Abstract

The utility model discloses a special bearing for an automobile generator. On the basis of the standard value of the national standard GB276-64, the external diameter and the internal diameter of the bearing are not changed, the width of one side of the outer shaft washer of the bearing is increased one third; dust-proof baffles (2) are connected with the two sides of the bearing, the space between dust-proof baffles (2) on the two sides is filled with a high-temperature-resistant abrasion-resistant molybdenum disulfide grease and sealed, multiple-position symmetric clamping grooves are processed in the external diameter of the bearing outer shaft washer (3) in the axial direction to increase radical friction force, so as to prevent the bearing outer shaft washer from being displaced; multiple-position clamping grooves are processed in the internal diameter of a bearing inner shaft washer (1) in the axial direction to prevent the damage to the generator caused by shaft grinding shaft. By adopting the special bearing, the effects of dust proofing, high temperature resistance, and the abrasion resistance are achieved, the service life of the bearing is prolonged, and the service life of the generator is prolonged greatly.

Description

Automobile current generator special bearing

Affiliated technical field

The utility model relates to auto parts machinery bearing, especially for automobile generating special bearing.

Background technique

Automobile is one of modern means of communication, and large, medium and small automobile is all provided with generator, drives generator to work by motor car engine.Because temperature is high, dust is large, add the vibrations of jolting of up train, make dynamo bearing rapid wear perishable, often cause bearing Yin Gaowen oil starvation, intensification to force the outer blowout patche displacement of bearing, the seat that runs out bearing, cause generator to scrap.There is 50 percent automobile current generator therefore to scrap according to investigation.

Summary of the invention

The object of the utility model automobile current generator special bearing is to provide a kind of high temperature resistant, wear-resistant, dustproof bearing and more firm automobile current generator special bearing of bearing support of making again.

For reaching above-mentioned purpose, automobile current generator special bearing of the present utility model is achieved in that on the basis of standard GB/T 276-64 bearing standard, outer blowout patche one side is widened to 1/3rd, in order to increase steadiness, the cylindrical of blowout patche, interior blowout patche inner circle are axially processed symmetrical draw-in groove outside, its width is 4 millimeters, and the degree of depth is 0.3 millimeter, and draw-in groove multidigit increases Radial resistant force and prevents the loosening of the outer blowout patche of bearing and bearing support.Install dustproof plate washer additional in bearing both sides, available metal sheet, also can make by high strength plastics.In bearing, add high temperature resistant, anti abrasive molybdenum disulfide butter.

Below in conjunction with accompanying drawing and specific embodiments, the utility model is described in further details.

Brief description of the drawings

Fig. 1 is the front schematic view of the utility model automobile current generator special bearing.

Fig. 2 is the side generalized section of this utility car generator special bearing.

In figure: 1, interior blowout patche; 2, plate washer; 3, outer blowout patche; 4, bearing; 5, shelves groove.

Specific embodiments:

The special bearing of automobile current generator shown in Fig. 1, under the constant prerequisite of national GB276-64 standard rolling bearing wind external diameter, width widen 1/3rd is increased to stability, increase the space in bearing, be convenient to add high temperature resistant, anti abrasive molybdenum disulfide, butter and seal, outside bearing, blowout patche 3 outside journal axles are to being processed with the symmetrical draw-in groove of multidigit, increase radial frictional force, prevent that outside bearing, blowout patche 3 is rinsed nation, in the interior axial processing draw-in groove multidigit of the interior blowout patche 1 of bearing 4, prevent that generator shaft from grinding axle and causing damage.The draw-in groove degree of depth is 0.3ma, and width 4mm improves working stability, in order to prevent that slip between the outer blowout patche of bearing and bearing support is except increasing several roads to draw-in groove, and adds metal-to-metal adhesive to reinforce, and makes it have more stability.

Claims

1. an automobile current generator special bearing, is characterized in that: on the basis of standard GB/T 276-64 scale value, only outer blowout patche one side is increased to 1/3rd of width.

2. automobile current generator special bearing according to claim 1, is characterized in that: the cylindrical of blowout patche outside bearing (3), interior blowout patche (1) inner circle are axially processed symmetrical draw-in groove, and its width is 4 millimeters, and the degree of depth is 0.3 millimeter.

3. automobile current generator special bearing according to claim 1, is characterized in that: bearing both sides install dust-proof guard (2) additional, the molybdenum disulfide butter of annotating high temperature resistant, wear-resisting between dust-proof guard (2).
