The eccentric balance sleeve is a part inside the eccentric bearing, and the eccentric bearing is a very common bearing and mainly consists of an eccentric sleeve, and the two bearings are combined together to form a new bearing. The eccentric balanced sleeve is mainly composed of an eccentric sleeve, an outer ring, an inner ring, rolling bodies, a bearing A and a bearing B, and is mainly driven by a common three-phase asynchronous motor during operation, then an input shaft of a speed reducer is driven to rotate, the eccentric balanced sleeve is generally formed by integrally processing, the eccentric balanced sleeve can be burnt in the use process, abrasion is large, the eccentric balanced sleeve needs to be detached and replaced after the eccentric balanced sleeve is worn to a certain degree, the balanced sleeve is in interference connection with a shaft rod through a flat key, the replacement process is relatively troublesome, and meanwhile the whole replacement results in serious material waste.

Disclosure of Invention

According to the technical problem, the novel eccentric balance sleeve provided by the utility model adopts a split design, so that one side with serious abrasion can be independently replaced, meanwhile, the flat key connection is replaced to be more flexible sliding key connection, and the quick disassembly is realized by matching with the positioning bolt.

The technical scheme is as follows: the utility model provides a novel eccentric balance cover, includes eccentric cover piece, the upper portion right side of eccentric cover piece be provided with balance sleeve pipe, its characterized in that, eccentric cover piece and balance sleeve pipe's junction be provided with sliding connector assembly to shaft end fixer subassembly is installed respectively on balance sleeve pipe's upper portion left side and eccentric cover piece's lower part right side.

Preferably, the sliding connector assembly comprises an outer limit ring, an inner fixed clamping block is welded on the inner side of the outer limit ring, and a movable limit clamping block is arranged on the upper portion of the outer limit ring.

Preferably, the shaft end fixer assembly comprises an outer shaft sleeve, a connecting key groove is formed in the inner side of the outer shaft sleeve, and limit bolts are respectively connected with the front end and the rear end of the outer shaft sleeve in a threaded mode.

Preferably, the inner fixed clamping blocks and the movable limiting clamping blocks are respectively provided with four, and are arranged at intervals.

Preferably, the outer limit ring and the inner fixed clamping block are respectively integrally arranged on the right side of the upper part of the eccentric sleeve block.

Preferably, the movable limiting clamping block is integrally arranged on the left side of the lower portion of the balance sleeve, and is inserted into the inner side of the outer limiting ring.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the utility model, the arrangement of the outer limit ring, the inner fixed clamping block and the movable limit clamping block is beneficial to fixing the relative positions of the eccentric sleeve block and the balance sleeve, and the split design is convenient to detach and replace.

2. According to the utility model, the arrangement of the outer shaft sleeve, the connecting key groove and the limiting bolt is beneficial to replacing the original flat key interference connection mode with sliding key gap connection, and normal use after connection is ensured by matching with the limiting bolt.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

examples:

as shown in fig. 1, a novel eccentric balance sleeve comprises an eccentric sleeve block 1, wherein a balance sleeve 2 is arranged on the right side of the upper part of the eccentric sleeve block 1, and the novel eccentric balance sleeve is characterized in that a sliding connector assembly 3 is arranged at the joint of the eccentric sleeve block 1 and the balance sleeve 2, and shaft end fixing assemblies 4 are respectively arranged on the left side of the upper part of the balance sleeve 2 and the right side of the lower part of the eccentric sleeve block 1.

In the above embodiment, specifically, the outer sleeve 41 is integrally provided on the lower right side of the eccentric sleeve block 1 and the upper left side of the balance sleeve 2, respectively.

In the above embodiment, specifically, the right side of the inside of the eccentric sleeve block 1 and the left side of the inside of the balance sleeve 2 are provided with shaft holes, and the shaft holes of the inside of the balance sleeve 2 of the shaft hole of the inside of the eccentric sleeve block 1 are vertically aligned.

In the above embodiment, specifically, the inner fixed clamping block 32 and the moving limiting clamping block 33 are respectively located at the peripheral positions of the shaft hole.

Principle of operation

The working principle of the utility model is as follows: the staff installs eccentric sleeve piece 1 or balance sleeve 2 on the axostylus axostyle earlier to the inboard that the axostylus axostyle runs through outside axle sleeve 41 is located the inboard in shaft hole, and catch up with the inboard that fixed feather key is located connecting keyway 42, then the staff screws up stop bolt 43, make stop bolt 43 jack-up in the position of axostylus axostyle, fix the axial position of junction, overlap remaining eccentric sleeve piece 1 and balance sleeve 2 on the axostylus axostyle again, and the installation opposite direction of eccentric sleeve piece 1 and balance sleeve 2, guarantee simultaneously to remove the inboard of inserting outside spacing collar 31 after spacing fixture block 33 and inboard fixed fixture block 32 are crisscross, finally screw up stop bolt 43 again, accomplish the installation.

By using the technical scheme of the utility model or under the inspired by the technical scheme of the utility model, a similar technical scheme is designed by a person skilled in the art, so that the technical effects are achieved, and the technical effects fall into the protection scope of the utility model.
