Abstract
The utility model relates to a kind of end caps with lubrication slot structure of center-rotary joint, including end cap, rotating shaft, revolving body, it is characterized in that, lubrication groove is laid in the end cap plane, reduce and revolving body planar friction area, the frictional force generated when revolution is effectively reduced and receives dirt, the end cap is assemblied on rotating shaft and end cap by screw and revolution axis connection, the revolving body.The utility model compared with prior art, has simple and compact for structure, and processing and manufacturing is easy, and lubrication reduces friction area and receives dirty effect, so that the service life of end seal under center-rotary joint is improved 3 times or more, greatly improves reliability.
Description
Technical field
The utility model belongs to engineering machinery field, the end with lubrication slot structure of especially a kind of center-rotary joint
Lid.
Background technique
Currently, the center-rotary joint used on the center-rotary joint that engineering machinery uses, especially wheel excavator,
When being mounted on the vehicle frame of lower running body, by endcap support revolving body, when rotated, the revolution of fixed end cap and rotation
Between body, a rubbing surface is formed.Due to being exactly ground surface below swivel joint, silt dust is easy to be attached to central revolution
On connector, particle, dust are entered between end cap and the rubbing surface of revolving body, cause inordinate wear, and enter eventually into revolution
It at the sealing element of axis, causes sealing element to damage and leads to oil leak, failure, reduce reliability, this is the master of center-rotary joint
Want one of failure mode.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and compact for structure, there is lubrication to reduce friction area and receive dirty
Effect makes the service life of end seal under center-rotary joint improve 3 times or more, greatly improves the end of the lubrication slot structure of reliability
Lid.
The technical solution taken in order to achieve the above objectives is as follows:
1, the end cap with lubrication slot structure of a kind of center-rotary joint, including end cap, rotating shaft, revolving body, it is special
Sign is, lubrication groove is laid in the end cap plane, by screw and revolution axis connection, described returns the end cap
Swivel is assemblied on rotating shaft and end cap.
2, a kind of end cap with lubrication slot structure of center-rotary joint as described in technical solution 1, wherein the end
Lubrication groove depth >=the 0.5mm covered, shape is V-arrangement or U-shaped, and lubricating grease is smeared on lubrication groove.
The utility model compared with prior art, have it is simple and compact for structure, processing and manufacturing be easy, lubrication reduce rubbing surface
Product and dirty effect of receiving, make the service life of end seal under center-rotary joint improve 3 times or more, greatly improve reliability.
Detailed description of the invention:
Fig. 1 is the overall structure main view of the utility model,
Fig. 2 is A-A cross-sectional view in Fig. 1 of the utility model,
Fig. 3 is the end cap part main view of the utility model,
Fig. 4 is the end cap part top view of the utility model,
Fig. 5 is the partial enlarged view of the utility model,
Fig. 6 is the revolving body main view of the utility model,
Fig. 7 is the rotating shaft main view of the utility model.
In FIG. 1 to FIG. 7, end cap (1), rotating shaft (2), revolving body (3), screw (4), lubrication groove (5).
Specific embodiment:
The utility model is further described with reference to the accompanying drawings and examples:
Shown in referring to Figure 1 to Figure 7, a kind of end cap with lubrication slot structure of center-rotary joint, including end cap, revolution
Axis, revolving body, wherein be laid with lubrication groove 5, reduction and 3 planar friction area of revolving body in 1 plane of end cap, have
The frictional force and dirt of receiving, the end cap 1 generated when effect reduction revolution is connect by screw 4 with rotating shaft 2, the revolving body
3 are assemblied on rotating shaft 2 and end cap 1.
5 depth of lubrication groove >=0.5mm on the end cap 1, shape are V-arrangement or U-shaped or other shapes, and in lubrication groove
Lubricating grease is smeared on 5.
When the center-rotary joint is mounted on digging machine vehicle frame, revolving body 3 is support by end cap 1, when rotated, Gu
Between fixed end cap 1 and the revolving body 3 of rotation, a rubbing surface is formed, the lubrication groove 5 on end cap 1 and wherein filled at this time
Lubricating grease can play the role of reducing friction area and frictional force.Due to being exactly ground surface, silt dust below swivel joint
It is easy to be attached on center-rotary joint, when particle, dust enter between end cap 1 and the rubbing surface of revolving body 3, in center
Swivel joint is contained on lubrication groove 5 after being grinded up when rotating, and the service life of end seal under center-rotary joint is made to improve 3 times
More than, greatly improve reliability.
Claims (2)
