Abstract

The utility model gives a kind of high temperature rolling bearing, comprises outer ring, inner ring and rolling element, has the rolling groove placing rolling element, be provided with cooling water channel in outer ring between outer ring and inner ring, and outer ring also has and is communicated with cooling water channel and outside water inlet and osculum.Water inlet to outer ring passes into cooling water, and cooling water flows out from osculum through cooling water channel, and in this process, cooling water reduces the temperature of outer ring and Ben Gaowen rolling bearing, extends the working life of Ben Gaowen rolling bearing.

Description

High temperature rolling bearing
Technical field
The utility model relates to a kind of rolling bearing, the rolling bearing particularly worked under a kind of high temperature, vacuum environment.
Background technique
Rolling bearing is widely used in common mechanical structure, but common bearing is difficult to normally work under the environment of high temperature, ultravacuum.
Model utility content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the high temperature rolling bearing of long service life.
For solving the problems of the technologies described above, the utility model provides a kind of high temperature rolling bearing, comprises outer ring, inner ring and rolling element, has the rolling groove placing rolling element between outer ring and inner ring, be provided with cooling water channel in outer ring, outer ring also has and is communicated with cooling water channel and outside water inlet and osculum.
After adopting such structure, the water inlet to outer ring passes into cooling water, and cooling water flows out from osculum through cooling water channel, and in this process, cooling water reduces the temperature of outer ring and Ben Gaowen rolling bearing, extends the working life of Ben Gaowen rolling bearing.
The cycle surface of this high temperature rolling bearing has cooling water groove, the opening that cooling water groove is in cycle surface is sealed by welded closure plate, form cooling water channel between cooling water groove and shut, outer ring outer side wall also has the water inlet communicated with cooling water channel and osculum.
After adopting such structure, cold anhydrating is made up of cooling water groove and shut, reduces the difficulty of processing, is convenient to industrial production.
The outer ring of this high temperature rolling bearing also has the mounting hole communicated with rolling groove; After adopting such structure, the convenient process using can change inner rolling element by mounting hole as required.
Accompanying drawing explanation
Fig. 1 is the plan view of Ben Gaowen rolling bearing embodiment.
Fig. 2 is the plan view of Ben Gaowen rolling bearing embodiment.
Fig. 3 is the A-A sectional view of Fig. 1.
Fig. 4 is the B-B sectional view of Fig. 2.
Embodiment
(understand technology contents of the present utility model to remove, a rolling element is only shown in Fig. 3) as shown in Figures 1 to 4.
This high temperature rolling bearing comprises outer ring 1, inner ring 2 and rolling element 3, and inner ring 2 is sleeved on inside outer ring 1, has the rolling groove 4 placing rolling element 3 between outer ring 1 and inner ring 2, and rolling element 3 is rolling steel ball.
Outer ring 1 front-end face has cooling water groove 1a, cooling water groove 1a walks around the surface, outer ring 1 of the overwhelming majority, the opening that cooling water groove 1a is in outer ring 1 front-end face is sealed by welded closure plate 1b, forms cooling water channel 1c between cooling water groove 1a and shut 1b;
Outer ring 1 outer side wall has mounting hole 1d, water inlet 1e and osculum 1f, water inlet 1e and osculum 1f extends in cooling water channel 1c, and mounting hole 1d extends in rolling groove 4.
The inner ring 2 of this high temperature rolling bearing is sleeved in rotating shaft, outer ring 1 and external equipment are fixed, during use, water inlet 1e to outer ring 1 passes into cooling water, reduce the temperature of outer ring 1 and Ben Gaowen rolling bearing, extend the working life of Ben Gaowen rolling bearing, cooling water flows out from osculum 1f through cooling water channel 1c.
This high temperature rolling bearing can change inner rolling element 3 by mounting hole 1d as required in the process used.
This high temperature rolling bearing can under ultrahigh vacuum and the ambient stable work of temperature more than 400 degrees Celsius.
Above-described is only a kind of mode of execution of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
