Description
Technical field
The utility model relates to a kind of plane thrust ball bearing that is used for totally-enclosed compressor, adopts the compressor of this bearing structure to can be applicable in the refrigeration systems such as refrigerator, refrigerator, air-conditioning.
Background technique
The structure of existing totally-enclosed compressor comprises parts such as motor 1, crankcase 2, bent axle 3, connecting rod 4, piston 5 as shown in Figure 1.During compressor operating, motor 1 drives bent axle 3 and rotates, 4 swings of bent axle 3 drivening rods, and it is reciprocating that connecting rod 4 drives piston 5, and wherein bent axle 3 is supported on the supporting surface of crankcase 2.The supporting way of bent axle 3 on crankcase 2 has multiple at present.
Fig. 1 a is depicted as the first kind supporting way of bent axle 3 on crankcase 2 of existing totally-enclosed compressor, and the lower plane 3a of bent axle 3 directly contacts with the last plane 2a of crankcase 2, is a kind of plane thrust bearing structure of slide type.The advantage of this supporting way is that the spacing L of the last plane 2a of crankcase 2 and lower plane 2b is longer, the stability of bent axle 3 when helping guaranteeing compressor operating; Frictional force when shortcoming is compressor operating between the last plane 2a of the lower plane 3a of bent axle 3 and crankcase 2 is bigger, and the efficient of compressor is lower.
Figure 2 shows that the second kind supporting way of bent axle 3 on crankcase 2 of existing totally-enclosed compressor, between the 2a of plane a plane thrust ball bearing 6 being arranged on the lower plane 3a of bent axle 3 and the crankcase 2, is a kind of plane thrust bearing structure of means of rolling.Concrete mounting type is shown in Fig. 2 a, and upper support sheet 6a, the bearing support 6b of plane thrust ball bearing 6 and the mounting hole of lower support sheet 6c are all located with bent axle 3; The lower plane 3a of upper support sheet 6a and bent axle 3 contacts, and the last plane 2a of lower support sheet 6c and crankcase 2 contacts, and the installation aperture φ a of upper support sheet 6a and the installation aperture φ c of lower support sheet 6a are measure-alike.The advantage of this supporting way is after adopting plane thrust ball bearing, can improve the efficient of compressor; Shortcoming is that the last plane 2a of crankcase 2 and the spacing L of lower plane 2b shorten the less stable of bent axle 3 during compressor operating.
Figure 3 shows that bent axle 3 the third supporting way on crankcase 2 of existing totally-enclosed compressor, between the Bearing Installation face 2c of the lower plane 3a of bent axle 3 and crankcase 2 plane thrust ball bearing 6 being arranged, is a kind of plane thrust bearing structure of improved means of rolling.Concrete mounting type is shown in Fig. 3 a, crankcase 2 has an installation projection 2d who is used for mounting plane thrust ball bearing 6, and upper support sheet 6a, the bearing support 6b of plane thrust ball bearing 6 and the mounting hole of lower support sheet 6c are all located with the installation projection 2d of crankcase 2; The lower plane 3a of upper support sheet 6a and bent axle 3 contacts, and the Bearing Installation face 2c of lower support sheet 6c and crankcase 2 contacts, and the installation aperture φ a of upper support sheet 6a and the installation aperture φ c of lower support sheet 6c are measure-alike.The advantage of this supporting way is after adopting plane thrust ball bearing, can improve the efficient of compressor; The spacing L of the last plane 2a of crankcase 2 and lower plane 2b is longer simultaneously, and the stability of bent axle 3 better during compressor operating.Shortcoming is between the lower plane 3a of the last plane 2a of crankcase 2 and bent axle 3 a less spacing h (shown in Fig. 3 a) to be arranged, more approaching with the thickness of lower support sheet 6c, at present support plate 6c is stuck between the lower plane 3a of plane 2a on the crankcase 2 and bent axle 3 easily at the assembling compressor, thereby cause the compressor cisco unity malfunction, the assembly process process of compressor is poor, and manufacturing efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of efficient that can improve compressor, can guarantee the stability of compressor operating again, can also improve the diameter-variable plane thrust ball bearing that is applied to totally-enclosed compressor of compressor Assembling Production efficient.
For solving the problems of the technologies described above, the solution that the utility model adopted is: the diameter-variable plane thrust ball bearing that is applied to totally-enclosed compressor comprises upper support sheet, bearing support and lower support sheet, the mounting hole of described lower support sheet and the mounting hole of described bearing support are located with the installation projection of compressor crankcase, the mounting hole of described upper support sheet is located with the bent axle of compressor, and the installation aperture of described upper support sheet is different with the installation aperture size of described lower support sheet.
The utility model is owing to adopted technique scheme, and it utilizes a kind of mode of structure that becomes the aperture, and make the totally-enclosed compressor of using this plane thrust ball bearing produce following remarkable result: 1, the efficient of compressor improves more than 3%; 2, utilize the installation projection of crankcase, the last plane of crankcase and the spacing of lower plane are longer, the stability of bent axle when guaranteeing compressor operating; 3, the lower support sheet of plane thrust ball bearing is directly installed between the lower plane of the last plane of crankcase and bent axle, and enough gap arranged, avoid stuck the wait abnormality of compressor, improved the manufacturing efficiency of compressor assembling because of adopting plane thrust ball bearing to cause.
