Abstract
The invention discloses a supporting device for a guiding wheel. The supporting device comprises a hub (9). A sleeve (1) is sleeved with the hub (9). A center shaft (3) and a plurality of bearings (8) are installed in the sleeve (1). The center shaft (3) is sleeved with the bearings (8). The center shaft (3) is of a bilateral-symmetry structure. The two ends of the center shaft (3) are respectively provided with two step surfaces. The two first-level step surfaces (4) located on the inner side are respectively sleeved with one bearing (8). The two second-level steps (7) located on the outer side are respectively provided with a locking nut (2) compressing the corresponding bearing (8). The supporting device for the guiding wheel has the advantages of being long in service life, flexible in running during movement, reliable in performance and easy to maintain, and reducing the manufacturing cost and the maintenance cost.
Description
Technical field
The present invention relates to the bearing device of a kind of guide wheel device, particularly a kind of upper saw pulley.
Background technique
Upper saw pulley, for to soft pipeline or steel wire, the direction guiding in the linear object moving process of the softwares such as nylon rope.Upper saw pulley is with pulley structure, and in some project or product, upper saw pulley can play labour-saving effect.
Excavator guide pulley is at excavator in straight line moving process, and guide wheel shaft mainly bears radial effect power; When turning, walker active force makes guide wheel shaft produce certain axial thrust load, and radius of turn is less, axial thrust load is larger, and the direction of axial thrust load also changes with the change of turn direction, causes upper saw pulley bearing device often to damage, and when support device is repaired, the maintenance of upper saw pulley bearing device difficulty or ease, and maintenance rear support device is not long working life, has increased manufacture cost and maintenance cost.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of and go slick, reliable performance, the bearing device of the upper saw pulley of maintenance for ease of maintenaince.
Object of the present invention is achieved through the following technical solutions: a kind of bearing device of upper saw pulley, and it comprises wheel hub, and in wheel hub, cover has sleeve, and central shaft and multiple bearing are housed in sleeve, and bearing housing is contained on central shaft.
Described central shaft is symmetrical structure, and the two ends of central shaft are equipped with two step surfaces, on the one-level step surface that two are positioned at inner side, is all respectively set with a bearing, in the two stage steps that two are positioned at outside, the locking nut of a compression bearing is all installed.
Described sleeve and wheel hub are transition fit.
Between described locking nut and bearing, seal washer is installed.
On the two stage steps face of described central shaft, offer outside thread.
The present invention has the following advantages: guide wheel device of the present invention, there is long service life, and when mobile, go slick, reliable performance, and for ease of maintenaince maintenance, reduced and manufactured cost and maintenance cost.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
The structural representation of axle centered by Fig. 2;
In figure, 1-sleeve, 2-locking nut, 3-central shaft, 4-one-level step surface, 5-seal washer, 6-outside thread, 7-two stage steps face, 8-bearing, 9-wheel hub.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of bearing device of upper saw pulley, it comprises wheel hub 9, and in wheel hub 9, cover has sleeve 1, and central shaft 3 and multiple bearing 8 are housed in sleeve 1, and bearing 8 is sleeved on central shaft 3.Central shaft 3 is symmetrical structure, central shaft 3 is provided with three step surfaces, the each suit in both sides one bearing 8 on one-level step surface 4, bearing 8 one end will withstand on step surface end face, in two stage steps, 7 both sides are provided with a locking nut 2, and on two stage steps face, 7 offer outside thread 6, between locking nut 2 and bearing 8, seal washer 5 are installed, seal washer 5 is plastic cement material, tightens locking nut 2 and is close to seal washer 5.
