Abstract
The utility model discloses a gear with a gear end face provided with a back pressure oil ring groove . The gear with the gear end face provided with the back pressure oil ring groove comprises a gear and is characterized in that three to five grooves with the same size are formed in the end face encircling the gear, each tooth top on the gear is respectively provided with a straight groove with the same size, the straight grooves on tooth tops are communicated with a first groove which is adjacent to the gear end face, the width of each groove is from 0.5 millimeter to 0.8 millimeter, the depth of each groove is 0.5 millimeter, and the depth of each groove is the same with the depth of each straight groove. The gear with the gear end face provided with the back pressure oil ring groovehas the advantages of being simple in structure, long in service life, and capable of reducing friction, improving lubrication performance of the gear and meanwhile reducing maintenance cost.
Description
Technical field
The utility model relates to a kind of gear, is specifically related to the gear that a kind of increment is worn the back pressure oil ring groove.
Background technique
Gear mainly is for power transmission, and the end face of gear is usually and axle sleeve uses that combine, and present gear is combining with axle sleeve, because long the friction causes the wearing and tearing of gear face and end face of shaft bush, and usually more gear changing and axle sleeve.Also some producer produces gear with some high-abrasive materials, but when long-term work, the increment face produces a large amount of heat because of the lubricated gear that causes that does not have olein, and the while is the damage gear of indirect also.
The model utility content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and long service life can reduce friction, improves the greasy property of gear, and a kind of increment that has reduced simultaneously maintenance cost is worn the gear of back pressure oil ring groove.
A kind of increment is worn the gear of back pressure oil ring groove, comprises gear, it is characterized in that: have the groove of the equal size in 3 ~ 5 roads round the end face of gear, each crown on the gear respectively has the straight trough of equal size.
The first groove that straight trough on the described crown is adjacent with gear face communicates.
The width of described groove is between 0.5mm ~ 0.8mm, and the degree of depth is 0.5mm.
The degree of depth of described groove is deeply identical with straight trough.
The beneficial effects of the utility model are: simple in structure, long service life can reduce friction, improves the greasy property of gear, has reduced simultaneously maintenance cost.
Description of drawings
Fig. 1 is the utility model gear face structural representation;
Fig. 2 is the utility model gear and axle sleeve position relationship structural representation.
Among the figure: the 1-gear; The 2-groove; The 3-straight trough; The 11-crown; The 4-axle sleeve.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-2, a kind of increment is worn the gear of back pressure oil ring groove, comprises gear 1, has the groove 2 of the equal size in 3 ~ 5 roads round the end face of gear 1, and each crown 11 on the gear 1 respectively has the straight trough 3 of equal size.
The first groove 2 that straight trough 3 on the crown 11 is adjacent with gear 1 end face communicates.
The width of groove 2 is between 0.5mm ~ 0.8mm, and the degree of depth is 0.5mm.
The degree of depth of groove 2 is deeply identical with straight trough 3.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (4)
