Abstract

The utility model relates to a cross shaft type universal shaft coupling. The cross shaft type universal shaft coupling is suitable for the industries of steel rolling, hoist, etc. One retreat stopping tile pad is directly arranged between a spline shaft and a spline sleeve. In addition, a bearing opening in a shaft connecting head is positioned by adopting a clamping spring. The utility model has more reasonable and compact structure, larger transfer torque, and longer service life.

Description

Universal coupling with spider

The utility model relates to a kind of Hooks coupling universal coupling, is applicable to mechanical industries such as steel rolling, lifting.

The utility model patent that the patent No. is called " a kind of universal coupling with spider " for the ZL90203884.2 name discloses a kind of technological scheme of universal coupling with spider, and the deficiency that this technological scheme exists is: 1, structure owes compact; 2, owing to structural reason, the radial dimension of the bearing in splined shaft and the cross shaft coupling head is subjected to certain restriction, thereby has influenced transmitting torque and working life.

The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, provides that a kind of more reasonable structure compactness, transmitting torque are bigger, the universal coupling with spider of longer service life.

The purpose of this utility model realizes by following measure: a kind of universal coupling with spider, the telescopic transmission shaft two ends of being made up of splined shaft and spline housing have cross shaft coupling head respectively, one removable retaining watt pad is housed between the bottom convex shoulder of said splined shaft and the spline housing port, said removable retaining watt pad is made up of the two halves circular casing, connect with a hinge between said two sleeve pipes, have a convex edge and a groove on the said sleeve pipe periphery, one sheath is installed between said convex edge and the groove, a spring ring is installed on the said groove; Bearing hole collar extension end in the said cross shaft coupling head is provided with groove, on the said groove jump ring is installed.

Below in conjunction with embodiment the utility model is further described.

Fig. 1 is the utility model general structure sectional view.

In the utility model universal coupling with spider, the telescopic transmission shaft two ends of being made up of splined shaft 1 and spline housing 2 have cross

shaft coupling head

3,4 respectively, one removable retaining watt pad 7 is housed between the bottom convex shoulder 5 of splined shaft and the spline housing port 6, removable retaining watt pad is made up of the two halves circular casing, there is a hinge to connect (this structure is identical with dependency structure in the described prior art) between two sleeve pipes, have a groove 9 of a convex edge 8 on the sleeve pipe periphery, one sheath 10 is installed between convex edge 8 and the groove 9, and it adorns a spring ring 11 on the groove; When need are pulled down coupling, spring ring is moved, the sheath that slides then can take out the purpose of retaining watt pad to realize changeing.In addition, the bearing hole collar extension end in the shaft coupling head is provided with groove 12, and jump ring 13 is installed on the groove, in order to place restrictions on the play of bearing, has so just changed bolt structure of the prior art.

Compared with prior art, the utlity model has following advantage:

1, simpler on the structure, reasonable, compact:

2, adopted said structure after, in the situation of identical appearance size, the diameter of splined shaft Can design greatlyyer with the diameter of bearing in the cross shaft coupling head, thereby can improve transmitting torque, Reduced simultaneously because of the loosening maintenance that causes of primitive axis bonnet bolt and delayed work, increased the service life.

Claims

1, a kind of universal coupling with spider, the telescopic transmission shaft two ends of being made up of splined shaft and spline housing have cross shaft coupling head respectively, it is characterized in that:

(1) a removable retaining watt pad is housed between the bottom convex shoulder of said splined shaft and the spline housing port, said removable retaining watt pad is made up of the two halves circular casing, connect with a hinge between said two sleeve pipes, have a convex edge and a groove on the said sleeve pipe periphery, one sheath is installed between said convex edge and the groove, a spring ring is installed on the said groove;

(2) the bearing hole collar extension end in the said cross shaft coupling head is provided with groove, on the said groove jump ring is installed.
