Abstract
The invention discloses a bearing dustproof structure which comprises bearing outer rings, bearing inner rings and shaft mounting holes in the bearing inner rings, wherein outer roller grooves are formed inside the bearing outer rings; inner roller grooves are formed outside the bearing inner rings; a plurality of rollers are arranged between the outer roller grooves and the inner roller grooves in a rolling mode; male threads are separately arranged on the bearing inner rings at the two sides of each roller; threaded sleeves are mutually engaged with the male threads through female threads; planar dustproof baffle plates are arranged outside the threaded sleeves; avoiding holes which are mutually matched with the shaft mounting holes are formed in the middle of the planar dustproof baffle plates; outer ring-shaped insertion slots are symmetrically formed in the two sides of each bearing outer ring; outer ring-shaped dustproof baffle plates which are separately matched with the outer ring-shaped insertion slots are separately arranged on the planar dustproof baffle plates at the two sides of each bearing outer ring; and inner ring-shaped insertion slots are symmetrically formed in the two sides of each bearing inner ring.
Description
Technical field
The present invention relates to a kind of bearing, more particularly to a kind of bearing dustproof construction.
Background technology
Bearing is a kind of very important parts in contemporary plant equipment.Its major function is support machinery rotation
Body, is used to reduce mechanical load coefficient of friction of the equipment in transmission process.Existing bearing mainly includes：Bearing outer ring, axle
Inner ring and the axle mounting hole being arranged in bearing inner race are held, outer roller groove is provided with the inside of the bearing outer ring, in institute
State and be provided with the outside of bearing inner race interior roller groove, if rolled between the outer roller groove and interior roller groove being provided with
Dry milling.Due to needing to install roller between bearing outer ring and bearing inner race, thus the end face of bearing outer ring and bearing inner race it
Between can there is larger installation gap, in use, some mechanical dust be easy to from install gap enter into outside bearing
Between circle and bearing inner race, aggravate roller and the abrasion between bearing outer ring and bearing inner race, dust-proof effect is poor, then causes axle
Hold service life short, wear rate is high, it is frequent that roller changes number of times.
The content of the invention
The technical problems to be solved by the invention are：A kind of bearing dustproof construction of good dustproof effect is provided.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Bearing dustproof construction, including：Outside bearing
Circle, bearing inner race and the axle mounting hole being arranged in bearing inner race, in the bearing outer ring
Inner side be provided with outer roller groove, interior roller groove is provided with the outside of the bearing inner race, in the outer roller
Rolled between groove and interior roller groove and be provided with some rollers, public affairs are respectively arranged with the bearing inner race of the roller both sides
Screw thread, swivel nut is intermeshed by box thread with male thread, plane dust-proof guard is provided with the outside of the swivel nut, described
The avoidance hole cooperated with axle mounting hole is provided with the middle part of plane dust-proof guard, is symmetrically set in the both sides of the bearing outer ring
Outer annular slot is equipped with, is respectively arranged with the plane dust-proof guard of the bearing outer ring both sides and outer annular slot phase interworking
The outer annular dust-proof guard for closing, is symmetrically arranged with annular slot, in the bearing inner race two in the both sides of the bearing inner race
The annular dust-proof guard cooperated with annular slot is respectively arranged with the plane dust-proof guard of side.
It is an advantage of the invention that：Above-mentioned bearing dustproof construction, by plane dust-proof guard and inside-and-outside ring dust-proof guard energy
Enough effectively prevent in the installation gap that mechanical dust is entered between bearing outer ring and bearing inner race end face, reduce roller and bearing
Additional wear between outer ring and bearing inner race, good dustproof effect, rollers wear rate is low, bearing long service life.

Specific embodiment
Particular content of the invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, bearing dustproof construction, including：Bearing outer ring 1, bearing inner race 2 and it is arranged in bearing inner race 2
Axle mounting hole 3, outer roller groove 4 is provided with the inner side of the bearing outer ring 1, is provided with the outside of the bearing inner race 2
Interior roller groove 5, rolls between the outer roller groove 4 and interior roller groove 5 and is provided with some rollers 6, in the roller 6
Male thread 7 is respectively arranged with the bearing inner race 2 of both sides, swivel nut 8 is intermeshed by box thread 9 with male thread 7, in the spiral shell
The outside of set 8 is provided with plane dust-proof guard 10, is provided with the middle part of the plane dust-proof guard 10 mutual with axle mounting hole 3
The avoidance hole 11 of cooperation, outer annular slot 12 is symmetrically arranged with the both sides of the bearing outer ring 1, in 1 liang of the bearing outer ring
The outer annular dust-proof guard 13 cooperated with outer annular slot 12 is respectively arranged with the plane dust-proof guard 10 of side, described
The both sides of bearing inner race 2 are symmetrically arranged with annular slot 14, divide on the plane dust-proof guard 10 of the both sides of the bearing inner race 2
The annular dust-proof guard 15 cooperated with annular slot 14 is not provided with.
Above-mentioned bearing dustproof construction, mechanical powder can be effectively prevented by plane dust-proof guard and inside-and-outside ring dust-proof guard
In the installation gap that dirt is entered between bearing outer ring and bearing inner race end face, reduce roller and bearing outer ring and bearing inner race it
Between additional wear, good dustproof effect, rollers wear rate is low, bearing long service life.
