Abstract
The utility model relates to a kind of axle, disclose a kind of multidiameter shaft, comprise axis body (1), position-arresting disk (6), axis body (1) is provided with the first oil groove (2), second oil groove (4) and gasket groove (3), axis body (1) rear end is provided with position-arresting disk (6), position-arresting disk (6) is circumferentially evenly distributed with 4 compensating grooves (5), the bottom surface of compensating groove (5) is along the axial direction indent of axis body (1), compensating groove (5) bottom surface and axis body (1) outer surface tangent, axis body (1) and the upper all chamferings (8) of position-arresting disk (6) are arc round angle.The utility model effectively can alleviate the internal stress that multidiameter shaft produces after heat treatment, avoid cracking because of heat treatment, it also avoid stress in multidiameter shaft uses concentrate and crack, increase the lubrication to multidiameter shaft simultaneously, substantially prolongs the physical life of multidiameter shaft.
Description
Technical field
The utility model relates to a kind of axle, has particularly related to a kind of multidiameter shaft.
Background technique
Multidiameter shaft of the prior art, the diameter change between position-arresting disk and axis body is sudden change formula.Although this multidiameter shaft is convenient to manufacturing, position-arresting disk and axis body joint easily produce stress and concentrate, and form crackle, cause whole axle to lose efficacy.Multidiameter shaft after the heat treatment simultaneously, the change of internal stress can occur, easily crack on axle surface.Some is applied in rugged environment simultaneously, as the multidiameter shaft be applied in mining machinery can touch more dusts, if do not have enough frictions, greatly can reduce the working life of axle.
Summary of the invention
The utility model is connected the shortcoming easily producing stress and concentrate with axis body for multidiameter shaft lack of lubrication of the prior art, position-arresting disk, provide a kind of new multidiameter shaft.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of multidiameter shaft, comprise axis body, position-arresting disk, axis body is provided with the first oil groove, the second oil groove and gasket groove, axis body rear end is provided with position-arresting disk, position-arresting disk is circumferentially evenly distributed with 4 compensating grooves, the bottom surface of compensating groove along the axial direction indent of axle, compensating groove bottom surface and axis body outer surface tangent, on axis body and position-arresting disk, all chamferings are arc round angle.By using oil lubrication to the first oil groove and the second oil groove, can reduce the wearing and tearing of axle and the cooperation of other parts, gasket groove upper casing installs packing ring in addition, also can reduce wear, and reinforces the matching relationship of axle and other parts.Compensating groove on position-arresting disk can be avoided producing stress at position-arresting disk and change place of axis body diameter and concentrate.On axis body and position-arresting disk, all chamferings are arc round angles, can the internal stress that produces after the heat treatment of release shaft.
As preferably, axis body rear end axially has threaded connection hole.In addition threaded connection hole can make can better be connected between axle with other parts to coordinate and fix.
The utility model, owing to have employed above technological scheme, had both effectively alleviated the internal stress that multidiameter shaft produces after heat treatment, avoided cracking because of heat treatment, it also avoid multidiameter shaft in use stress concentrate and crack.Oil groove is set on axis body simultaneously, increases the lubrication to multidiameter shaft, substantially prolongs the physical life of multidiameter shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The toponym that in accompanying drawing, each number designation refers to is as follows: 1-axis body, the 2-the first oil groove, 3-gasket groove, the 4-the second oil groove, 5-compensating groove, 6-position-arresting disk, 7-tapped hole, 8-chamfering.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
A kind of multidiameter shaft, comprise axis body 1, position-arresting disk 6, axis body 1 is provided with the first oil groove 2, second oil groove 4 and gasket groove 3, axis body 1 rear end is provided with position-arresting disk 6, position-arresting disk 6 is circumferentially evenly distributed with 4 compensating grooves 5, the bottom surface of compensating groove 5 along the axial direction indent of axis body 1, compensating groove 5 bottom surface and axis body 1 outer surface tangent, on axis body 1 and position-arresting disk 6, all chamferings 8 are arc round angle.By using oil lubrication to the first oil groove 2 and the second oil groove 4, can reduce the wearing and tearing of axle and the cooperation of other parts, gasket groove 3 upper casing installs packing ring in addition, also can reduce wear, and reinforces the matching relationship of multidiameter shaft and other parts.Compensating groove 5 on position-arresting disk 6 can be avoided producing stress at position-arresting disk 6 and change place of axis body 1 diameter and concentrate.On axis body 1 and position-arresting disk 6, all chamferings are arc round angles, can discharge the internal stress that multidiameter shaft produces after the heat treatment.
Axis body 1 rear end axially has threaded connection hole 7.In addition threaded connection hole 7 can make can better be connected between multidiameter shaft with other parts to coordinate and fix.
The utility model, owing to have employed above technological scheme, had both effectively alleviated the internal stress that multidiameter shaft produces after heat treatment, avoided cracking because of heat treatment, it also avoid multidiameter shaft in use stress concentrate and crack.Oil groove is set on axis body 1 simultaneously, increases the lubrication to multidiameter shaft, substantially prolongs the physical life of multidiameter shaft.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Claims (2)
