Description
Technical field
The utility model relates to design bearing manufacturing technology field more particularly to a kind of oiliness bearings.
Background technique
Oiliness bearing is using metal powder as primary raw material, with the sintered body of powder metallurgic method production.Oiliness bearing is non-
Operating condition, lubricating oil is full of its hole, and when operating, axis revolution is generated heat because of friction, and bearing shell thermal expansion reduces hole, then
Lubricating oil overflows, into bearing clearance.After axis stops operating, bearing shell is cooling, and hole restores, and lubricating oil is sucked back into hole again.
Common oiliness bearing is after long-time use, lubricating oil volatilization, and dust can enter bearing, slack-off so as to cause equipment revolving speed,
The problems such as noise increases.Common oiliness bearing is usually sleeve-like configuration, when connecting with other rotatable parts, is also easy hair
It is raw to slip situation.
Utility model content
Technical problem to be solved by the utility model is: the deficiency in order to overcome the prior art, the utility model provides one
Kind lubrication is good, and long service life connect the oiliness bearing for being well not susceptible to slip with other rotatable parts.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of oiliness bearing, including bearing body,
The bearing body is cylindrical-shaped structure and center has axis hole, and the bearing body upper surface is integrally formed with axle journal
Portion, the axis hole run through collar center, and the collar diameter is less than the 1/2 of bearing body diameter, the bearing sheet
Body upper surface is also covered with lubricating cup around collar, and the lubricating cup is L-type cover structure, the oil along bearing body axial cross section
Cup edge bearing body short transverse height is less than collar height, the lubricating cup and bearing body upper surface, collar outer peripheral surface
Between form shoe cream room, grease injection is filled in the shoe cream room, is impregnated with lubricating oil in the grease injection.
In the present solution, combination between lubricating cup and bearing body, by be mounted on collar and lubricating cup upper end other zero
Component provides downward pressure for lubricating cup, is crimped on lubricating cup on bearing body by other components.Grease injection is solid knot
Structure is enclosed in inside lubricating cup after infiltrating lubricating oil, is then crimped on bearing body.In oiliness bearing rotation, grease injection
Interior lubricating oil can be added to bearing body, avoid bearing body after long-term work, lubricant effect caused by lubricating oil volatilizees
Decline and friction risk, the appearance of effective noise reduction function.Simultaneously as the presence of collar, collar protrude from lubricating cup,
Other components can be coated at collar and be crimped on lubricating cup, and the connection of other components and oiliness bearing is reliable.
Further, collar and bearing body upper surface junction are arc transiting surface.
Further, bearing body and collar are iron base sintered body structure made of ferrous based powder metallurgical.
The utility model has the beneficial effects that oiliness bearing provided by the utility model, structure is simple, and design rationally, is led to
The cooperation of lubricating cup and collar is crossed, the connection of oiliness bearing and other components can be convenient for, slip phenomenon is not susceptible to, has simultaneously
Effect ensure that the oil content of oiliness bearing, extend the service life containing bearing.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model optimum embodiment.
1, bearing body 2, axis hole 3, collar 4, lubricating cup 5, grease injection 6, arc transiting surface in figure.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of oiliness bearing as shown in Figure 1 is the utility model optimum embodiment, including bearing body 1.Bearing body
1 and collar 3 be ferrous based powder metallurgical made of iron base sintered body structure.
The bearing body 1 is cylindrical-shaped structure and center has axis hole 2,1 upper surface of the bearing body one
Collar 3 is formed, the axis hole 2 runs through 3 center of collar, and 3 diameter of collar is less than the 1/ of 1 diameter of bearing body
2.Collar 3 and 1 upper surface junction of bearing body are arc transiting surface 6.
1 upper surface of bearing body is also covered with lubricating cup 4 around collar 3, and the lubricating cup 4 is along 1 axis of bearing body
It is L-type cover structure to section, the lubricating cup 4 is less than 3 height of collar, the lubricating cup 4 along 1 short transverse height of bearing body
Shoe cream room is formed between 1 upper surface of bearing body, 3 outer peripheral surface of collar, and grease injection 5 is filled in the shoe cream room, it is described
Lubricating oil is impregnated in grease injection 5.
Combination between lubricating cup 4 and bearing body 1 is by being mounted on other components of 4 upper end of collar 3 and lubricating cup as oil
Cup 4 provides downward pressure and realizes, is crimped on lubricating cup 4 on bearing body 1 by other components.Grease injection 5 is solid knot
Structure is enclosed in inside lubricating cup 4 after infiltrating lubricating oil, is then crimped on bearing body 1.In oiliness bearing rotation, oiling
Lubricating oil in rouge 5 can be added to bearing body 1, avoid bearing body 1 after long-term work, lubrication caused by lubricating oil volatilization
Effect decline and friction risk, the appearance of effective noise reduction function.Simultaneously as the presence of collar 3, collar 3 is to protrude from
Lubricating cup 4, other components can be coated at collar 3 and be crimped on lubricating cup 4, and the connection of other components and oiliness bearing can
It leans on.
The oiliness bearing being designed in this way, structure is simple, and design rationally, by the cooperation of lubricating cup 4 and collar 3, can be convenient for
The connection of oiliness bearing and other components is not susceptible to slip phenomenon, while the oil content of oiliness bearing has been effectively ensured, and prolongs
The service life containing bearing is grown.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
