Abstract
The utility model provides a kind of cantilever shaft support device of single-ended mounting or dismounting, comprises shafting components (as axle, bearing, end cap, seal ring, paper gasket, screw etc.), bearing race, jacking screw, fastening screw trip bolt, spring washer, base.First described shafting components is loaded in bearing race, adjusts bearing play with paper gasket, form cantilevered axle assembly, more described cantilevered axle assembly is installed on base by transition fit seam, locate with fastening screw trip bolt; During dismounting cantilevered axle, unclamp described fastening screw trip bolt, the flange circle tapped hole being screwed into bearing race with jacking screw just can trip out bearing race and whole cantilevered axle assembly.Install and remove maintenance cantilever axle or change bearing all very convenient.
Description
Technical field
The utility model belongs to technical field of mechanical transmission, is specifically related to a kind of cantilever shaft support device of single-ended mounting or dismounting.
Background technique
In mechanical transmission structure, due to spatial structure layout restrictions, often can use cantilevered axle and carry out transferring power or support certain part.For the cantilevered axle needing transferring power, its support is generally be arranged in bearing support by two or more bearing and end cap thereof, and bearing support is arranged on base again, also has bearing support and base to be made of one.If do not have special circumstances, as long as calculate cantilevered axle and be supported with enough strength and stiffness, designing simple load and unload cantilever shaft support device is be relatively easy to.But, due to spatial structure restriction, can only install and remove the occasion of cantilevered axle from one end, if do not designed specified structure, cantilevered axle is very troublesome away from the bearing of mounting or dismounting end and the mounting or dismounting of end cap thereof, so be necessary to design the cantilever shaft support device can installed and removed from one end of axle.
Summary of the invention
From the problem of one end mounting or dismounting cantilevered axle of axle, a kind of cantilever shaft support device of single-ended mounting or dismounting can be the utility model proposes to solve.
The technological scheme that the utility model technical solution problem adopts is, a kind of cantilever shaft support device of single-ended mounting or dismounting, shown in Fig. 1, comprise axle, screw one, end cap one, seal ring one, bearing one, bearing race, jacking screw, bearing two, paper gasket, end cap two, screw two, seal ring two, fastening screw trip bolt, spring washer, base.Be enclosed within the respective step of axle to bearing one and bearing two interference fit, bearing one and bearing two are arranged in the endoporus of bearing race, and with end cap one, screw one axial restraint bearing one, with end cap two, screw two axial restraint bearing two, paper gasket is for adjusting bearing play; Seal ring one is placed between end cap one and axle, and seal ring two is placed between end cap two and axle; The cylinder cylindrical of bearing race is inserted in the endoporus of base, is transition fit between the two, and the flange circle bottom surface of bearing race contacts with the upper surface of base, is fixed on base by bearing race with fastening screw trip bolt, spring washer.
As shown in Figure 2 and Figure 3, the endoporus of bearing race is coaxial with the cylindrical of itself cylinder, and the flange circle bottom surface of bearing race is vertical with cylinder cylindrical; The flange circle of bearing race has 6 uniform through holes, the position circle diameter at described through hole place is equal with the screw hole location circular diameter of base upper surface; Described position circle also has the tapped hole for jack-up cantilevered axle assembly at two diagonal angles.
The invention has the beneficial effects as follows, the occasion of cantilevered axle can only installed and removed from one end of axle, can first by shafting components as axle, bearing, end cap, seal ring etc. are loaded in bearing race, bearing play is adjusted in advance with paper gasket, end cap is fixed with screw axial, form cantilevered axle assembly, more described cantilevered axle assembly is installed on base by transition fit seam, locate with fastening screw trip bolt; During dismounting cantilevered axle, unclamp fastening screw trip bolt, the flange circle tapped hole being screwed into bearing race with jacking screw just can trip out bearing race and whole cantilevered axle assembly.Install and remove maintenance cantilever axle or change bearing all very convenient.
