Abstract

A sectional composite bearing is slidably disposed in a bearing channel and includes a plurality of spaced composite bearing elements, each of which includes a sliding block slidably coupled to the bearing channel and a sliding bearing fixedly coupled to the sliding block. Thus, the sliding contact area is reduced, and the shaft and the bearing pipeline are conveniently connected in a matched manner.

Description

Sectional type composite bearing

Technical Field

The utility model relates to a bearing product technical field, especially a sectional type composite bearing.

Background

When the shaft passes through a longer bearing pipeline, the sliding contact area of the shaft and the bearing pipeline is larger, and the friction force and the resistance are larger, so that the matching connection of the shaft and the bearing pipeline is difficult to realize.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a reduce sliding contact area, be convenient for the sectional type composite bearing that axle and bearing pipe's cooperation is connected to solve above-mentioned problem.

A sectional type composite bearing is arranged in a bearing pipeline in a sliding mode and comprises a plurality of composite bearing pieces arranged at intervals, and each composite bearing piece comprises a sliding block and a sliding bearing, wherein the sliding block is in sliding connection with the corresponding bearing pipeline, and the sliding bearing is fixedly connected with the sliding block.

Furthermore, the sliding bearing is cylindrical, and a bearing hole is formed in the middle of the sliding bearing.

Further, the slider is integrally connected to one side of the sliding bearing.

Furthermore, a guide rail is arranged in the bearing pipeline along the length direction, and a sliding block which is connected with the guide rail in a sliding mode is arranged on one side, away from the sliding bearing, of the sliding block.

Furthermore, a plurality of stop blocks are arranged in the bearing pipeline at intervals in a protruding mode, each composite bearing piece is movably located between two adjacent stop blocks, a positioning notch is formed in the corner of the sliding block in a recessed mode, and the positioning notch can be movably abutted to the stop blocks.

Further, the width of the positioning notch is half of the width of the stop block.

Further, a lubricating layer is arranged on the inner side wall of the sliding bearing.

Furthermore, the two ends of the sliding bearing in the radial direction are respectively connected with a sliding block, and the two sliding blocks are both in sliding connection with the bearing pipeline.

Compared with the prior art, the utility model discloses a sectional type composite bearing sets up in a bearing pipeline with sliding, sectional type composite bearing includes the composite bearing spare that a plurality of intervals set up, each composite bearing spare including relative bearing pipeline sliding connection's slider and with slider fixed connection's slide bearing. Thus, the sliding contact area is reduced, and the shaft and the bearing pipeline are conveniently connected in a matched manner.

Drawings

Embodiments of the present invention are described below with reference to the accompanying drawings, in which:

fig. 1 is a schematic perspective view of a sectional type composite bearing according to the present invention.

Fig. 2 is an enlarged schematic view of a portion a in fig. 1.

Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1, the present invention provides a sectional type composite bearing slidably disposed in a bearing pipe 10, wherein a pipe orifice 11 is disposed in the middle of the bearing pipe 10 along a length direction, a guide rail 12 is disposed in the pipe orifice 11 along the length direction, and a plurality of stoppers 13 are disposed in the pipe orifice 11 at intervals.

The utility model provides a sectional type composite bearing includes that a plurality of intervals are located the composite bearing spare in mouth of pipe 11, each composite bearing spare including relative bearing pipe 10 sliding connection's slider 20 and with slider 20 fixed connection's columniform slide bearing 30.

In the present embodiment, the slider 20 is integrally connected to one side of the slide bearing 30.

Referring to fig. 2, a sliding block 21 slidably connected to the guide rail 12 is disposed on a side of the sliding block 20 away from the sliding bearing 30, a positioning notch 22 is recessed at a corner of the sliding block 20, and the positioning notch 22 is movably abutted to the stopper 13.

Each composite bearing member is movably located between two adjacent stops 13.

The sliding bearing 30 has a bearing hole 31 formed in the middle thereof.

The width of the positioning notch 22 is half of the width of the stop block 13, so that when two adjacent composite bearing pieces are matched with the stop block 13, the two adjacent composite bearing pieces are in seamless connection, and a shaft can conveniently enter the next composite bearing piece from one composite bearing piece.

The inner side wall of the sliding bearing 30 is provided with a lubricating layer, such as a copper layer, a graphite layer, etc.

In the present embodiment, the number of the guide rail 12 and the slider 21 is 2.

In another embodiment, the sliding bearings 30 are connected with the sliding blocks 20 at two ends in the radial direction, and both the sliding blocks 20 are slidably connected with the bearing pipe 10.

The outer shaft first enters the mouth 11 of the bearing tube 10 and partially extends into a bearing hole 31 of a sliding bearing 30, and since the friction and resistance between the sliding bearing 30 and the shaft are greater than the friction and resistance between the sliding block 20 and the guide rail 12, the composite bearing piece will move along with the shaft until the sliding block 20 abuts against the stop 13.

The shaft then slides forward relative to the slide bearing 30 through the slide bearing 30. After which the shaft is partially inserted into the next slide bearing 30 and the above-described action is repeated so that the shaft passes through the entire bearing tube 10.

Compared with the prior art, the utility model discloses a sectional type composite bearing sets up in a bearing pipeline 10 with sliding, sectional type composite bearing includes the composite bearing spare that a plurality of intervals set up, and each composite bearing spare includes relative bearing pipeline 10 sliding connection's slider 20 and slider 20 fixed connection's slide bearing 30. Thus, the sliding contact area is reduced, and the shaft and the bearing pipeline are conveniently connected in a matched manner.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
