Abstract
The utility model discloses a precise bearing for an air conditioner. The precise bearing comprises an inner ring (1) of the bearing, a ball (2) and an outer ring (3), wherein a plurality of axial slits (12) are formed in one end of the inner ring (1); a taper thread (11) is formed on the outer wall of the inner ring (1) on which the axial slits (12) are formed; a locking sleeve (4) is in threaded connection with the taper thread (11) of the inner ring (1); a fan-shaped groove (41) penetrating through the inner and outer sidewalls of the locking sleeve (4) is formed in the locking sleeve (4); a threaded hole (42) is formed in the locking sleeve (4) on one side of the groove, and a stepped hole (43) is formed in the locking sleeve (4) on the other side of the groove (41); a fastening bolt (5) penetrates through the stepped hole (43) to be in threaded connection with the interior of the threaded hole (42). According to the precise bearing, the locking sleeve is used for locking a rotating shaft in a rotating way, and the pitch on the locking sleeve is reduced through the bolt, so that the locking sleeve is fixed on the inner ring of the bearing; due to the adoption of the locking structure, difficulty in the mounting of the bearing is lowered.
Description
Technical field:
The utility model relates to the technical field of bearing, more specifically to a kind of air-conditioning precision bearing of locking cover.
Background technique:
At present, air-conditioning is broadly divided into domestic air conditioning, business air conditioner, car air conditioner, central air-conditioner.Refrigerating and air conditioning etc., no matter any air-conditioning, its core component is all compressors, when compressor operating, can make a noise, be important measures that reduce noise and select the bearing of highi degree of accuracy, low noise.And on more existing air-conditioning precision bearings, generally can use lock sleeve to increase the radial pressure of bearing inner race to rotating shaft in compressor, thus increase frictional force, thus make bearing inner race be fastened on stability, the reduction noise of increase rotating shaft operation in rotating shaft.And more existing bearings when mounted, its lock sleeve without effective locating point, is easily moving axially and radial rotating its lock sleeve tighting a bolt on bearing inner race, and it has increased the degree of difficulty of installing.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of air-conditioning precision bearing is provided, and it has adopted a kind of lock sleeve of new locking mode, uses this lock sleeve locking convenient, has reduced the degree of difficulty of settling.
Technology solution of the present utility model is as follows:
Air-conditioning precision bearing, comprises inner ring, ball and the outer ring of bearing, and one end of inner ring forms some axial slits, on the interior ring outer wall at axial slits place, forms tapered thread, on the tapered thread of inner ring 1, is bolted with lock sleeve; On described lock sleeve, form the fan-shaped groove that runs through outer side wall in lock sleeve, on the lock sleeve of groove one side, form tapped hole, on the lock sleeve of the opposite side of groove, form step hole, clamping bolt is screwed onto in tapped hole through step hole.
The minimum diameter of described lock sleeve madial wall is greater than the diameter of the madial wall of inner ring.
The length of the inner ring of described bearing is greater than the length of outer ring, and the axial slits on inner ring is positioned at the outside of outer ring.
One side of the described lock sleeve that forms tapped hole is the side near the outer ring of bearing, and the clamping bolt being screwed onto on tapped hole adopts hexagon socket head cap screw.
On outer side wall on described lock sleeve, form some shrinkage pools, shrinkage pool is evenly distributed on the outer side wall of lock sleeve.
The beneficial effects of the utility model are:
Thereby it utilizes the rotating shaft of lock sleeve rotational lock and makes the pitch on its lock sleeve reduce to be fixed on the inner ring of bearing by bolt, thereby has adopted this kind of Novel locking structure to fall bearings mounted degree of difficulty.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of middle lock sleeve of the present utility model.
In figure: 1, inner ring; 2, ball; 3, outer ring; 4, lock sleeve; 5, clamping bolt; 11, tapered thread; 12, axial slits; 41, groove; 42, tapped hole; 43, step hole; 44, shrinkage pool.
Embodiment:
Embodiment: see shown in Fig. 1,2, air-conditioning precision bearing, comprises inner ring 1, ball 2 and the outer ring 3 of bearing, and one end of inner ring 1 forms some axial slits 12, on inner ring 1 outer wall at axial slits 12 places, form tapered thread 11, on the tapered thread 11 of inner ring 1, be bolted with lock sleeve 4; On described lock sleeve 4, form the fan-shaped groove 41 that runs through lock sleeve 4 interior outer side walls, on the lock sleeve 4 of groove 41 1 sides, form tapped hole 42, on the lock sleeve 4 of the opposite side of groove 41, form step hole 43, clamping bolt 5 is screwed onto in tapped hole 42 through step hole 43.
The minimum diameter of described lock sleeve 4 madial walls is greater than the diameter of the madial wall of inner ring 1.
The length of the inner ring 1 of described bearing is greater than the length of outer ring 3, and the axial slits 12 on inner ring 1 is positioned at the outside of outer ring 3.
One side of the described lock sleeve 4 that forms tapped hole 42 is that the clamping bolt 5 being screwed onto on tapped hole 42 adopts hexagon socket head cap screw near a side of the outer ring 3 of bearing.
On outer side wall on described lock sleeve 4, form some shrinkage pools 44, shrinkage pool 44 is evenly distributed on the outer side wall of lock sleeve 4.
Working principle: the lock sleeve of original bearing is to form a gap slot on lock sleeve, the lock sleeve at gap slot place is provided with bolt, thereby the diameter that reduces lock sleeve inner side by tighting a bolt plays locking effect, but its lock sleeve axially and radially do not carry out spacing, in bolt process, can there is radial rotating and move axially, increase the degree of difficulty of installing.And inner lock sleeve 4 that becomes to have tapered thread of employing of the present utility model, be fixed on by knuckle buster on the shrinkage pool of lock sleeve 4 and be rotated and tighten, thereby the outside diameter that reduces gradually the inner ring 1 of the bearing at the place of being spirally connected is fastened on bearing in rotating shaft, lock sleeve 4 rotation tighten after at the clamping bolt 5 of tightening on it, thereby make it make the pitch on its lock sleeve 4 reduce to be fixed on the inner ring 1 of bearing, brought facility for bearing is installed.
