Abstract

The utility model discloses a novel rear bearing device, which comprises a compressor main body and a rear bearing. The rear bearing is arranged at the position of a rear end inside the compressor main body; an annular oil groove is arranged in the rear bearing; the annular oil groove is connected with an oil guide groove arranged in the rear bearing; the oil guide groove is at an angle of 35 degrees with a horizontal air inlet arranged in the compressor main body; and meanwhile, the oil guide groove is connected with an oil sump arranged inside the compressor main body. The novel rear bearing device has the beneficial effects that the structure is simple and the production cost is low; through arranging the structure of the oil guide groove, lubrication oil plays a role in lubricating the whole compressor; the novel rear bearing device is more energy-saving and environment-friendly; and the service life of a component inside the compressor is effectively prolonged, and the work efficiency of each component is effectively improved.

Description

A kind of novel rear bearing device

Technical field

The utility model relates to a kind of rear bearing device, particularly a kind of rear bearing device.

Background technique

Existing compressor is because suction port becomes 90 ° with the relief opening position, after the position that causes installing the extension angle changes; The rear bearing filler opening is not in oil sump, and refrigeration oil can not enter compressor from oilhole, can not be lubricated rotor and the front and back bearings of compressor, causes bearing life greatly to reduce.

Summary of the invention

For the structural disadvantages of the rear bearing that has compressor now, the utility model provides a kind of novel rear bearing device.

To achieve these goals, the utility model institute Adopts measure

A kind of novel rear bearing device comprises compressor main body, rear bearing, and the inner back-end location of described compressor main body is provided with rear bearing, is provided with annular oil groove on the rear bearing; The oil guide slot that arranges on annular oil groove and the rear bearing is connected;

The horizontal suction port that arranges on described oil guide slot and the compressor main body becomes 35 °, and simultaneously, oil guide slot links to each other with the inner oil sump that arranges of compressor main body.

The beneficial effects of the utility model: simple in structure, cost of production is low; By the oil guide slot structure is set so that lubricant oil to whole compressor lubricate, more energy-conserving and environment-protective, the working life of Effective Raise compressor inner member and the working efficiency of each parts.

Embodiment

A kind of novel rear bearing device such as Fig. 1, Fig. 2, shown in Figure 4, comprises compressor main body 1, rear bearing 2, and described compressor main body 1 inner back-end location is provided with rear bearing 2, is provided with annular oil groove 3 on the rear bearing 2, as shown in Figure 3; The oil guide slot 4 that arranges on annular oil groove 3 and the rear bearing 2 is connected.In the actual implementation process of patent, as shown in Figure 2,5 one-tenths 35 ° of the horizontal suction ports that arranges on oil guide slot 4 and the compressor main body 1, simultaneously, oil guide slot 4 links to each other with the oil sump 7 of compressor main body 1 inner setting, as shown in Figure 3.When patent work, as shown in Figure 1, after becoming 90 ° of positions that install to hang angles to change with relief opening 6 positions by the suction port 5 because of compressor, as shown in Figure 2, by improving structure so that the filler opening of oil guide slot 4 in oil sump, lubricant oil imports annular oil grooves 3 and then enters compressor from oil guide slot 4 smoothly, and rotor and the front and back bearings of compressor is lubricated; By the oil guide slot structure is set so that lubricant oil to whole compressor lubricate, more energy-conserving and environment-protective, the working life of Effective Raise compressor inner member and the working efficiency of each parts.

Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
