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
The present invention relates to a kind of bearing hoister, particularly a kind of suspender that is used to lift the bearing that Internal and external cycle can not throw off.
Background technology
When bearings such as general medium-and-large-sized self-aligning roller bearing, deep groove ball bearing, angular contact ball bearing assemblings or transhipment, need the level lifting to place, promptly along bearing axle to lifting; But because of the bearing enclose end face should not be provided with the hole for hoist position; Therefore, cause the lifting difficulty, and have potential safety hazard.
Existing bearing hoister adopts flexible suspender belt to be banded in to be used on the bearing enclose lifting of realization level usually, and its shortcoming is exactly, needs the winding suspender belt on the bearing inner ring, and when requiring the assembling of bearing inner ring and axle journal fit system, this suspender can't use.Therefore, need a kind of new suspender, solve the difficulty of existing lifting, thereby avoided the interference of suspender the bearing inner ring assembling.
Summary of the invention
The technical matters that the present invention will solve provides a kind of and had not only made things convenient for the lifting of bearing safety but also guaranteed that injury-free being used to of bearing lifts the suspender of the bearing that Internal and external cycle can not throw off.
For solving the problems of the technologies described above; The present invention adopts following technical scheme: the said suspender that is used to lift the bearing that Internal and external cycle can not throw off comprises two semicircle clips that are used for clamping bearing; The radius of said two semicircle clips is less than the radius of outside race; The one of which end is hinged through bearing pin, and the other end passes through bolted connection; Two semicircle clip butt joints are circular, evenly are provided with three suspension centres on its external peripheral surface.
The inner circumferential surface of said semicircle clip promptly with the outside race contact surface, is inlaid with annular copper coin, and the protection bearing is avoided damage.Evenly be provided with the bulb ringbolt that can sink in the bearing oil groove on the said semicircle clip, be used for the lifting protection.
The present invention can be used for lifting the bearing that Internal and external cycle can not be thrown off; Mainly contain three major types such as tilting bearing, deep groove ball bearing, angular contact ball bearing, the no suspension centre problem of the lifting of solution level effectively dwindles the method for two semicircle clip internal diameters to hold outside race tightly through binding bolt; Make suspender encircle outside race and the enough big diametral load of generation; Make circular clip of two halves and outside race produce static friction force, overcome the safety lifting that bearing gravity is realized bearing, realized the lifting of bearing level.The present invention adopts that the bulb ringbolt is fastening to carry out secondary protection to suspender, has realized the bearing lifting safely and reliably.Adopt two semicircle clips, realized the quick and convenient clamping of suspender, reduced labour intensity, through encircling the direct hanging bearing of the friction force outer ring that outside race produces, thereby avoided the interference of suspender the bearing inner ring assembling.
Description of drawings
Fig. 1 is integral structure figure of the present invention;
Fig. 2 is the postrotational local structure view of the local amplification in A place among Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2; The said suspender that is used to lift the bearing that Internal and external cycle can not throw off comprises two semicircle clips 2 that are used for clamping bearing; The radius of said two semicircle clips 2 is less than the radius of outside race, and the one of which end is hinged through bearing pin 4, and the other end connects through bolt 3; Two semicircle clip 2 butt joints are circular, evenly are provided with three suspension centres 1 on its external peripheral surface.
The inner circumferential surface of said semicircle clip 2 promptly with the outside race contact surface, is inlaid with annular copper coin 6, and the protection bearing is avoided damage.Six bulb ringbolts 5 that can sink in the bearing oil groove evenly are set on the said semicircle clip 2, are used for the lifting protection.
Adopt two radiuses to encircle outside race, make clip hold outside race tightly, outside race is produced radial pressure through bolted less than the band breach suspender of semicircle clip 2 formation of outside race.During lifting, the static friction force equalizer bearing weight that relies on two semicircle clips 2 and outside race to produce.
Except that relying on friction force equalizer bearing weight, also adopt bulb ringbolt 5, before the lifting, be screwed in the lubrication groove.Through the screw clip that swells, prevent that the bearing clip from getting loose, play secondary safety precaution effect.Adopt the bulb formula can avoid damaging outside race.
Adopting two semicircle clips 2, is S. A. with bearing pin 4, is convenient to the latch closure bearing during installation.Adopt bolt 3 fastening, can control Tightening moment effectively through screw-down torque during use, guarantee that clip has enough radial pressures, guarantee that clamping puts in place.Inlay annular copper coin 6 in two semicircle clips 2, effectively the prevention shaft bearing outer-ring prevents that suspender from colliding with, scratching bearing.
The present invention can be used for lifting the bearing that Internal and external cycle can not be thrown off; Mainly contain three major types such as tilting bearing, deep groove ball bearing, angular contact ball bearing, the no suspension centre problem of the lifting of solution level effectively dwindles the method for two semicircle clip 2 internal diameters to hold outside race tightly through binding bolt 3; Make suspender encircle outside race and the enough big diametral load of generation; Make two semicircle clips 2 produce static friction force, overcome the safety lifting that bearing gravity is realized bearing, realize the lifting of bearing level with outside race.Adopt that bulb ringbolt 5 is fastening to carry out the secondary protection to suspender; Realize the bearing lifting safely and reliably; Adopt the circular clip 2 of two halves, realize the quick and convenient clamping of suspender, reduced labour intensity; Through encircling the direct hanging bearing of the friction force outer ring that outside race produces, avoided the interference of suspender to the bearing inner ring assembling.
