Abstract
The utility model relates to a deep groove ball bearing with an expansion compensation ring, which comprises an outer shell, a bearing outer ring, a bearing inner ring, a rolling body and a retaining machine, wherein the inner side of the bearing outer ring is provided with single-row parallel single-groove rolling passages. The contact surface of the cross sections of the rolling passages is provided with a circular arc surface matched with the rolling body. An inner ring is arranged in the rolling body, and is provided with an inner channel corresponding to the rolling body, and the periphery of the inner ring is provided with a block edge corresponding to the rolling body. The outer diameter of the bearing is tightly matched with the inner diameter of a cast aluminium outer shell seat, and an inner hole of the bearing is in a small clearance fit with a steel eccentric shaft. Even in high operating temperature, the outer diameter of the bearing outer ring is fixedly matched with the inner diameter of the cast aluminium outer shell seat. The utility model has the advantages of compact structure, small size, light weight, easy installation, high temperature resistance and long service life, and is widely applied to a swirl type air conditioning compressor of an automobile.
Description
[technical field]
The utility model relates to a kind of deep groove ball bearing, especially relates to a kind of deep groove ball bearing that is applied to the architecture advances of band expansion compensation ring on the vortex type automobile air conditioner compressor.
[background technique]
At present, known automobile air conditioner compressor bearing shortcoming is: first, traditional bearing products does not structurally have the plastic expansion endless belt, under cast aluminium shell, bearing outer ring thermal expansion simultaneously, can't guarantee the secure fit of bearing outer ring external diameter and cast aluminium outer shell base internal diameter, cause bearing loosening and produce different sound; The second, when assembling, need adjust play, pretension, interpolation lubricating grease with motorcar air conditioner, the workmanship situation of its bearing is controlled by many personal factors in the assembly process, and assembling difficulty is big, assembling line length, cost height, and poor reliability.
[model utility content]
For overcome existing automobile air conditioner compressor bearing exist bearing loosening and produce different sound, assembling difficulty is big, the assembling line length, the shortcoming of cost height and poor reliability, the utility model provide a kind of deep groove ball bearing that is applied to vortex type automobile air conditioner compressor band expansion compensation ring.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of deep groove ball bearing with the expansion compensation ring, comprise shell, bearing inner race, bearing outer ring, rolling element and retainer, the inboard of described bearing outer ring is provided with single-row parallel single ditch raceway, the surface of contact in its cross section is the arc surface that rolling element matches, inside at rolling element is provided with inner ring, and this inner ring is provided with the interior raceway groove and the periphery that adapt with rolling element and is provided with the shelves limit that adapts with rolling element.
Described bearing outside diameter and outer shell base internal diameter drive fit, little Spielpassung between brearing bore and the steel eccentric shaft.
The outer surface of described bearing is provided with two circumferential rectangle grooves, in the circumferential rectangle groove with plastics injection bearing outer surface, is processed to form two plastics endless belt that protrude from bearing outside diameter a little by follow-up precision.
The beneficial effects of the utility model are: the utility model bearing outside diameter and cast aluminium outer shell base internal diameter drive fit, brearing bore and the little Spielpassung of steel eccentric shaft, during the utility model work, because ambient temperature is higher, make the thermal expansion simultaneously of cast aluminium shell, bearing outer ring, plastics endless belt, but the thermal expansion of plastics endless belt changes much larger than the thermal expansion of cast aluminium shell and changes; Like this, even under very high operating temperature, also can guarantee the secure fit of bearing outer ring external diameter and cast aluminium outer shell base internal diameter.The utlity model has compact structure, small-sized, light weight, easily install, high temperature resistant, advantage that the life-span is long.Be widely used on the vortex type automobile air conditioner compressor.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model plan view;
Fig. 2 is an A partial sectional view among Fig. 1.
Among the figure: 1-cast aluminium shell, 2-plastics endless belt, 3-outer ring, 4-rolling element, 5-retainer, 6-inner ring, 7, two circumferential rectangle grooves of 8-bearing outer ring appearance, the single ditch raceway in 9-outer ring, 10-bear inner ring grooved railway, grade limit that 11-septal fossula periphery and rolling element adapt.
[embodiment]
Referring to Fig. 1 and Fig. 2, what Fig. 1 was represented is the sectional view of the utility model agent structure, the deep groove ball bearing of vortex type automobile air conditioner compressor band expansion compensation ring is to form with the composite structure of the deep groove ball bearing of the single-row band expansion compensation ring of two covers, and this bearing structure is the new product of developing according to the vortex type automobile air conditioner compressor needs.
A kind of deep groove ball bearing with the expansion compensation ring, described bearing adopts special single-row ball-bearing structure, the design of bearing outer ring 3 external diameters has the temperature compensation structure, design two circumferential rectangle grooves 7,8 at bearing outside surface, a kind of special plastics are injected this rectangle groove 7,8, and be processed to form two plastics endless belt 2 that protrude from bearing outside diameter a little by follow-up precision.The external diameter surface design of the internal diameter of bearing outer ring 3 and bearing inner race 6 has single-row parallel single ditch raceway 9, design has rolling element 4 between single ditch raceway 9 in outer ring and the inner ring list ditch raceway 10, this rolling element 4 is a steel ball, and design has retainer 5 between outer ring raceway 9 and the bear inner ring grooved railway 10.
The plastics endless belt 2 of described bearing outside diameter, this special plastics have the thermal linear expansion coefficient of 4 to 5 times of suitable cast aluminiums, make cast aluminium shell 1, bearing outer ring 3, plastic hoop 2 be with thermal expansions simultaneously, but 2 thermal expansions of plastics endless belt change the thermal expansion variation much larger than cast aluminium shell 1.Like this, even under very high operating temperature, also can guarantee the secure fit of bearing outer ring 3 external diameters and 1 internal diameter of cast aluminium shell.
The inboard of described bearing outer ring 3 is provided with single-row parallel single ditch raceway 9, the surface of contact in its cross section is the arc surface that rolling element 4 matches, below rolling element 4, be provided with inner ring 6, and be provided with the interior raceway groove 10 that adapts with rolling element 4 and periphery is provided with the shelves limit 11 that adapts with rolling element 4.On bearing inner race 6, be provided with a single-row parallel single ditch raceway 10, place therebetween rolling element 4 with 9 clampings of bearing outer ring list ditch raceway.Be provided with retainer 5 between bear inner ring grooved railway 10 and the outer ring raceway 9, evenly isolate each rolling element 4, and guide each rolling element 4 proper motion.
The utility model bearing outside diameter and cast aluminium shell 1 internal diameter tight fit, brearing bore and steel eccentric shaft Little matched in clearance even under very high operating temperature, also can guarantee bearing outer ring 3 external diameters and cast aluminium shell 1 The secure fit of seat internal diameter. The utlity model has compact conformation, small-sized, light weight, easily install, high temperature resistant, The advantage that life-span is long. Be widely used on the vortex type automobile air conditioner compressor.
