Description

A kind of bearing inner race
[technical field]
The utility model relates to the technical field of bearing, in particular to a kind of technical field of bearing inner race.
[background technique]
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced Coefficient of friction in its motion process, and guarantee its rotating accuracy.Bearing is used in mechanical connection, so its environment phase Pair meeting it is poor, while bearing is after a protracted use, and inner ring and outer ring will appear stuck phenomenon.Bearing does not moisten for a long time Cunning can shorten the service life of bearing.
[utility model content]
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, propose a kind of bearing inner race, by newly-increased Tank filler sleeve and oil-through-hole open up U-shaped sulculus on the baltimore groove raceway of bearing inner ring to facilitate bearing to be lubricated, and increase Lubricate area, be bearing inner and outer ring between be not easy out dead, and increase the physical life of bearing.
To achieve the above object, the utility model proposes a kind of bearing inner races, including oil-through-hole, tank filler sleeve, baltimore groove Raceway, U-shaped sulculus, the bearing inner race are provided with 8~15 tank filler sleeves in the axial direction, and the bearing inner race is provided with 8 radially ~15 oil-through-holes, the tank filler sleeve are connected with oil-through-hole, and baltimore groove raceway is provided on the bearing inner race outer wall, described recessed U-shaped sulculus is provided in the axial direction in shape trough roller road.
Preferably, the oil-through-hole of the bearing inner race radially.
Preferably, the tank filler sleeve is identical as oil-through-hole quantity, the tank filler sleeve is equal with the radius of oil-through-hole, favorably Enter bearing in wheel lubricating oil.
It is threaded with sealing-plug as the preferred tank filler sleeve, dust can be prevented to enter bearing, extend making for rod With the service life in service life and bearing.
The utility model has the beneficial effects that compared with prior art, a kind of bearing inner race provided by the utility model, structure Rationally, convenient that bearing is lubricated, reduce bearing inner race and outer ring it is stuck fall the case where, increase roller uses the longevity Life, while also increasing the service life of bearing.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is the axial sectional view schematic diagram of the utility model bearing inner race;
Fig. 2 is the radial partial schematic sectional view of the utility model bearing inner race.
In figure: 1- oil-through-hole, 2- tank filler sleeve, 3- baltimore groove raceway, 4-U shape sulculus.
[specific embodiment]
Refering to fig. 1 and Fig. 2, the utility model embodiment provides a kind of bearing inner race, including oil-through-hole 1, tank filler sleeve 2, recessed Shape trough roller road 3, U-shaped sulculus 4, the bearing inner race are provided with 8~15 tank filler sleeves 2 in the axial direction, and the bearing inner race is in radial direction On be provided with 8~15 oil-through-holes 1, the tank filler sleeve 2 is connected with oil-through-hole 1, is provided with baltimore groove on the bearing inner race outer wall Raceway 3 is provided with U shape sulculus 4 in the axial direction of the baltimore groove raceway 3, and the oil-through-hole 1 of the bearing inner race radially is through-hole, The tank filler sleeve 2 is identical as 1 quantity of oil-through-hole, and the tank filler sleeve 2 is equal with the radius of oil-through-hole 1, and 2 screw thread of tank filler sleeve connects It is connected to sealing-plug.
Utility model works process:
During the work time, the bearing inner race is provided with 10 tank filler sleeves to a kind of bearing inner race of the utility model in the axial direction 2, the bearing inner race is provided with 10 oil-through-holes 1 radially, and the tank filler sleeve 2 is connected with oil-through-hole 1, in the bearing It is provided with baltimore groove raceway 3 on ring outer wall, U-shaped sulculus 4, the tank filler sleeve 2 and logical oil are provided in the axial direction of the baltimore groove raceway 3 1 quantity of hole is identical, and the tank filler sleeve 2 is equal with the radius of oil-through-hole 1, is conducive to lubricating oil and enters in bearing, the tank filler sleeve 2 are threaded with sealing-plug, dust can be prevented to enter in bearing, extend bearing service life.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modification, equivalent replacement or improvement etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
