Abstract

The utility model discloses an adjustable sliding bearing device which comprises a shaft sleeve and a disc arranged outside the shaft sleeve. A sliding bearing is sleeved outside the shaft sleeve and comprises at least two bearing split bodies. Each bearing split body comprises a bearing split body annular ring wall, and an arc surface matched with the radian of the outer lateral wall of the shaft sleeve is arranged on one side of the bearing split body annular ring wall close to the shaft sleeve. The bearing split body annular ring walls of the bearing split bodies form a bearing annular body arranged outside the shaft sleeve together. A bearing fixing plate is arranged on the side of each bearing split body annular ring wall far away from the shaft sleeve and is adjustably arranged on the disc. The original integral sliding bearing is changed into the sliding bearing composed of a plurality of bearing split bodies which can form a circle and are fixed on the disc. When the sliding bearing is abraded, clearance caused by the abrasion can be reduced only by moving the bearing split bodies to the center of the shaft sleeve. By means of the structure, the sliding bearing can be made full use, maintenance cost is greatly reduced, and maintenance time is effectively shortened.

Description

A kind of adjustable sliding bearing means

Technical field

The utility model relates to the stirring technique field, is specifically related to a kind of adjustable sliding bearing means.

Background technique

At present, in stirring system, because axial length in the tank can change along with the size of equipment, when equipment is larger, because of cantilever longer, can normally move in order to ensure equipment, generally be in middle part or the bottom of stirring shaft sliding bearing to be set, be arranged at the intermediate bearing that cries at middle part, the bottom be base bearing, be arranged in the sliding bearing of intermediate bearing, because of the operation of equipment, sliding bearing can need regularly replace because of wearing and tearing, mainly be that the swing when causing stirring shaft to move increases because after returning wearing and tearing after the long-term use of sliding bearing, cause the gap between sliding bearing and stirring shaft or the stirring shaft sheath to increase, the phenomenons such as vibration equipment or shake appear easily, cause equipment normally not move, can only regularly replace sliding bearing, can not be more abundant but the wall thickness of sliding bearing is still thicker, caused larger waste, changed simultaneously whole sliding bearing and also need longer engineering time.

Summary of the invention

The purpose of this utility model is: for the deficiencies in the prior art, the utility model provide a kind of easy to adjust, can effectively increase the plain bearing arrangement adjustable sliding bearing means in working life, sliding bearing is used fully.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of adjustable sliding bearing means, comprise axle sleeve and be arranged on the outer disk of axle sleeve, described axle sleeve is arranged with sliding bearing outward, described sliding bearing comprises at least two bearing splits, described bearing split comprises bearing split ring wall, bearing split ring wall is the cambered surface suitable with the outer side wall radian of axle sleeve by a side of axle sleeve, the common bearing ring body that is set in outside the axle sleeve that forms of the bearing split ring wall of described bearing split, the side that described bearing split ring wall deviates from axle sleeve is provided with bearing (setting) plate, and described bearing (setting) plate adjustable ground is arranged on the disk.

As preferably, described bearing (setting) plate is provided with some adjusting through holes, the side that described bearing (setting) plate deviates from disk is provided with pressing plate, described pressing plate extends through the connecting bolt of regulating through hole and running through disk after being provided with and running through pressing plate, the formation bearing (setting) plate is fixedly connected with disk, and the aperture of described adjusting through hole is greater than the external diameter of described connecting bolt.

After adopting above-mentioned preferred version, when the bearing split of sliding bearing may wear to when to a certain degree needing to regulate, the connecting bolt pine is removed or disassembles, the bearing split is moved bearing split ring wall and the bearing butt that makes the bearing split toward the axle sleeve direction, eliminate the gap between bearing and the axle sleeve, connecting bolt is tightened again, sliding bearing is also surplus to have certain thickness bearing split ring wall fully to be used thereby can make, this regulative mode is simple, and is easy to operate.

As preferably, described axle sleeve is for axially splitting the axle sleeve of splitting of subdivision along axle sleeve, and the described axle sleeve of splitting is arranged with clamping ring outward.After adopting above-mentioned preferred version, adopt above-mentioned preferred version after, can easily the axle sleeve fixed cover be located on the stirring shaft, utilize simultaneously clamping ring to carry out more firmly fixation.

As preferably, described bearing split is preferably 3-8.After adopting above-mentioned preferred version, the quantity of bearing split is preferably above-mentioned quantity, can guarantees that sliding bearing can withstand effect to axle sleeve and stirring shaft from each point of periphery of axle sleeve.

Adjustable sliding bearing means of the present utility model will be that all-in-one-piece sliding bearing changes the sliding bearing that some bearing splits form into originally, these several bearing splits can surround a circle, be equal to a ring body, simultaneously every bearing split all is fixed on the disk, behind sliding bearing abrasion, only need the bearing split is moved toward the axle sleeve center, the gap that wearing and tearing produce is turned down, sliding bearing can normally use again, until the sliding bearing quick-wearing complete till, adopt this structure can take full advantage of sliding bearing, greatly reduce maintenance cost, maintenance time also effectively shortens simultaneously.
