Abstract
The utility model discloses a kind of motor of dust collector bearing with dustproof construction, including bearing outer ring, bearing inner race and ball, the two sides of the bearing inner race are provided with extension towards the bearing outer ring direction, there is gap between the extension and the bearing outer ring, the extension side is evenly arranged with several centrifugal flabellums, it is equipped with wind direction water conservancy diversion slope in the periphery of the centrifugal flabellum on the extension, the air-flow that the water conservancy diversion slope guides the centrifugal flabellum to generate is flowed backwards to the gap.Using the structure during bearing inner race rotates, centrifugal flabellum can generate the air-flow outside by center of rotation, flow after by water conservancy diversion slope backwards to gap, so that dust be effectively prevent to enter in the gap of bearing, extend bearing service life.
Description
Technical field
The utility model belongs to technical field of bearings, specifically a kind of motor of dust collector bearing with dustproof construction.
Background technique
Bearing is the components that friction is commonly reduced in shaft, is also required to use bearing in the shaft of dust catcher, and
Dust is relatively more in the use environment of dust catcher.If not doing some dustproof constructions to bearing, will lead to a large amount of dusts into
Enter into bearing, so that bearing ball increased friction, abrasion aggravation or even stuck, so that bearing service life seriously contracts
It is short.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of motor of dust collector bearing with dustproof construction, this kind
Bearing can effectively reduce dust and enter Bearing inner, extend bearing service life.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: one kind has dust-proof
The motor of dust collector bearing of structure, including bearing outer ring, bearing inner race and ball, the two sides of the bearing inner race are towards the axis
Bearing outer-ring direction is provided with extension, has gap between the extension and the bearing outer ring, and the extension side is equal
It is even to be provided with several centrifugal flabellums, wind direction water conservancy diversion slope, the water conservancy diversion are equipped in the periphery of the centrifugal flabellum on the extension
The air-flow that slope guides the centrifugal flabellum to generate is flowed backwards to the gap.The process rotated using the structure in bearing inner race
In, centrifugal flabellum can generate the air-flow outside by center of rotation, flow after by water conservancy diversion slope backwards to gap, thus effectively anti-
Only dust enters in the gap of bearing, extends bearing service life.
In above-mentioned technical proposal, it is preferred that water conservancy diversion slope outer end is flushed with the side of the bearing outer ring.
In above-mentioned technical proposal, it is preferred that be additionally provided with retainer, institute between the bearing outer ring and the bearing inner race
It states and is provided with the ball in retainer.
The utility model compared with prior art, is had the following beneficial effects: and is rotated in bearing inner race using the structure
In the process, centrifugal flabellum can generate the air-flow outside by center of rotation, flow after by water conservancy diversion slope backwards to gap, to have
Effect prevents dust from entering in the gap of bearing, extends bearing service life.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model embodiment.
Fig. 2 is the side view of the utility model embodiment.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing: referring to Fig. 1 to Fig. 2,
A kind of motor of dust collector bearing with dustproof construction, including bearing outer ring 1, bearing inner race 2 and ball 3, in the bearing
The two sides of circle 2 are provided with extension 4 towards 1 direction of bearing outer ring, have between the extension 4 and the bearing outer ring 1
Gap, 4 side of extension are evenly arranged with several centrifugal flabellums 5, in the outer of the centrifugal flabellum 5 on the extension 4
It is equipped with wind direction water conservancy diversion slope 6 week, the air-flow that the water conservancy diversion slope 6 guides the centrifugal flabellum 5 to generate is flowed backwards to the gap.This reality
Applying water conservancy diversion slope in example is arc-shaped transition face, and air-flow is mobile from bearing inner race to bearing outer ring, deviates from axis backward by water conservancy diversion slope
The direction held is mobile, to prevent dust from entering in bearing by gap, extends bearing service life.
In the present embodiment, 6 outer end of water conservancy diversion slope is flushed with the side of the bearing outer ring 1.Can certainly lead
Slope is flowed in the inside of bearing outer ring two sides, and in order to reduce material, and 6 outer end of water conservancy diversion slope and the side of the bearing outer ring 1 are neat
Flat is most saving material.
It is additionally provided with retainer 7 between the bearing outer ring 1 and the bearing inner race 2, is arranged in the retainer 7
State ball 3.
