Abstract

The invention discloses a super-huge-type self-aligning roller bearing roller lifting appliance, and belongs to the technical field of bearing lifting appliances. A clamping arm is provided with a swing arm rotating around the clamping arm; the tail part of the swing arm is provided with tension springs; the other ends of the tension springs are connected with the clamping arm; a handle is fixed on the clamping arm; the top end of the swing arm and the clamping arm are provided with two baffles; when the baffle on the swing arm is at the horizontal position, the baffle on the swing arm and the baffle on the clamping arm are at the same horizontal level; the bottom of the clamping arm is provided with a clamping claw; the opening of the clamping claw can be embedded from the lower end of a roller, and moves upward to the middle of the roller to clamp the roller, and the roller is lifted up. The super-huge-type self-aligning roller bearing roller lifting appliance has the beneficial effects that the roller lifting appliance is used for assembling a sleeve, so that the labor intensity for assembling a sleeve by assembly workers is reduced greatly; the sleeve assembling efficiency of the super-huge-type self-aligning roller bearing is improved.

Description

Oversize self-aligning roller bearing roller suspender

technical fieldoversize self-aligning roller bearing roller suspender, belongs to bearing hoister technical field.

background technologyoversize self-aligning roller bearing, roller weight 40 Kg～60Kg, diameter of phi 150～Φ 200mm, be mainly used in cement machinery Vertical Mill industry, during assembling trap, first a row retainer be placed on inner ring, then another row retainer is inserted in to the corresponding row of inner ring, level is put into cup raceway again, from inner ring ball mouth, pack roller into successively and carry out trap, roller is removed by people, when roller weight reaches 60 Kg, when diameter reaches Φ 200mm, staff cannot remove easily.

summary of the inventionin view of the defect that prior art exists, the object of this invention is to provide a kind of oversize self-aligning roller bearing roller suspender that improves trap efficiency, reduces assembler's trap labour intensity.

For achieving the above object, the technology used in the present invention solution is: oversize self-aligning roller bearing roller suspender, jig arm is provided with the rocking arm rotating around it, at rocking arm afterbody, be provided with extension spring, the extension spring other end connects jig arm, in jig arm, be fixed with handgrip; rocking arm top and jig arm are provided with two baffle plates; the baffle plate when baffle plate on rocking arm is horizontal and in jig arm is on same level line; jig arm bottom is provided with jaw; the opening of jaw can embed from the lower end of roller, and on move to roller middle part and block roller, roller is sling.

Oversize self-aligning roller bearing roller suspender, its beneficial effect is: solve roller weight and when the oversize self-aligning roller bearing assembling of 40 Kg～60Kg, do not rely on staff to remove roller to carry out trap; Use roller suspender to carry out trap, greatly reduce the labour intensity of assembler's trap, improved the efficiency of oversize self-aligning roller bearing trap.

Accompanying drawing explanation

Fig. 1 is the constructional drawing of oversize self-aligning roller bearing roller suspender.

Fig. 1 Reference numeral is as follows: 1, rocking arm, 2, jig arm, 3, jaw, 4, baffle plate, 5, handgrip, 6, extension spring, 7, roller.

The specific embodiment

The constructional drawing of the oversize self-aligning roller bearing roller suspender showing with reference to the accompanying drawings is below described as follows: oversize self-aligning roller bearing roller suspender, jig arm 2 is provided with the rocking arm 1 rotating around it, at rocking arm 1 afterbody, be provided with extension spring 6, extension spring 6 other ends connect jig arm 2, in jig arm 2, be fixed with handgrip 5, rocking arm 1 top and jig arm 2 are provided with two baffle plates 4, baffle plate 4 when the baffle plate 4 on rocking arm 1 is horizontal and in jig arm 2 is on same level line, jig arm 2 bottoms are provided with jaw 3, the opening of jaw 3 can embed from the lower end of roller 7, and on move to roller 7 middle parts and block roller 7, roller 7 is sling.

While using suspender, the opening of jaw 3 embeds from roller 7 lower ends, on jaw 3, move to roller 7 middle parts and block roller 7, roller 7 is sling, now at Action of Gravity Field lower shake-changing arm 1 to lower swing, rely on the baffle plate 4 in rocking arm 1 and jig arm 2 to block roller 7, prevent that roller 7 from toppling over, roller 7 is sling, put to inner ring ball mouth place and upper end, retainer pocket hole; rocking arm 1 lifts under the effect of extension spring 6 spring forces, jaw 3 is displaced downwardly to and grasps handgrip 5 behind roller 7 diameter lower ends and pull out suspender, and roller 7 is in inner ring ball mouth is fallen into retainer pocket hole.

Claims

1. oversize self-aligning roller bearing roller suspender, it is characterized in that: jig arm is provided with the rocking arm rotating around it, at rocking arm afterbody, be provided with extension spring, the extension spring other end connects jig arm, is fixed with handgrip; rocking arm top and jig arm are provided with two baffle plates in jig arm; the baffle plate when baffle plate on rocking arm is horizontal and in jig arm is on same level line, and jig arm bottom is provided with jaw, and the opening of jaw can embed from the lower end of roller; also, move to roller middle part and block roller, roller is sling.
