Description

A kind of conical roller bearing ring

Technical field

The utility model is related to technical field of bearings, specially a kind of conical roller bearing ring.

Background technology

Taper roll bearing belongs to divergence type bearing, and the inside and outside circle of bearing is respectively provided with tapered raceway.The class bearing is by being filled The columns of roller is divided into the different structural shape such as single-row, biserial and four-row tapered roller bearing.Single-row tapered roller bearing can To bear radial load and single direction axial load.When bearing bears radial load, it will produce an axial thrust load, institute Balanced with needing another to bear the bearing of opposite direction axial force.Single-row tapered roller bearing bears axial load Ability depends on contact angle, i.e. outer ring raceway angle, and angle is bigger, and axial load ability is also bigger.Used in taper roll bearing It is single-row tapered roller bearing that amount is most.In the front-wheel hub of car, the double-row conical bearing of small size has been used. Four-row tapered roller bearing is used in the heavy-duty machines such as Large Scale Cold, hot-rolling mill.

Taper roll bearing inevitably needs to use its supporting lasso to carry out overall assembling in assembling process, existing Some conical roller bearing rings do not have rounding to design, the bump injury for making it that lasso occur in assembling process, influence axle The assembly precision for holding, taper roll bearing is completed during use in assembling, and running noises are larger, does not meet mechanical movement reduction The requirement of noise, in use due to its sealing problem, external dust enters Bearing inner to taper roll bearing, influence The using effect of bearing, therefore, come into operation we have proposed a kind of conical roller bearing ring, to solve the above problems.

Utility model content

The purpose of this utility model is to provide a kind of conical roller bearing ring, to solve to be proposed in above-mentioned background technology Existing conical roller bearing ring there is no rounding to design, the bump injury for making it that lasso occur in assembling process, shadow The assembly precision of bearing is rung, in use due to its sealing problem, external dust enters in bearing taper roll bearing Portion, influences the problem of the using effect of bearing.

To achieve the above object, the utility model provides following technical scheme：A kind of conical roller bearing ring, including it is outer Lasso and inside race, are provided with oil filler point in the outer circumferential walls of the outer collar, the left and right sides of the inside race is equipped with baffle plate, Raceway is connected between baffle plate described in two groups, the outer circumferential walls of the raceway are provided with integrally formed oil duct, the inside race Inner chamber place placed in the middle is provided with pin shaft hole, and the upper and lower ends of the pin shaft hole are arranged with seal groove, the edge corner of the inside race Place is provided with circular arc chamfering.

Preferably, the outer collar and inside race are poured into a mould using high-carbon-chromium bearing steel by quenching and tempering process one Form.

Preferably, the coning angle of the outer collar is between 10-19 °, and the small end face inner chamber of outer collar is provided with and inner sleeve The annular groove that small end face baffle plate on circle is adapted.

Preferably, the oil duct is formed using shaped profile turning cutter one turning, and the depth of oil duct is 0.4-0.6 millimeters.

Compared with prior art, the beneficial effects of the utility model are：The device is by oil filler point to circumference roller bearing Inside addition lubricant grease, reduces the coefficient of friction of taper roll bearing, while using the design of rounding, reducing bearing ring Bump injury in mill processing and assembling process, so as to reduce the vibration values of bearing finished products, the coning angle of outer collar is designed to 10- 19 °, synergy of the bearing to load and radial load can be simultaneously born, using high-carbon-chromium bearing steel one cast Outer collar and inside race, make it have high and uniform hardness, and good wearability improves its contact fatigue.

Brief description of the drawings

Fig. 1 is the utility model structural representation；

Fig. 2 is the utility model inside race A-A to profile.

In figure：1 outer collar, 2 inside races, 21 pin shaft holes, 22 seal grooves, 23 circular arc chamferings, 3 oil filler points, 4 oil ducts, 5 rollings Road, 6 baffle plates.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of conical roller bearing ring, including overcoat Circle 1 and inside race 2, are provided with oil filler point 3 in the outer circumferential walls of the outer collar 1, the left and right sides of the inside race 2 is equipped with gear Plate 6, is connected with raceway 5 between baffle plate 6 described in two groups, the outer circumferential walls of the raceway 5 are provided with integrally formed oil duct 4, described The inner chamber place placed in the middle of inside race 2 is provided with pin shaft hole 21, and the upper and lower ends of the pin shaft hole 21 are arranged with seal groove 22, described interior Circular arc chamfering 23 is provided with the edge corner of lasso 2.

Wherein, the outer collar 1 and inside race 2 are poured into a mould using high-carbon-chromium bearing steel by quenching and tempering process one Form, the coning angle of the outer collar 1 between 10-19 °, and outer collar 1 small end face inner chamber be provided with it is small on inside race 2 The annular groove that end face baffle 6 is adapted, the oil duct 4 is formed using shaped profile turning cutter one turning, and the depth of oil duct 4 is 0.4-0.6 millimeters.

Operation principle：By oil filler point 3 to adding lubricant grease inside taper roll bearing, and will be lubricated using oil duct 4 Grease is dispersed into each position of taper roll bearing, reduces the coefficient of friction of taper roll bearing operation, in inside race 2 Chamber sets seal groove 22, and seal is plugged into seal groove 22, strengthens the sealing of bearing, prevents external dust from entering into axle Inside is held, the using effect of bearing is influenceed, the edge corner of inside race 2 is designed to the structure of circular arc chamfering 23, can effectively subtracted Bump injury of the small bearing ring in mill processing and assembling process, reduces the vibration values of bearing finished products, while by the circle of outer collar 1 Cone angle design can simultaneously bear synergy of the bearing to load and radial load into 10-19 °, and the apparatus structure is simple, if Meter is reasonable, with very strong practicality.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out various changes in the case where principle of the present utility model and spirit is not departed from, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
