Abstract

The invention relates to a flanged joint bearing installation device which comprises a pressing head and a guide shaft sleeve. The pressing head is of a hollow structure, a positioning shaft is arranged on the guide shaft sleeve, and the pressing head is in clearance fit with the positioning shaft on the guide shaft sleeve through a center hole. The upper end of the pressing head is a plane, and the lower end of the pressing head is provided with a V-shaped annular pointed end with a downward pointed end body. The diameter of the V-shaped annular pointed end is not smaller than that of a V-shaped annular groove on the outer circle of a joint bearing. A base of the guide shaft sleeve is provided with a V-shaped annular pointed end which is identical with the V-shaped annular pointed end, with the downward pointed end body, on the pressing head in size and symmetric with the V-shaped annular pointed end, with the downward pointed end body, on the pressing head in position. The flanged joint bearing installation device overcomes the difficulty that the joint bearing is likely to deviate and stagger in the flanging process, and solves the problem that flanging amount is not enough, accordingly pressing of the joint bearing is not sufficient and the bearing falls off.

Description

Flange oscillating bearing erecting device

Technical field

The present invention relates to a kind of oscillating bearing erecting device, being particularly suited for outer shroud needs the oscillating bearing of flange to install.

Background technology

Oscillating bearing major function is spherical transmission, in use can rotate around axial line, oscillating motion, banking motion, improve the stationarity between connector, there is Self-aligning, high-mechanic, the function such as non-maintaining. Oscillating bearing installation quality directly affects service life and the safety of whole system. Outer shroud is needed to the oscillating bearing of flange, except being assembled on bearing mounting base according to the requirement of bearing, further relate to the compression of flange. In existing mounting means, after adopting compaction tool that bearing is pressed into bearing block, outward flanging after making outer race deform by external force, it is stuck in the chamfering that bearing block edge is arranged, it is achieved substrate hold-down function; But, this mode does not account for the flange amount of outer race and the matching relationship of the chamfering of bearing block, thus it is insufficient to cause that bearing flange compresses, oscillating bearing is loose or dislocation from bearing mounting base, or owing to oscillating bearing occurs that in turn-up process skew and dislocation cause the problems such as oscillating bearing is unsmooth.

Summary of the invention

It is an object of the invention to provide a kind of flange oscillating bearing erecting device, described device has location and guide function, it is achieved the advantages such as oscillating bearing is installed without deflection, flange fully compression, this device is easy to use, simple to operate simultaneously, can improve assembling quality.

The technical scheme is that flange oscillating bearing erecting device includes pressure head 1, guides sleeve 2, pressure head is hollow structure, leading axle puts and is provided with locating shaft, pressure head by centre bore with the locating shaft matched in clearance guided on sleeve, pressure head can move on locating shaft, described pressure head upper end is plane, presses for forcing press, lower end is provided with the V-arrangement ringed tip of pointed end, the angle of described V-arrangement ringed tip is A+B, wherein A is the angle of V-arrangement ringed tip lateral surface and vertical direction, its angle should meet C < A < C+30 ��, C is the chamfering of bearing mounting base, B is the angle of V-arrangement tip medial surface and vertical direction, its angle value is the half of the angle of oscillating bearing outer shroud V-arrangement annular recess, the diameter of described V-arrangement ringed tip is not less than the diameter of oscillating bearing outer shroud V-arrangement annular recess, the described base guiding sleeve is provided with identical with the V-ring shape tip size of the pointed end on pressure head, the tip of positional symmetry V-arrangement ringed tip upward.The diameter 0.3-0.8mm bigger than the diameter of oscillating bearing outer shroud V-arrangement annular recess of the V-arrangement ringed tip of described pressure head lower end. The chamfering of described bearing mounting base is 45 degree.

The present invention is in use, first just outer shroud both ends of the surface there is the oscillating bearing of V-ring connected in star to be arranged on the bearing block with chamfering, it is then placed within guiding on the base of axle sleeve, the V-arrangement annular recess arranged on the outer shroud lower surface of oscillating bearing and the tip on base V-ring shape nib contacts upward, then pressure head is arranged on the locating shaft that leading axle puts, mobile pressure head is until the V-arrangement ringed tip of base pointed end contacts with the V-ring shape groove arranged on the outer shroud upper surface of oscillating bearing, stable pressure is applied in pressure head plane one end, realize oscillating bearing outer shroud V-arrangement annular recess to deform upon, outer race flange and bearing block chamfering are close to effect, reach the purpose that bearing is installed. for compressing fully after ensureing flange, measuring the maximum gauge installing posterior joint bearing outer-loop, generally, swell about 15% is best. the present invention is provided with V-arrangement ringed tip on pressure head and guiding sleeve, by to the appropriate design of V-ring shape tip angle and the diameter increasing V-arrangement ringed tip, add the requirement press-fiting rear diameter, achieve the function of flange oscillating bearing outward flanging, ensure flange amount, compress fully after making oscillating bearing flange. overcome oscillating bearing and the difficulty of skew and dislocation easily occurs in turn-up process, solve because of flange amount that to cause that oscillating bearing compresses not insufficient, and then cause the problem that bearing comes off.
