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 for lifting the suspender of the bearing that Internal and external cycle can not throw off.
Background technology
When the bearing assembles such as general medium-and-large-sized self-aligning roller bearing, deep groove ball bearing, angular contact ball bearing or transhipment, need level lifting to place, along bearing axle to lifting, but because bearing enclose end face should not arrange hole for hoist position, therefore, cause lifting difficulty, and have potential safety hazard.
Existing bearing hoister adopts flexible suspender belt to be banded on bearing enclose for realizing level lifting conventionally, and its shortcoming is exactly, and needs to be wound around suspender belt on bearing inner ring, and in the time requiring the assembling of bearing inner ring and axle journal fit system, this suspender cannot use.Therefore, need a kind of new suspender, solve the difficulty of existing lifting, thereby avoided the interference of suspender to bearing inner ring assembling.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of not only facilitated bearing safty hoisting but also ensure bearing injury-free for lifting 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: describedly comprise two semicircle clips for clamping bearing for the suspender that lifts the bearing that Internal and external cycle can not throw off, the radius of described two semicircle clips is less than the radius of outside race, its one end is hinged by bearing pin, and the other end is bolted; Two semicircle clip docking are circular, are evenly provided with three suspension centres on its external peripheral surface.
The inner circumferential surface of described semicircle clip,, with outside race contact surface, is inlaid with annular copper coin, and protection bearing is avoided damage.On described semicircle clip, be evenly provided with the bulb ringbolt that can sink in bearing oil groove, for lifting protection.
The present invention can be used for lifting the bearing that Internal and external cycle can not be thrown off, mainly contain the three major types such as tilting bearing, deep groove ball bearing, angular contact ball bearing, solution level effectively lifts without suspension centre problem, dwindle the method for two semicircle clip internal diameters by binding bolt and hold outside race tightly, make suspender encircle outside race and produce enough large diametral load, make the circular clip of two halves and outside race produce static friction force, overcome bearing gravity and realize lifting by crane safely of bearing, realized the lifting of bearing level.The present invention adopts that bulb ringbolt is fastening carries out secondary protection to suspender, has realized safely and reliably bearing lifting.Adopt two semicircle clips, realized the quick and convenient clamping of suspender, reduced labour intensity, the direct hanging bearing of the friction force outer ring producing by encircling outside race, thus avoid the interference of suspender to bearing inner ring assembling.
Brief description of the 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 in Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, describedly comprise two semicircle clips 2 for clamping bearing for the suspender that lifts the bearing that Internal and external cycle can not throw off, the radius of described two semicircle clips 2 is less than the radius of outside race, and its one end is hinged by bearing pin 4, and the other end connects by bolt 3; It is circular that two semicircle clips 2 dock, and is evenly provided with three suspension centres 1 on its external peripheral surface.
The inner circumferential surface of described semicircle clip 2, with outside race contact surface, is inlaid with annular copper coin 6, and protection bearing is avoided damage.Six bulb ringbolts 5 that can sink in bearing oil groove are evenly set, for lifting protection on described semicircle clip 2.
The band breach suspender that the semicircle clip 2 that adopts two radiuses to be less than outside race forms is encircled outside race, makes clip hold outside race tightly by bolted, and outside race is produced to radial pressure.When lifting, the static friction force equalizer bearing weight that relies on two semicircle clips 2 and outside race to produce.
Except relying on friction force equalizer bearing weight, also adopt bulb ringbolt 5, before lifting, be screwed in lubrication groove.By the screw clip that swells, prevent that bearing clip from getting loose, and plays secondary safety protection effect.Adopt bulb type can avoid damaging outside race.
Adopt two semicircle clips 2, taking bearing pin 4 as S. A., when installation, be convenient to latch closure bearing.Adopt bolt 3 fastening, when use, can effectively control Tightening moment by screw-down torque, ensure that clip has enough radial pressures, guarantee that clamping puts in place.In two semicircle clips 2, inlay annular copper coin 6, effectively 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 the three major types such as tilting bearing, deep groove ball bearing, angular contact ball bearing, solution level effectively lifts without suspension centre problem, dwindle the method for two semicircle clip 2 internal diameters by binding bolt 3 and hold outside race tightly, make suspender encircle outside race and produce enough large diametral load, make two semicircle clips 2 produce static friction force with outside race, overcome bearing gravity and realize lifting by crane safely of bearing, realize the lifting of bearing level.Employing bulb ringbolt 5 is fastening carries out secondary protection to suspender, realize safely and reliably bearing lifting, adopt the circular clip 2 of two halves, realize the quick and convenient clamping of suspender, reduce labour intensity, the direct hanging bearing of the friction force outer ring producing by encircling outside race, has avoided the interference of suspender to bearing inner ring assembling.
