Abstract
The utility model relates to a motor bearing mechanism special for a compressor, which aims to adapt to the connection of a helical gear compressor. The motor bearing mechanism comprises a rotor, a bearing outer cover, an end cover, a retainer ring for a shaft, an oil thrower, a cylindrical roller bearing and a bearing inner cover, wherein the cylindrical roller bearing is sleeved on a bearing retainer of the rotor, and the outer ring of the cylindrical roller bearing is connected with the end cover. The oil thrower and the retainer ring for the shaft are sleeved on the rotor; the right end of the oil thrower leans against the cylindrical roller bearing, and the left end of the oil thrower leans against the retainer ring for the shaft. The motor bearing mechanism has the benefits that the structure is simple, compact and reasonable; the rated dynamic load of the motor bearing mechanism is more than two times of that of the existing deep groove ball bearing with the same specification and size; meanwhile, the service life of the cylindrical roller bearing is also longer than that of the deep groove ball bearing; and the motor bearing mechanism can normally work under the action of larger radial action.
Description
Technical field
The utility model relates to a kind of compressor motor special Bearning mechanism, specifically is to adapt to helical gear compressor to connect.
Background technology
In existing threephase asynchronous Bearning mechanism, the drive end axle bearing assembly of existing Y-series, Y2 series three-phase asynchronous motor mainly is comprised of rotor, bearing end cover, internal bearing cover, end cap and deep groove ball bearing.Wherein this bearing demand in useful life was reached more than 10000 hours.Under usual condition, this bearing is bearing axial thrust and less radial pull, calculates through bearing life, and deep groove ball bearing just can satisfy user demand.In order to reduce the rotor axial play bearing is produced injury, be provided with bearing locking device at anti-drive end; Simultaneously axially applying precompression, thereby effectively reducing motor vibration and noise, to good result is arranged the useful life that prolongs bearing.Yet the bearing of supporting motor drive terminal on the compressor that helical gear connects will bear huge radial load, frictional force increases suddenly, deep groove ball bearing is owing to being spot contact bearing, easily generate heat behind the long time running and burn out, thereby can have influence on the performance of whole motor, bearing burns out simultaneously also can cause bending shaft or fracture, even can make whole burn-down of electric motor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compressor motor special Bearning mechanism is provided, and can guarantee bearing normal operation when bearing huge radial load, effective guarantee the useful life of bearing.
The technical scheme that provides according to the utility model, a kind of compressor motor special Bearning mechanism mainly comprises rotor, bearing end cover, end cap, shaft block ring, disc and internal bearing cover, the left end of described end cap is bolted bearing end cover, the right-hand member of end cap is bolted internal bearing cover, it is characterized in that: also comprise cylinder roller bearing, bearing guard at rotor is set with cylinder roller bearing, and the outer ring of cylinder roller bearing connects end cap.Suit disc and shaft block ring on the described rotor, the right-hand member of disc be near cylinder roller bearing, disc left end near shaft block ring.
Be provided with V-shaped seal ring between described bearing end cover and the rotor.
Described bearing end cover is provided with fuel filler neck.
Be provided with oilhole in the described end cap.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Its dynamic load rating will be that the twice of deep groove ball bearing dynamic load rating of former same specification size is many; Simultaneously the life-span of cylinder roller bearing is also greater than deep groove ball bearing, and bearing useful life will be more than 10 times of former deep groove ball bearing, and the part motor bearings life-span will be more than 15 times of former employing deep groove ball bearing; And can under larger radial load effect, work.

Description of reference numerals: 1-rotor, 2-V RunddichtringO, 3-bearing end cover, 4-end cap, 5-shaft block ring, 6-disc, 7-cylinder roller bearing, 8-internal bearing cover, 9-fuel filler neck, 10-oilhole.
Embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, the utility model mainly comprises rotor 1, bearing end cover 3, end cap 4, shaft block ring 5, disc 6, cylinder roller bearing 7 and internal bearing cover 8.
At the bearing guard suit cylinder roller bearing 7 of rotor 1, the outer ring of cylinder roller bearing 7 connects end cap 4.Suit disc 6 and shaft block ring 5 on the described rotor 1, the right-hand member of disc 6 be near cylinder roller bearing 7, disc 6 left end near shaft block ring 5.
The left end of described end cap 4 is bolted bearing end cover 3, and the right-hand member of end cap 4 is bolted internal bearing cover 8.Be provided with V-shaped seal ring 2 between described bearing end cover 3 and the rotor 1.
Described bearing end cover 3 is provided with fuel filler neck 9, is used for to inside interpolation lubricating grease.
Be provided with oilhole 10 in the described end cap 4, lubricating grease enters cylinder roller bearing 7 by oilhole 10
The motor drive terminal that adopts helical gear to connect in the compressor is selected cylinder roller bearing 7, the outer ring of the inside and outside lid 8 of bearing, 3 stuck cylinder roller bearings 7, the inner ring of cylinder roller bearing 7 is cancelled pretightning force (namely cancelling the wavy spring sheet) simultaneously with shaft block ring 5 axial restraints.Anti-drive end still adopts the deep groove ball bearing axial location, bearing inner race back-up ring axial restraint.Because motor drive terminal adopts cylinder roller bearing, its dynamic load rating will be that the twice of deep groove ball bearing dynamic load rating of former same specification size is many, the life formula index of cylinder roller bearing is also greater than deep groove ball bearing simultaneously, basic rating life will be more than 10 times of former deep groove ball bearing, and the part motor bearings life-span will be more than 15 times of former deep groove ball bearing.
