Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 shows the structural representation of shaft bearing replacer of the present utility model, in conjunction with see Fig. 1 to Fig. 2, as can be seen from the figure, the shaft bearing replacer of the present embodiment comprises stiff end 10 and force-applying piece 20, stiff end 10 and force-applying piece 20 are oppositely arranged, and force-applying piece 20 is connected on stiff end 10 by coupling assembling.Stiff end 10 is provided with the shoulder hole 11 for holding bearing, the cascaded surface of shoulder hole 11 and the end face of bearing suitable, diameter holes and the bearings mounted axle of shoulder hole 11 are suitable.Force-applying piece 20 is arranged movably, and has primary importance and the second place, and when force-applying piece 20 is positioned at primary importance, the first end of force-applying piece 20 is positioned at shoulder hole.When force-applying piece 20 is positioned at the second place, the second end of force-applying piece 20 is away from shoulder hole.
The shaft bearing replacer of the present embodiment, is fixed by stiff end 10 pairs of bearings, and applies external force by the axial end of force-applying piece 20 to the axle being provided with bearing, makes axle and bearing generation relative motion, and then bearing is departed from from axle.Adopt the shaft bearing replacer of the present embodiment, it is stressed that axle is always end face entirety in the process of dismounting, and uniform force, and this dismounting mode convenient and swift and not fragile axle and bearing, is convenient to reusing of axle and bearing.
As shown in Figure 3 to Figure 4, for convenience of coordinating of stiff end 10 and bearing, the stiff end 10 of the present embodiment comprises two clamping elements be oppositely arranged 12.Each clamping element 12 is provided with end difference, and the inwall of each end difference is semicircular arcwall.When the split of two clamping elements 12 together time, the common combination of two end differences forms the shoulder hole 11 of stiff end 10.For ease of the connection between clamping element 12, the profile of clamping element 12 is preferably the semicircle with end difference adaptation, and semicircular two ends are provided with outward extending connecting portion 13.When after the split together of two clamping elements 12, the connecting portion 13 two clamping elements 12 being positioned at homonymy also can fit together, and now links together two connecting portions 13 to realize connection between two clamping elements 12 and fixing by connectors such as bolt and nuts.
The stiff end 10 of this connected mode is adopted to coordinate with bearing easily.When there being the bearing needing dismounting, can by axial outer mobile one end distance, make that there is between bearing and gantry-shaped steel certain distance, then clamping element 12 is placed between bearing and gantry-shaped steel, two of the end difference of clamping element 12 sections of sidewalls and axle and bearing are fitted respectively, after being connected by two clamping elements 12, namely can form axle coordinate with the aperture of shoulder hole 11, bearing coordinates with the macropore of shoulder hole 11 and bearing surface is fitted in the fit system on the end face of shoulder hole 11.Preferably, the wall thickness of stiff end should be less than 8mm, is less than 8mm to make the distance between bearing and shaped steel.Such setting can be beneficial to the taking-up of bearing, makes the advantage of shaft bearing replacer reach maximization.
After stiff end 10 is fixed on bearing end place, the end face namely by force-applying piece 20 pairs of axles applies external force.Force-applying piece 20 preferably in column, and the first end of force-applying piece 20 towards axle end face and aim at the center of circle.For increasing the force of force-applying piece 20 pairs of axle heads, preferably the first end of force-applying piece 20 can be arranged taper, to reduce the contact area between force-applying piece 20 and axle head.Connecting rod 32 it should be noted that the line of the first end of two connecting rods 32 should through the center of circle of shoulder hole 11 in use, and such arranging can facilitate the center of the aligning axle head of force section.
In order to what make that force-applying piece 20 can be stable, external force is applied to axle head, also force-applying piece 20 is connected on stiff end 10 by coupling assembling.In the present embodiment, coupling assembling comprises two connecting rods, 32, gripper shoe 31 and multiple pressing plate.The first end of two connecting rods 32 is connected on a clamping element 12, and the second end of two connecting rods 32 is connected to the two ends of gripper shoe 31, to make relatively between gripper shoe 31 with stiff end 10 to arrange regularly.The middle part of force-applying piece 20 is movably located in the middle part of gripper shoe 31, can move between the first position and the second position to make force-applying piece 20.In order to make the connection between connecting rod 32 and gripper shoe 31 more fastening and flexible, the breach for holding connecting rod 32 second end is all offered at the two ends of gripper shoe 31, the bearing of trend of breach is the bearing of trend along gripper shoe 31, and and on stiff end 10 to gripper shoe 31 direction through gripper shoe 31.Adopt the fit system of breach and connecting rod 32, the position of connecting rod 32 in breach can be adjusted arbitrarily.When namely by fixtures such as nuts, connecting rod 32 being fixed in gripper shoe 31 behind the position of adjusting connecting rod 32.For attaching nut, connecting rod 32 on its outer surface society is provided with external screw thread.Correspondingly, the first end of connecting rod 32 is fixed on clamping element 12 by nut, and breach defines accommodation hole.
For the bonding strength of reinforced company's extension bar 32 in gripper shoe 31, also use second end of pressing plate to connecting rod 32 in the present embodiment and carry out auxiliary fixing.Pressing plate in the present embodiment is concave structure, comprises a pressing plate main body and is connected to two auxiliary plates at pressing plate main body two ends, two auxiliary plates all vertical with pressing plate main body and two auxiliary plates be oppositely arranged, make a common formation holding tank between auxiliary plate and pressing plate main body.Pressing plate in use, the outer surface of the medial surface of auxiliary plate and gripper shoe 31 is utilized to match, pressing plate main body matches with the surface away from stiff end 10 of gripper shoe 31, and pressing plate offers the through hole for wearing connecting rod 32, and nut top is pressed in pressing plate main body and deviates from the back side of support bar.For obtaining better fixed effect, pressing plate can be provided with in the both sides of gripper shoe 31 connecting rod 32 is fixed.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
