Abstract
The invention discloses an improved thrust bearing for a cross axle type universal coupling cross package. A plurality of oil grooves which are uniformly distributed in a radial mode along a peripheral direction are formed in the inner wall of the thrust bearing, and an annular oil groove is formed in the inner wall of the thrust bearing and is positioned at the periphery of the oil grooves which are uniformly distributed in the radial mode. The oil grooves which are uniformly distributed in the radial mode pass to the annular oil groove from the inner hole wall of the thrust bearing, and the inner hole of the thrust bearing is a waist-shaped hole. The structure of the improved thrust bearing is simple. A radial bearing rolling body uses a circular ring part between the annular oil groove and the periphery of the thrust bearing as a guide flange in the rotation process and does not pass through the annular oil groove and the oil grooves which are uniformly distributed in the radial mode, and a radial bearing continuously rotates. The inner hole of the thrust bearing is the waist-shaped hole, so that the thrust bearing can be positioned through a circular ring-shaped boss of the inner-side center of an end cover and can be prevented from rotating.
Description
Technical field
The invention belongs to coupling technical field, relate in particular to a kind of universal coupling with spider cross bag modified model thrust-bearing.
Background technique
Universal coupling with spider is a kind of the most frequently used coupling, utilizes the feature of its structure can make not at same axis or axis knuckle large or move axially larger diaxon isogonism speed continuous rotary, and transmitting torque and motion reliably.At present, be widely used in transmitting torque in the mechanical axis system of metallurgy, lifting, engineering transportation, mine, oil, boats and ships, coal, rubber, papermaking equipment and other Heavy duty maching industry.Traditional universal coupling with spider structure as shown in Figure 1, its cross bag comprises cross axle, radial bearing 1 is installed on the axle journal of cross axle, the axle head of cross axle is provided with thrust-bearing 2, thrust-bearing positions by the round ring boss 4 at end cap 3 centers, inner side, thrust-bearing bears the load that under working state, cross-member ends is transmitted, structure as shown in Figure 2, on its inwall, offer some and be along the circumferential direction radial equally distributed oil groove 5, oil groove storing lubricating grease, when work, provide sufficient anti-attrition lubricated, oil groove is passed straight through to the outer rim of thrust-bearing by inner hole wall, endoporus 6 is circular, as shown in Figure 1, the part outer ring of thrust-bearing, as the guiding rib of radial bearing, because oil groove passes straight through to outer by inner hole wall, makes radial bearing rolling element process oil groove in rotation process, causes radial bearing to rotate and occurs intermittently, from Fig. 1,3, thrust-bearing positions by the round ring boss at center inside end cap, but can not prevent that thrust-bearing from rotating, in the course of the work owing to existing frictional force to act on thrust bearing surface, cause that creeping appears in thrust-bearing in rotation process, crawl, cause that the outer wall surface that thrust-bearing contacts with end cap produces wearing and tearing, there is smalls, impurity, and cause that thrust-bearing gap increases, cause bearing vibration, precise decreasing.
Summary of the invention
For addressing the above problem, the object of this invention is to provide a kind of universal coupling with spider cross bag modified model thrust-bearing, it is simple in structure, reasonable in design, can make radial bearing rotate continuously, and prevents that thrust-bearing from rotating.
For achieving the above object, the present invention adopts following technological scheme:
A kind of universal coupling with spider cross bag modified model thrust-bearing, on its thrust-bearing inwall, offer some and be along the circumferential direction radial equally distributed oil groove, on thrust-bearing inwall, be provided with an annular oil groove, annular oil groove is positioned at the above-mentioned radial equally distributed oil groove outer rim that is, and some are radial equally distributed oil groove and pass to annular oil groove by thrust-bearing inner hole wall; The endoporus of thrust-bearing is waist shaped hole.
Described universal coupling with spider cross bag modified model thrust-bearing, the guiding rib that the annulus portion between its annular oil groove and thrust-bearing outer rim is radial bearing.
Owing to adopting technological scheme as above, the present invention has following superiority:
This universal coupling with spider cross bag modified model thrust-bearing, it is simple in structure, novelty reasonable in design, by arranging and be positioned at the annular oil groove that is radial equally distributed oil groove outer rim on thrust-bearing inwall, making the annulus portion that radial bearing rolling element be take between annular oil groove and thrust-bearing outer rim in rotation process is guiding rib, without annular oil groove and be radial equally distributed oil groove, radial bearing is rotated continuously; The endoporus of thrust-bearing is waist shaped hole, not only makes thrust-bearing pass through the round ring boss at center inside end cap and locates, and can prevent that thrust-bearing from rotating, and avoids causing that thrust-bearing gap increases, the problem of bearing vibration, precise decreasing.

Embodiment
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
As shown in Figure 4, this universal coupling with spider cross bag modified model thrust-bearing, on its thrust-bearing 2 inwalls, offer some and be along the circumferential direction radial equally distributed oil groove 5, on thrust-bearing inwall, be provided with an annular oil groove 7, annular oil groove is positioned at the above-mentioned radial equally distributed oil groove outer rim that is, and some are radial equally distributed oil groove and pass to annular oil groove by thrust-bearing inner hole wall; The endoporus 6 of thrust-bearing is waist shaped hole, and two ends are semicircle cambered surface, and middle part is parallel plane.
It is above-mentioned that to be radial equally distributed oil groove quantity be 6~8.
Described universal coupling with spider cross bag modified model thrust-bearing, the guiding rib that annulus portion between its annular oil groove and thrust-bearing outer rim is radial bearing, the position of annular oil groove arrange should meet radial bearing rolling element in rotation process through above-mentioned guiding rib, and without annular oil groove and be radial equally distributed oil groove.
Claims (2)
