Abstract
The utility model discloses a front cover bearing supporting device for a gear oil pump. The front cover bearing supporting device comprises a spindle and a gear bank which are arranged in a shell. Front and rear covers are respectively arranged at both ends of the shell; both the front and rear covers are sleeved on the spindle and are fixedly arranged on the shell; a cavity is arranged in the front cover; a bearing, a shaft elastic check ring, a sealing ring, a check ring and a sealing cover are sequentially arranged in the cavity from inside to outside; the spindle passes through the bearing, the shaft elastic check ring, the sealing ring, the check ring and the sealing cover and is in running fit with the bearing; the spindle extends out of the sealing cover; the sealing cover is in seal connection with the front cover; a ring-shaped groove is arranged in the cavity wall of the cavity in the front cover; and the check ring is clamped in the ring-shaped groove. The front cover bearing supporting device for the gear oil pump has a simple structure, is convenient to manufacture and use, has an obvious improvement effect on improving the radial force and damage which are generated by a belt to the spindle and can ensure the service life of the gear oil pump to be prolonged.
Description
Technical field
The utility model relates to the gear oil pump field, and concrete is a kind of gear oil pump Front Cover Bearing support device.
Background technique
Gear oil pump is applicable to and carries the various liquid that lubricity is arranged that temperature is not higher than 70 ℃, like 200 ℃ of need high temperature, but the adapted exotic material get final product, viscosity is 5 * 10-5～1.5 * 10-3m2/S.This pump be not suitable for carry corrosive, contain hard particles or fiber, highly volatilization or the low liquid of flash-point, like gasoline, benzene etc., in long-term using process,, cause the too early damage of oil pump easily because belt transmission makes the main shaft generation rock easily.
The model utility content
It is a kind of simple in structure that the utility model provides, and manufacturing process is simple, can reduce belt and rock the gear oil pump Front Cover Bearing bearing device of the power of generation to the damage of pump.
The technological scheme of the utility model:
Gear oil pump Front Cover Bearing support device; Comprise the main shaft and the gear train that are installed in the housing, the two ends of housing are separately installed with forward and backward lid, and described forward and backward lid all is enclosed within on the described main shaft and is fixedly installed on the described housing; It is characterized in that: have cavity in the described protecgulum; From the lining bearing, circlip for shaft, seal ring, back-up ring and sealing cover outwards are installed successively in the cavity, described main shaft passes these parts, and is rotatably assorted with described bearing; Described main shaft stretches out described sealing cover, is tightly connected between sealing cover and the front cover.
Described gear oil pump Front Cover Bearing support device is characterized in that: have circular groove on the cavity wall in the described front cover, described back-up ring is connected in the described circular groove.
The advantage of the utility model:
The utility model is simple in structure, makes easy to usely, for improving the radial force that belt produces main shaft and producing to damage tangible improvement is arranged, and can increase the working life of gear oil pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, gear oil pump Front Cover Bearing support device comprises the main shaft 2 and the gear train that are installed in the housing 1; The two ends of housing 1 are separately installed with forward and backward lid 3,4; Described forward and backward lid 3,4 all is enclosed within on the described main shaft 2 and is fixedly installed on the described housing 1, has cavity in the protecgulum 3, interior bearing 5, circlip for shaft 6, seal ring 7, back-up ring 8 and the sealing cover 9 of outwards being equipped with successively from the lining of cavity; Described main shaft 2 passes these parts; And be rotatably assorted with described bearing 5, described main shaft 2 stretches out described sealing cover 9, is tightly connected between sealing cover 9 and the front cover 3; Have circular groove on the cavity wall in the front cover 3, described back-up ring 8 is connected in the described circular groove.
