Abstract
The utility model discloses a novel bearing bush. The novel bearing bush comprises a bearing bush body and an oil groove formed in the bearing bush body, wherein the oil groove is formed in the inner side face of the bearing bush body and is of a groove of which an opening is big and a bottom edge is small, two bevel edges of the groove are equal in length, and included angles between the bevel edges and the bottom edge are 100-110 degrees; and the length of the bottom edge of the groove is 0.5-0.8 mm, and the depth of the groove is 0.2-0.5 mm. The shape of the groove is beneficial to the condition that lubricating oil is uniformly conveyed to the surface of a bearing through the oil groove, so that a layer of oil film is formed between the surface of the bearing and a contact face of the bearing bush, and the friction of contact faces of the bearing and the bearing bush is reduced, thus the wear to the bearing bush is reduced, the service life of the bearing bush is prolonged, and meanwhile, the increase of a certain axial force stressed by the bearing bush is facilitated.
Description
Technical field
The utility model relates to a kind of mechanical parts, is a kind of novel bearing shell specifically.
Background technique
Bearing shell is a kind of mechanical parts of widespread usage, present most bearing shell is made by machining, its loaded area is often smaller, the load ratio of bearing is lower, and in use be unfavorable for the formation of the axilemma between bearing and the bearing shell, this just often causes bearing shell easy to wear, and working life is low.
The model utility content
The purpose of this utility model provides a kind of novel bearing shell of using, and its loaded area is big, easily forms oil film during use between bearing and bearing shell, and is not easy to wear, the novel bearing shell of long service life.
For solving the problems of the technologies described above, novel bearing shell of the present utility model comprises bearing shell body and the oil duct that is arranged on the bearing shell body, described oil duct is positioned on the inner side surface of bearing shell body, it is bigger that it is shaped as opening, the groove that the base is less, two hypotenuse equal in length of groove, the angle on hypotenuse and base is 100

0
Bearing shell according to claim 1 is characterized in that: the bottom side length of described groove is 0.5-0.8mm, and the degree of depth of groove is 0.2-0.5mm.
Oil duct is positioned on the inner side surface of bearing shell body, and it is bigger that it is shaped as opening, the groove that the base is less, and two hypotenuse equal in length of groove, the angle on hypotenuse and base is 100
0-110
0This groove shapes is conducive to lubricant oil is transported to bearing equably through groove surface, thereby between the surface of contact of bearing surface and bearing shell, form one deck oil film, reduce the frictional force of the surface of contact of bearing and bearing shell, thereby reduce the wearing and tearing to bearing shell, prolong the working life of bearing shell.
The bottom side length of the groove of bearing shell is 0.5-0.8mm, and the degree of depth of groove is 0.2-0.5mm.Be conducive to increase bearing shell and bear certain axial force.
Description of drawings
Fig. 1 is stereogram of the present utility model.
Embodiment
The utility model is described in further detail to engage accompanying drawing below.By Fig. 1 and Fig. 2 as can be known, bearing shell of the present utility model comprises bearing shell body 1 and the oil duct 2 that is arranged on the bearing shell body, and described oil duct 2 is positioned on the bearing shell inner side surface, it is bigger that it is shaped as opening, the groove that the base is less, two hypotenuse equal in length of groove, the angle on hypotenuse and base is 100
