Technical Field
The utility model relates to a machine-building, chemical production field equipment especially relate to a skeleton axle sleeve for oil blanket of convenient dismouting.
Background
The framework oil seal can cause abrasion to a shaft in a long-term use process, so that sealing failure is caused. If the worn shaft is replaced or repaired, the equipment is stopped for a long time, and the production is influenced; but also generates corresponding cost, and increases the production cost of enterprises.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a skeleton is axle sleeve for oil blanket of convenient dismouting is provided, has overcome prior art's above-mentioned shortcoming, has and can avoid the skeleton oil blanket to produce wearing and tearing at the counter shaft in long-term running in-process, does not increase enterprise's manual work and manufacturing cost's characteristics moreover.
The utility model discloses the technical problem that solve is realized through following technical scheme:
a shaft sleeve for installing a framework oil seal, which is convenient to disassemble and assemble, comprises a shaft and a framework oil seal arranged on an equipment shell; a shaft sleeve is arranged between the outer diameter of the shaft and the inner diameter of the lip opening of the framework oil seal in a matching manner;
a fastening ring is arranged at the end part of the shaft sleeve, and a through hole is formed in the fastening ring in the axial direction; the shaft sleeve is provided with a threaded hole; the shaft sleeve and the fastening ring are screwed into a threaded hole through a hexagonal head bolt penetrating through the through hole and then fixedly connected into a whole;
the fastening ring is also provided with a thread through hole in the radial direction, and a screw screwed in through the thread through hole penetrates through the fastening ring and then abuts against the shaft, so that the fastening ring is fixedly connected to the shaft.
Preferably, a groove is formed in the inner hole side of the shaft sleeve, and an O-shaped sealing ring is arranged in the groove; and the clearance between the shaft and the inner hole of the shaft sleeve is matched with the sealing size of the O-shaped ring.
Preferably, the clamping ring is provided with two through holes in the axial direction.
Preferably, the fastening ring is provided with two threaded through holes in the radial direction.
The utility model discloses following beneficial effect has:
because relative rotation exists between the framework oil seal and the shaft, the framework oil seal generates abrasion to the shaft after running for a certain time, and sealing failure is caused. When the shaft becomes worn, the shaft must be repaired or replaced to ensure sealing, which is time consuming and results in relatively high repair costs. Through the utility model provides a structural design can solve this problem well. Not only reduces the workload of maintenance personnel, but also reduces the production and operation cost of enterprises to a certain extent.

Detailed Description
As shown in fig. 1, 2 and 3, the shaft sleeve for the framework oil seal, which is convenient to disassemble and assemble, comprises a shaft 10 arranged on an equipment shell 9 and the framework oil seal 3; a shaft sleeve 4 is arranged between the outer diameter of the shaft 10 and the inner diameter of the lip opening of the framework oil seal 3 in a matching way; the outer diameter of the shaft sleeve 4 is matched with the inner diameter of the lip opening of the framework oil seal 3, and the interference magnitude between the outer diameter of the shaft sleeve and the lip opening of the framework oil seal meets the installation and use standards of the framework oil seal;
a groove is formed in the inner hole of the shaft sleeve 4, an O-shaped sealing ring 8 is arranged in the groove, and a sealing effect is achieved between the shaft 10 and the inner hole of the shaft sleeve 4;
and the clearance between the shaft 10 and the inner hole of the shaft sleeve 4 is matched with the sealing size of an O-shaped ring.
In order to fix the shaft sleeve 4 on the shaft 10 and facilitate disassembly and assembly, two threaded holes are formed in the shaft sleeve 4 in the axial direction; a fastening ring 5 is arranged at the end part of the shaft sleeve 4; two through holes are arranged on the fastening ring 5 in the axial direction at the positions corresponding to the two threaded holes on the shaft sleeve 4; the hexagon head bolt 6 penetrates through the fastening ring 5 and then is screwed into the shaft sleeve 4, and after the hexagon head bolt 6 is fastened, the shaft sleeve 4 and the fastening ring 5 are fixed into a whole.
Two threaded through holes are further formed in the radial direction of the fastening ring 5, and a screw 7 passing through the threaded through hole is screwed into the fastening ring 5 and then abuts against the shaft 10, so that the fastening ring 5 can be fixed on the shaft 10.
When the shaft sleeve 4 is worn and needs to be replaced, the two screws 7 are screwed out for a certain length. And the hexagon head bolt 6 is screwed out from the axle sleeve screw hole. The tightening ring 5 is pulled out to the atmosphere side for a certain distance, then the screw 7 is fastened on the shaft 10, the hexagon head bolt 6 is screwed in again, at the moment, along with the rotation of the hexagon head bolt 6, the shaft sleeve 4 slowly moves on the shaft 10 and is pulled out to the atmosphere side, and the state is shown in figure 3.
During the design of the shaft sleeve 4 and the fastening ring 5, the size and the material of related components can be further designed and adjusted by combining with the actual use working conditions.
The utility model discloses a design of axle sleeve is used, can avoid the skeleton oil blanket to produce wearing and tearing at the counter shaft in long-term use. After the shaft sleeve is worn, the shaft sleeve can be directly replaced or repaired without replacing or repairing the shaft. In addition, when the framework oil seal is replaced, only part of the equipment is required to be detached. Therefore, in order to facilitate the disassembly and assembly of the shaft sleeve, the utility model discloses the shaft sleeve is designed into the structural style of the disassembly and assembly of being convenient for.
