Abstract

An elastic spacer bush of a transmission shaft of an automobile axle speed reducer consists of three sections including a big-end section, a taper section and a small-end section integrally, wherein the big-end section transits to the small-end section by the aid of the taper section. A plurality of lubricating holes are arranged on the elastic spacer bush, and the lubricating holes are communicated with an axle hole of the elastic spacer bush. By the aid of the lubricating holes arranged on the elastic spacer bush, a gear lubricating oil passage is formed between two tapered roller bearings, and accordingly cooling effect of gear lubricating oil is guaranteed, and noise of the tapered roller bearings during rotation is reduced.

Description

A kind of automotive axle retarder transmission shaft collapsible dist collar
Technical field
The utility model relates to a kind of auto-parts, particularly a kind of collapsible dist collar that is installed on the automotive axle retarder intermediate solid drive shaft.
Background technique
Between two tapered roller bearings before and after the collapsible dist collar of automotive axle retarder is installed on the reducer shell intermediate solid drive shaft, when the roller of tapered roller bearing or Internal and external cycle wearing and tearing, rely on the flexible of collapsible dist collar decrement, guarantee that two tapered roller bearings can turn round under normal load the redeeming of tapered roller bearing wear extent.Existing collapsible dist collar as shown in Figure 3, whole collapsible dist collar is formed by three sections, one section is that big end section be that 2, one sections of tapered sections be small end section 3 for 1, one section, passes through tapered section 2 transition between big end section 1 and the small end section 3.
There are the following problems in the course of the work for existing collapsible dist collar: because collapsible dist collar seals the inner chamber between two tapered roller bearings on the reducer shell intermediate solid drive shaft, be unfavorable for gear lubricant heat radiation between two tapered roller bearings, increased the noise when tapered roller bearing rotates.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of collapsible dist collar that has lubrication hole is provided.
The technical solution of the utility model is: a kind of automotive axle retarder transmission shaft collapsible dist collar, and whole collapsible dist collar is formed by three sections, and one section is big end section, and one section is tapered section, and one section is the small end section, the big end between section and the small end section by the tapered section transition.Be provided with a plurality of lubrication holes at collapsible dist collar, lubrication hole communicates with the axis hole of collapsible dist collar.
The utility model compared with prior art has following characteristics:
The collapsible dist collar that the utility model provides is provided with lubrication hole, has formed the passage of gear lubricant between two tapered roller bearings, has guaranteed the radiating effect of gear lubricant, has reduced the noise that tapered roller bearing produces when rotating.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the left view in the accompanying drawing 1;
Accompanying drawing 3 is existing collapsible dist collar structural representation.
Embodiment
Shown in accompanying drawing 1,2: a kind of automotive axle retarder transmission shaft collapsible dist collar, whole collapsible dist collar is formed by three sections, and one section is that big end section is that 2, one sections of tapered sections are small end section 3 for 1, one section, the big end between section 1 and the small end section 3 by tapered section 2 transition.Be provided with four row's lubrication holes 4, four row lubrication holes 4 at collapsible dist collar and be evenly distributed on the collapsible dist collar along the axis of collapsible dist collar, four of every rows, lubrication hole 4 communicates with the axis hole 5 of collapsible dist collar.

Claims (1)
