Description
Technical field
The utility model relates to the device technique field for the protection of rotating shaft, particularly relates to a kind of axle sleeve.
Background technique
As everyone knows, axle sleeve is a kind of device for the protection of rotating shaft, is widely used in industrial field; Existing axle sleeve comprises tubular body, in use, axle sleeve is sleeved on the rotating shaft outside, and rotating shaft often contacts with axle sleeve in rotation process, thereby need to take in lubricant oil and reduce the damage that axle sleeve and rotating shaft contact friction cause, and when taking in lubricant oil between existing axle sleeve and the rotating shaft, usually axle sleeve is taken off, after be loaded on after taking in lubricant oil to the sleeve lining, bother very much, and take off frequently the reduction in working life that axle sleeve can cause axle sleeve.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of and conveniently takes in lubricant oil, thus easy to use and effective guarantee the axle sleeve in working life.
Axle sleeve of the present utility model, comprise tubular body, be provided with the first groove, the second groove and the 3rd groove on the described main body inner wall, described the second groove is between described the first groove and the 3rd groove, be provided with the first through hole, the second through hole and third through-hole on the described main wall, and be provided with the first capping in described the first through hole; Described the second through hole is provided with the second capping; Described third through-hole place is provided with the 3rd capping, and described the first through hole is communicated with the first groove; Described the second through hole is communicated with the second groove; Described third through-hole is communicated with the 3rd groove.
Axle sleeve of the present utility model also comprises the 4th groove, and described the 4th groove is positioned on the described main body inner wall, and described the 4th groove all is communicated with the first groove, the second groove and the 3rd groove.
Axle sleeve of the present utility model, described the first groove, the second groove and the 3rd groove are set in parallel on the described main body inner wall.
Compared with prior art the beneficial effects of the utility model are: be provided with the first groove, the second groove and the 3rd groove in main body inner wall, the second groove is between the first groove and the 3rd groove, be provided with the first through hole, the second through hole and third through-hole on the main wall, and be provided with the first capping in the first through hole; The second through hole is provided with the second capping; The third through-hole place is provided with the 3rd capping, and the first through hole is communicated with the first groove; The second through hole is communicated with the second groove; Third through-hole is communicated with the 3rd groove; Like this, can be by in the first through hole, the second through hole and third through-hole, taking in lubricant oil, lubricant oil enters respectively the first groove, the second groove and the 3rd groove from the first through hole, the second through hole and third through-hole, thereby play lubrication between whole countershaft and the axle sleeve, and need not pull down and get final product, easy to use and effective guarantee working life.
Description of drawings
Fig. 1 is vertical sectional structure schematic representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, axle sleeve of the present utility model, comprise tubular body 1, be provided with the first groove 2, the second groove 3 and the 3rd groove 4 on the main body inner wall, the second groove is between the first groove and the 3rd groove, be provided with the first through hole, the second through hole and third through-hole on the main wall, and be provided with the first capping 5 in the first through hole; The second through hole is provided with the second capping 6; The third through-hole place is provided with the 3rd capping 7, the first through holes and is communicated with the first groove; The second through hole is communicated with the second groove; Third through-hole is communicated with the 3rd groove; Like this, can be by in the first through hole, the second through hole and third through-hole, taking in lubricant oil, lubricant oil enters respectively the first groove, the second groove and the 3rd groove from the first through hole, the second through hole and third through-hole, thereby play lubrication between whole countershaft and the axle sleeve, and need not pull down and get final product, easy to use and effective guarantee working life.
Axle sleeve of the present utility model comprises that also the 4th groove 8, the four grooves are positioned on the main body inner wall, and the 4th groove all is communicated with the first groove, the second groove and the 3rd groove, like this, and can be so that lubricant oil distributes more even.
Axle sleeve of the present utility model, the first groove, the second groove and the 3rd groove are set in parallel on the main body inner wall.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
