Description
Technical field
The utility model relates to a kind of sealed type tapered roller bearing, belongs to mechanical field.
Background technique
Tapered roller bearing is widely used in the industries such as automobile, milling train, mine, metallurgy, plastics machinery, this class bearing is divided into the different structural types such as single-row, biserial and four-row tapered roller bearing by the columns of filled roller, and single-row tapered roller bearing can bear radial load and single direction axial load.The ability that single-row tapered roller bearing bears axial load depends on wrapping angle, i.e. outer ring raceway angle, and angle is larger, and axial load ability is also larger.What in tapered roller bearing, consumption was maximum is single-row tapered roller bearing.
Tapered roller bearing comprises conical inner ring and outer ring raceway, and tapered roller is arranged between the two.The projection line of all conical surfaces is all met in the same point of bearing axis.This design makes tapered roller bearing be particularly suitable for bearing compound (radially with axially) load.The axial load ability major part of bearing is determined by wrapping angle α; α angle is larger, and axial load ability is just higher.
At present, the design of single-row tapered roller bearing is open architecture, without any sealing configuration or dustproof construction, open type design bearing, because of its function that does not possess any the isolation external world with bearing working district, causes bearing working life and running accuracy to be subject to the impact of operating mode larger.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, good sealed type tapered roller bearing of sealability.
The technological scheme that realizes the utility model object is:
A kind of sealed type tapered roller bearing, comprise bearing outer ring, bearing inner race, rolling element, retainer and seal ring, between described bearing inner race and outer ring, form an annular space, in this annular space, be provided with tapered raceway, rolling element is arranged in tapered raceway by retainer; Described seal ring comprises skeleton and the O-ring seal being fastened on skeleton outer surface, and O-ring seal one end is arranged on the exterior edge face of bearing inner race by skeleton, the exterior edge face interference fit of the other end and bearing outer ring.
As preferably, the cross section of above-mentioned skeleton is L shaped, and the internal surface of two right angle sides is separately fixed on the exterior edge face and external diameter of bearing inner race, and wherein, skeleton internal diameter and bearing inner race are interference fit.
The lip of the O-ring seal one end on above-mentioned seal ring and the exterior edge face interference fit of bearing inner race, the exterior edge face interference fit of the lip of the other end and bearing outer ring, isolates bearing working district and the external world completely.
Described bearing outer ring, bearing inner race, rolling element all adopt GCr15 steel to make, and the skeleton on retainer and seal ring adopts No. 10 steel plates to make, and O-ring seal adopts nitrile butadiene rubber to make.
The utlity model has positive effect: sealed type tapered roller bearing described in the utility model, directly on the exterior edge face of bearing inner race and outer ring, seal ring is set, simple in structure, effectively solve the problem that bearing working district is isolated from the outside, there is oil-leakage-prevention, dust reduction capability, improved the applying working condition of bearing, promoted working life and the precision of bearing, and practicability is good, cost is low.
Brief description of the drawings
For content of the present utility model is more likely to be clearly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
