Description
Technical field
The utility model relates to field of bearings, particularly relates to a kind of bearing unit.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.By the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two class.
Bearing is generally used for connection fixing base and axle, to reduce the frictional force between axle and fixed base.Under prior art condition, being provided with the chamber for injecting lubricant oil in axle and fixed base, to reduce the frictional force of bearing further, reaching the object of heat radiation simultaneously.But common bearing unit only has a pouring orifice, and pouring orifice is in the side of bearing, the lubricant oil convection current of bearing both sides is less, regional area heat is concentrated.
Model utility content
The utility model is in order to overcome deficiency of the prior art, provide a kind of bearing unit, this bearing unit can inject lubricant oil from the both sides of bearing, promote the flowing of lubricant oil, accelerate the transmission of heat, thus being conducive to cooling, the good sealing effect simultaneously between this bearing unit and axle, avoids the leakage of lubricant oil.
The utility model is achieved through the following technical solutions:
A kind of bearing unit, comprise upper end cap, fixed base, lower end cap, bearing, described upper end cap, fixed base, be fixedly connected with between lower end cap, described bearing and axle interference fit, described axle is provided with jump ring, described upper end cap is provided with pouring orifice, described pouring orifice is provided with plug cock A, described axle is through lower end cap, two annular grooves are provided with inside the hole that described lower end cap coordinates with axle, gasket ring is provided with in described annular groove, described lower end cap is provided with runner, flow passage entry is provided with plug cock B, described runner passes into the cavity between lower end cap and bearing.
As optimal technical scheme of the present utility model, be bolted to connection between described upper end cap, fixed base, lower end cap, bolt is through in the bolt hole be screwed into after upper end cap, fixed base on lower end cap.
As optimal technical scheme of the present utility model, described lower end cap is provided with projection, described projection withstands the side of the outer ring of bearing.
As optimal technical scheme of the present utility model, between described upper end cap and fixed base, be provided with pad.
Compared with prior art, the beneficial effects of the utility model are: upper end cap of the present utility model and lower end cap are provided with pouring orifice, lubricant oil can be injected from the both sides of bearing, promote the flowing of lubricant oil, the fitting surface of simultaneously lower end cap and axle is provided with two annular grooves, the gasket ring arranged in annular groove, can play the effect of double seal, reduces and leaks.
