Problems solved by technology

[0003] However, there are double bearings in the same part of some mechanical equipment. Since the distance between the two bearings is small, and the two bearings must face each other to be taken out, the existing bearing remover cannot take out the bearings.

Embodiment 1

[0013] see Figure 1-2 , a multi-functional two-way hydraulic bearing remover, which includes a bracket 1, two adjustment grooves are respectively opened on the edges of the two sides of the bracket 1, and movable struts 2 are arranged in the adjustment grooves, and each independent movable strut 2. The upper adjustment nut 3 and the lower adjustment nut 4 are fixed on the support 1 by clamping and fitting with the upper adjustment nut 3 and the lower adjustment nut 4. A double-acting hydraulic cylinder 5 is fixed at the center of the middle part of the support 1. The piston rod of the double-acting hydraulic cylinder 5 The end part is connected with the taper pin 9 through threaded coupling. The double-acting hydraulic cylinder 5 is supplied with oil by the hydraulic pump 7, and the direction is changed through the manual reversing valve 6. The outside of the taper pin 9 is provided with The adjusting taper sleeve 8 that fits with it.

[0014] The adjustment taper sleeve 8 i...

Embodiment 2

[0017] 1. Extend the adjusting taper sleeve 8 together with the taper pin 9 into the inner ring of the bearing 11 from the direction where the bearing is to be taken out, and at the same time adjust the relative position between the taper sleeve 8 and the taper pin 9 so that the adjusting taper sleeve 8 expands and the lower end protrudes slightly The inside of the inner ring of the bearing 11 is fully attached to the inner ring of the bearing.

[0018] 2. Adjust the position of the movable support 2 to make it in a suitable position and support height, and then fix and adjust the upper adjustment nut 3 and the lower adjustment nut 4.

[0019] 3. Using the hydraulic pump 7, through the manual reversing valve 6, the hydraulic oil flows in from the A port of the hydraulic cylinder 5 and flows out from the B port, and the plunger moves upward to pull out the bearing.

[0020] The taper sleeve 8 can be replaced and adjusted according to the inner diameters of different bearings to...

Abstract

The invention discloses a multifunctional bidirectional hydraulic bearing puller which comprises a support. The two side edges of the support are each provided with two adjusting grooves, movable supporting columns are arranged in the adjusting grooves, each independent movable supporting column is clamped and fixed to the support through an upper adjusting nut and a lower adjusting nut in screw fit with the corresponding movable supporting column, a double-acting hydraulic cylinder is fixed to the middle circle center of the support, the end of a piston rod of the double-acting hydraulic cylinder is connected with a push pin in a threaded connecting matching mode, a hydraulic pump supplies oil to the double-acting hydraulic cylinder, the direction is changed through a manual reversing valve, and an adjusting conical sleeve matched with the pull pin in a sleeving mode is arranged outside the pull pin. On the premise of not damaging a bearing or equipment, the bearing can be dismounted from a component effectively, and meanwhile an outer ring fixed bearing of a commonly used size can be dismounted under the condition of replacing few components.

Description

technical field [0001] The invention relates to the field of mechanical processing and manufacturing, in particular to a multifunctional two-way hydraulic bearing remover, which is a bearing remover for removing a bearing whose outer ring is fixed on a mechanical component. Background technique [0002] For the disassembly of bearings with a fixed outer ring, there are generally two types of existing disassembly tools, one is the "supporting plate type", that is, the stretching rod with the supporting plate passes through the inner ring on the other side of the direction where the bearing is to be taken out. , the pallet is stuck on one end of the bearing, and the bearing is pulled out at the other end by means of threaded screw, hydraulic pressure, worm gear, etc.; the second is the "three-jaw pull-hook type", that is, the elastic three-jaws are closed and pulled out from the bearing. The direction to be taken out extends to the other end of the bearing, and the three-jaw p...
