Abstract
The utility model relates to an improved generation cover that expands, the internal surface of preventing wearing and tearing, for realizing above-mentioned purpose, the utility model provides a following technical scheme: the utility model provides an improved generation cover that expands, includes endotheca, overcoat and bolt, characterized by: the jacket is provided with a cavity, the cavity is provided with an inner surface, and an oil supply structure is axially arranged on the inner surface.
Description
Technical Field
The utility model relates to an expand set technical field, concretely relates to improved generation cover that expands.
Background
Expansion sleeve (also known asExpansion coupling sleeveKey-free bearing, etc.) is a keyless connection device, and its principle and application are that under the action of high-strength tension bolt, a great holding force is produced between inner ring and shaft and between outer ring and wheel hub so as to implement keyless connection of machine member and shaft. When bearing load, the combined pressure of the expansion sleeve and the machine member and the shaft and the accompanying friction force are used to transmit torque and axial force or the composite load of the torque and the axial force.
The expansion sleeve has long service life, and when the expansion sleeve is overloaded, the expansion sleeve loses the linking effect, so that the equipment can be protected from being damaged. However, when the expansion sleeve is in use, after the expansion sleeve is in contact with the inner opening shaping grinding tool for a long time, the inner surface of the expansion sleeve is easy to wear, so that the inner opening shaping grinding tool is easy to damage, and the service lives of the inner opening shaping grinding tool and the expansion sleeve are shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide an improved generation cover that expands, the internal surface of preventing wearing and tearing.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an improved generation cover that expands, includes endotheca, overcoat and bolt, characterized by: the jacket is provided with a cavity, the cavity is provided with an inner surface, and an oil supply structure is axially arranged on the inner surface.
The utility model discloses further setting is: the oil supply structure comprises an oil storage tank, the oil storage tank is axially arranged along the inner surface, and an oil storage piece is arranged in the oil storage tank.
The utility model discloses further setting is: the oil storage piece is a sponge plate, and lubricating oil is soaked in the sponge plate.
The utility model has the characteristics as above: the lubricating structure lubricates the inner surface, reduces friction and prevents abrasion.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
