Abstract
The utility model discloses a hydraulic axial load loading device, which comprises a cross beam, a supporting screw which is fixedly connected with the cross beam and a bearing block, a supporting ring which acts on an end face of an outer ring of a conical roller bearing, and a loading cylinder which is arranged between the supporting ring and the cross beam. By adoption of the structure, the hydraulic axial load loading device can provide a certain axial load for the bearing, the end play of large conical roller bearings which are arranged opposite to each other in pairs under the quantitative preload is conveniently measured by an operator through a measuring tool, the assembling and positioning precision of the bearing and the shaft is guaranteed, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of axial load charger, especially a kind of hydraulic axial load charger that is used for the large-scale taper roll bearing of installing face-to-face in pairs.
Background technology
The large-scale taper roll bearing of installing face-to-face in pairs, it must be to be in the state that a kind of end-play was eliminated and loaded certain axial preload in use.But owing to above-mentioned bearing self size is big, the axial distance of two bearings is far away and requiredly add reasons such as axial load is bigger in advance; Cause preload to be difficult to quantitatively stable the loading; End-play can't accurately be measured, thereby can't guarantee the assembling and positioning precision of bearing and axle.
Summary of the invention
The technical problem that the utility model will solve provides a kind of hydraulic axial load charger; After being installed in it on bearing; This device can provide a certain amount of axial load and be convenient to the staff bearing measures end-play accurately through survey tool, has guaranteed the assembling and positioning precision of bearing with axle.
In order to solve the problems of the technologies described above; The utility model hydraulic axial load charger comprises crossbeam, be fixedly connected the studdle of crossbeam and bearing block, act on the support ring on the taper roll bearing cycle surface and be arranged on support ring and crossbeam between load cylinder; The piston action of said load cylinder is on crossbeam, and the base of this load cylinder is fixed on the support ring.
After adopting such structure; This hydraulic axial load charger can provide a certain amount of axial load and be convenient to the staff bearing measures the play of the large-scale taper roll bearing of installing face-to-face in pairs under quantitative preload accurately through survey tool, guaranteed bearing and axle the assembling and positioning precision, prolonged service life of bearing.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
Fig. 1 is the sketch map of the utility model hydraulic axial load charger.
The specific embodiment
As shown in Figure 1, the utility model hydraulic axial load charger comprises: crossbeam 1, be fixedly connected crossbeam 1 and bearing block 6 studdle 2, act on the support ring 3 on taper roll bearing 5 cycle surfaces and be arranged on support ring 3 and crossbeam 1 between load cylinder 4.The piston 4-1 of said load cylinder 4 acts on the crossbeam 1, and the base 4-2 of this load cylinder 4 is fixed on the support ring 3.
Crossbeam 1 is fixed on the bearing block 6 through studdle 2, and support ring 3 acts on the end face of taper roll bearing 5 outer rings, and load cylinder 4 is used between support ring 3 and crossbeam 1, axial load being provided.During this hydraulic axial load charger work; Hydraulic system provides the oil pressure of certain pressure to make it to produce quantitative axial thrust for load cylinder 4, applies a certain amount of axial load for the large-scale taper roll bearing of installing face-to-face in pairs 5 on the axle 7 through support ring 3, crossbeam 1, studdle 2 and bearing block 6.Under this state; Be convenient to the staff and accurately measure the play of the large-scale taper roll bearing of installing face-to-face in pairs 5 under quantitative preload through survey tool; According to the play of measuring accurately match grinding go out assembling and use spacer ring; Thereby realize the assembling under the bearing precision preload condition, guaranteed the large-scale taper roll bearing of installing face-to-face in pairs 5 and axle 7 assembly precision, prolonged service life of this taper roll bearing 5.
In sum, the content of the utility model is not confined in the above embodiments, and those skilled in the art can propose other embodiment within technological guidance's thought of the utility model, but this embodiment is included within the scope of the utility model.
