that the utility model sees accompanying drawing 2, be by the involute splines yoke, double end yoke, cross axle, single head yoke, needle bearing constitutes, be equipped with circlip groove in involute splines yoke, double end yoke, each bearing hole outer end of single head yoke, be provided with circlip in the groove.
In order to keep universal joint boundary dimension constant, involute splines yoke, double end yoke, single head yoke cavity size are all dwindled 2～2.5mm, the also corresponding shortening 2～2.5mm of cross axle length.
This model utility compared with prior art has the following advantages: this model utility makes needle bearing be difficult for becoming flexible, coming off because of set up circlip in each bearing hole, and long service life extended to 12～18 months by original 3～6 months.
Be described further below in conjunction with accompanying drawing:
Fig. 1: former U.S. import external splines gimbal structure schematic representation.
Fig. 2: the utility model external splines gimbal structure schematic representation.
Among Fig. 2: involute splines yoke (1), double end yoke (2), single head yoke (4), its external shape size is with existing identical, its cavity size is dwindled 2～2.5mm, the also corresponding shortening 2～2.5mm of cross axle (3) length, so that needle bearing (5) supporting surface remains unchanged, needle bearing (5) is with existing identical.Be equipped with circlip groove in involute splines yoke (1), double end yoke (2), each bearing hole outer end of single head yoke (4), be provided with circlip (6) in the groove, circlip (6) has 8, all adopts spring steel material to constitute.
Claims (3)
1, a kind of external splines universal joint is to be made of involute splines yoke (1), double end yoke (2), cross axle (3), single head yoke (4), needle bearing (5).It is characterized in that: in involute splines yoke (1), double end yoke (2) and each bearing hole outer end of single head yoke (4) are equipped with circlip groove, are provided with circlip (6) in the groove.
2, external splines universal joint according to claim 1 is characterized in that: involute splines yoke (1), double end yoke (2), single head yoke (4) cavity size are all dwindled 2～2.5mm, the also corresponding shortening 2～2.5mm of cross axle (3) length.
3, external splines universal joint according to claim 1 is characterized in that: circlip (6) has 8.
