Abstract
The utility model provides a self-lubricating bearing, comprising an outer ring, an inner ring and balls. A rolling channel is commonly formed by the outer ring and the inner ring; the ball rolls in the rolling channel; holes are arranged on the wall of the rolling channel formed by the outer ring, and outer lubricating grooves arranged at the wall back side for forming the rolling channel; holes are arranged on the wall of the rolling channel formed by the inner ring, and inner lubricating grooves are arranged at the wall back side for forming the rolling channel; and a solid lubricating agent is placed in the outer lubricating groove and the inner lubricating groove. The self-lubricating bearing provided by the utility model forms the lubricating grooves at the wall back sides of the inner ring and the outer ring, which are used for forming the rolling channels; and the lubricating agent is placed in the lubricating grooves. The holes are arranged on the walls of the rolling channel, so that the solid lubricating agent falls down from the lubricating grooves in the lubricating groove above the ball when the bearing rotates. Therefore, the ball is lubricated, and the lubricated ball falls down the lubricating groove below the ball for collection. The relative position of the lubricating grooves can be changed with the rotation of the bearing, so that the solid lubricating agent is circularly used.
Description
Technical field
The utility model relates to field of bearings, relates in particular to a kind of self oiling bearing.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into two types on rolling bearing and sliding bearing.
Mostly present widely used bearing is rolling bearing, comprises ball bearing and roller bearing.Rolling bearing is exactly that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical component of a kind of precision of the loss of reducing friction.
Because bearing self also is a kind of mechanical devices, though its main friction is rolling friction, can not avoid the wearing and tearing between the mechanical part, bearing self also need be lubricated.Lubricated realize through oiling agent that oiling agent comprises two kinds of fluid lubricant and solid lubricants, fluid lubricant mainly is a lubricant oil; Lubricant oil is easy to use; Cost is low, but the lubricant oil chemical property is unstable, and problems such as rotten take place under high temperature condition easily.Solid lubricant is representative with molybdenum disulfide, stable chemical performance, and lubrication effect is good, but the interpolation of solid lubricant is more complicated than fluid lubricant, lacks the self oiling bearing that uses solid lubricant.
The model utility content
The utility model is intended to propose a kind of self oiling bearing that can be applicable to solid lubricant.
Embodiment according to the utility model proposes a kind of self oiling bearing, comprises outer ring, inner ring and spin; Outer ring and inner ring form raceway jointly, and spin is rolled in raceway, perforate on the wall of outer ring formation raceway; And lubrication groove outside the wall rear side that forms raceway has; Perforate on the wall of inner ring formation raceway, and, place solid lubricant in outer lubrication groove and the lubricating groove at the wall rear openings lubricating groove that forms raceway.
In one embodiment, solid lubricant is a molybdenum disulfide.
In one embodiment, spin is ceramic ball or steel ball.
In one embodiment, the raceway of outer ring and inner ring formation is several ball-type raceways.
The self oiling bearing of the utility model has all formed lubrication groove at the wall rear side that outer ring and inner ring are used to form raceway, places solid lubricant in the lubrication groove.On the wall of raceway, have the hole; When bearing rotated, the solid lubricant in the lubrication groove of spin top fell from lubrication groove, and spin is lubricated; Drop into after lubricated in the lubrication groove of spin below and collect; Along with the rotation of bearing, the relative position of lubrication groove changes, and solid lubricant wherein recycles.
Description of drawings
Fig. 1 has disclosed the structural drawing according to an embodiment's of the utility model self oiling bearing.
Embodiment
With reference to shown in Figure 1, the utility model has disclosed a kind of self oiling bearing 100, and this self oiling bearing 100 comprises outer ring 102, inner ring 104 and spin 106.Outer ring 102 and the inner ring 104 common raceways that form, spin is rolled in raceway.In the embodiment shown in fig. 1, outer ring 102 is several ball-type raceways with the raceway that inner ring 104 forms, and is used for the compartment of terrain and holds several spin 106.Spin 106 ceramic ball or steel ball.Outer ring 102 forms on the wall of raceways and has several holes, and outside the wall rear side that forms raceway has lubrication groove 103.Correspondingly, also have several holes on the wall of inner ring 104 formation raceways, and at the wall rear openings lubricating groove 105 that forms raceway, outer lubrication groove 103 and the lubricating groove 105 interior solid lubricants of placing, in one embodiment, solid lubricant is a molybdenum disulfide.
The working principle of this self oiling bearing is following: self oiling bearing has all formed lubrication groove at the wall rear side that outer ring and inner ring are used to form raceway, places solid lubricant in the lubrication groove, such as molybdenum disulfide.On the wall of raceway, have the hole, when bearing rotated, the relative position of outer ring and inner ring can change; Sometimes the outer ring is positioned at the spin top; Inner ring is positioned at spin below (forwarding the bearing top to), and the outer ring is positioned at the spin below sometimes, and inner ring is positioned at spin top (forwarding the bearing bottom to).The solid lubricant that is positioned in the lubrication groove (possibly be outer lubrication groove, also possibly be lubricating groove) of spin top falls from lubrication groove through the hole, and spin is lubricated, and drops in the lubrication groove below the spin through the hole on the wall of below after lubricated and collects.Along with the rotation of bearing, the relative position of lubrication groove changes, and the lubrication groove that is positioned at the below originally turns to the spin top, and solid lubricant repeats above-mentioned greasing again.So, realized recycling of solid lubricant.
The self oiling bearing of the utility model has all formed lubrication groove at the wall rear side that outer ring and inner ring are used to form raceway, places solid lubricant in the lubrication groove.When bearing rotated, solid lubricant recycled spin is lubricated.
