Lifting appliance for lifting bearing with inseparable inner and outer rings

Abstract

The invention relates to a bearing lifting appliance, in particular to a lifting appliance for lifting a bearing with inseparable inner and outer rings. The lifting appliance comprises two semicircular hoops for clamping the bearing; the radii of the two semicircular hoops are less than the radius of the outer ring of the bearing; one ends of the two semicircular hoops are hinged by a hinge pin; the other ends of the two semicircular hoops are connected by a bolt; three lifting points are uniformly arranged on the outer peripheral surfaces of the two semicircular hoops; ring-shaped copper plates are embedded on the inner peripheral surfaces of the two semicircular hoops for protecting the bearing from being damaged; and ball lifting bolts capable of being sunk into a bearing oil groove are uniformly arranged on the semicircular hoops and are used for carrying out lifting protection. According to the bearing lifting appliance, the two semicircular hoops are adopted; the rapid and convenient clamping of the lifting appliance is implemented and the labor intensity is reduced. The ring-shaped copper plates are embedded in the two semicircular hoops, so that a steel plate in the lifting appliance is avoided being directly contacted with the bearing and the bearing is effectively protected. According to the bearing lifting appliance, the outer ring of the bearing is directly suspended by a friction force generated by surrounding the outer ring of the bearing, so that the interference of the lifting appliance to the assembly of the inner ring of the bearing is avoided.

Description

technical field [0001] The invention relates to a bearing sling, in particular to a sling for lifting a bearing whose inner and outer rings cannot be disengaged. Background technique [0002] Generally, medium and large spherical roller bearings, deep groove ball bearings, angular contact ball bearings and other bearings need to be hoisted horizontally when they are assembled or transported, that is, hoisted along the axial direction of the bearing. , resulting in difficulty in hoisting and potential safety hazards. [0003] The existing bearing sling usually uses flexible slings to bind the inner and outer rings of the bearing to achieve horizontal lifting. The disadvantage is that the inner ring of the bearing needs to be wound with slings. not available. Therefore, a new sling is needed to solve the existing difficulties in hoisting, thereby avoiding the interference of the sling to the assembly of the inner ring of the bearing.

[0002] Generally, medium and large spherical roller bearings, deep groove ball bearings, angular contact ball bearings and other bearings need to be hoisted horizontally when they are assembled or transferred, that is, hoisted along the axial direction of the bearing. , resulting in difficulty in hoisting and potential safety hazards

[0003] The existing bearing sling usually uses flexible slings to bind the inner and outer rings of the bearing to achieve horizontal lifting. The disadvantage is that the inner ring of the bearing needs to be wound with slings. Not available

Therefore, a new sling is needed to solve the existing hoisting difficulties, thereby avoiding the interference of the sling on the assembly of the inner ring of the bearing
