The utility model solves the defects of poor lubrication and rapid part abrasion caused by no design of a lubricating oil way or a lubricating channel of the existing spiral limited slip differential, and ensures that the product has the advantages of excellent lubricating effect and reduced part abrasion.
Description
Technical Field
The utility model relates to the technical field of automobile transmission part assemblies, in particular to a gasket with an oil groove, which is applied to a helical gear limited slip differential.
Background
When the helical tooth limited slip differential operates, enough lubricating oil is required to flow into the parts of the differential due to continuous friction of the parts, so that the surfaces of the parts are provided with complete oil films, and the friction surfaces are ensured to be well lubricated. However, when the assembly runs at a low speed, the lubricating oil flows slowly, and no special lubricating oil way or channel is designed, so that the parts are easily worn quickly. Particularly, when the assembly is just started, because the oil temperature is low and the oil cannot splash for lubrication, a complete oil film cannot be formed on the contact surface of parts, so that dry friction among the parts is caused, and the abrasion of the parts is aggravated. In winter in the north, the phenomenon of aggravation of abrasion is more prominent, and the assembly is easy to lose efficacy.
Chinese patent "an anti-wear parallel shaft type limited slip differential", publication No. CN203641435U, granted publication No. 2014.06.11, describes in its disclosure a gasket, whose two working planes are not designed with lubrication oil passages and channels, and have lubrication defects.
The gasket of the existing spiral tooth limited slip differential is a common gasket or a wear-resistant gasket, and a lubricating oil way and a lubricating oil channel are not designed, so that the defect of quick abrasion of assembly parts is caused.
SUMMERY OF THE UTILITY MODEL
In view of the problems of the prior art, an object of the present invention is to provide a gasket with an oil groove having a lubricating effect and an excellent lubricating effect.
In order to achieve the purpose, the gasket with the oil groove comprises a body and is characterized in that: the body is provided with coaxial through holes; a plurality of oil grooves are uniformly distributed on two end faces of the body at intervals, and each oil groove is used for communicating the outer periphery and the inner periphery of the body; the oil groove is semicircular.
Preferably, both ends of the semicircular ring are communicated with the periphery of the body, and the top of the semicircular ring is communicated with the inner periphery of the body.
Preferably, the projections of all the oil grooves have no intersection point on the projection of the body axis.
Further preferably, on the projection of the body axis, central angles between the oil groove on the same surface and two oil grooves on the other surface adjacent to the oil groove on the same surface are respectively alpha and beta, and alpha is larger than beta.
The utility model has the beneficial effects that: compared with the prior art, the structure has the advantages that the differential mechanism is well lubricated, convenient to maintain and lower in cost; lubricating oil can flow through from the oil groove, has improved lubricated efficiency and radiating efficiency.
The utility model can improve the lubricating effect of the product and reduce the abrasion of parts.
The utility model solves the defects of poor lubrication and rapid part abrasion caused by no design of a lubricating oil way or a lubricating channel of the existing spiral limited slip differential, and ensures that the product has the advantages of excellent lubricating effect and reduced part abrasion.

Detailed Description
The technical solutions of the present invention (including the preferred ones) are further described in detail by way of fig. 1 to 2 and enumerating some alternative embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
As shown in fig. 1 and 2, the gasket with the oil groove designed by the utility model comprises a body 1, wherein the body 1 is provided with a coaxial through hole 2; a plurality of oil grooves 3 are uniformly distributed on two end faces of the body 1 at intervals, and each oil groove 3 communicates the outer periphery and the inner periphery of the body 1; the oil groove 3 is semicircular.
The both ends of semicircle annular all communicate with the periphery of body 1, semicircle annular top and the interior circumference intercommunication of body 2. Thus, an oil passage is formed.
On the projection of body axis, the projection of all oil grooves 3 does not have the intersect, that is to say, six oil grooves in this embodiment are crisscross setting each other, and the oil groove of body 1 tow sides all is the equipartition, all is equipped with the oil groove of three equipartition at each working face of body 1, adjacent 120 between them. And central angles between the oil groove on the same surface and the two oil grooves on the other surface adjacent to the oil groove on the same surface are respectively alpha and beta, and alpha is larger than beta.
When the helical gear limited slip differential performs a differential function, the side gear rotates, and the side gear generates oil pumping capacity. Lubricating oil can flow through the oil groove in the gasket, and can play the roles of lubricating, radiating and flushing. When the helical gear limited slip differential does not perform a differential function, the side gear does not rotate. Because the whole differential mechanism rotates, lubricating oil can also flow through the gasket oil groove, and therefore the effects of lubrication, heat dissipation and flushing can also be achieved. When the vehicle is not started, lubricating oil can be stored in the oil groove due to the existence of the gasket oil groove, and when the vehicle is started, the lubricating oil stored in the gasket oil groove can be quickly distributed on the surface of a part, so that the abrasion of the part is reduced.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the utility model, and any modification, combination, replacement, or improvement made within the spirit and principle of the present invention is included in the scope of the present invention.
