Abstract
The utility model discloses an oil pump drive gear. The oil pump drive gear comprises a gear disc which is subjected to surface non-defective treatment and rust-proof treatment, a plurality of gear teeth are arranged at the peripheral edge of the gear disc, a tooth space is reserved between each two adjacent gear teeth, and arc-shaped chamfers are arranged on two sides of the bottom of each tooth space. A through hole is reserved in the middle of the gear disc, a rectangular key groove is arranged on one side of the through hole, and sealing strips are arranged at two ends of the rectangular key groove along the inner wall of the rectangular key groove. The oil pump drive gear is compact in structure, high in precision, small in vibration and stable in rotating speed, and by the aid of the arc-shaped chamfers arranged in the tooth spaces, meshing tightness among gears is enhanced, wear among the gears is reduced, transmission efficiency is improved, and noise is lowered. In addition, since the rectangular key groove which is provided with the sealing strips is arranged on the gear, assembly and maintenance of the gear and the drive shaft are facilitated, good sealability is guaranteed, and further normal operation of an oil pump is guaranteed.
Description
Technical field
The utility model relates to the part field of oil pump, specifically a kind of Oil pump drive gear.
Background technique
In lubrication system, oil pump is to force machine oil to deliver to the device of engine movement part from oil sump.Gear is the inner common gearing parts of oil pump.The gear of existing air compressor mounted inside vibrates larger in the course of the work, produces a large amount of noises when causing work, for a long time can be so that the wearing and tearing between the gear be larger, and transmission occurs loosening, thereby has influence on the normal operation of oil pump.
The model utility content
The purpose of this utility model provides a kind of Oil pump drive gear, and arc angling is set in teeth groove, strengthens the tightness that meshes between the gear, reduces the wearing and tearing between the gear, to improve the transmission effect, reduces noise; In addition, at gear the rectangle keyway is set, to make things convenient for the I﹠ M of gear and live axle.
The technical solution of the utility model is as follows:
A kind of Oil pump drive gear, include by surperficial zero defect and carry out antirust processing wheel disc, edge, surrounding around wheel disc has a plurality of gear teeth respectively, and it is characterized in that: have teeth groove between adjacent two gear teeth, the both sides of described teeth groove bottom land are respectively equipped with arc angling; The middle part of described wheel disc is provided with through hole, and a side of described through hole is provided with the rectangle keyway, at the two ends of described rectangle keyway, is respectively equipped with Stamping Steel Ribbon along the inwall of rectangle keyway.
Described Oil pump drive gear is characterized in that: have rotating shaft from through hole, pass and with the through hole interference fit.
The beneficial effects of the utility model:
The utility model compact structure, precision is high, and arc angling is set in teeth groove, has strengthened the tightness that meshes between the gear, has reduced the wearing and tearing between the gear, vibrates littlely, and rotating speed is steady, has improved the transmission effect, has reduced noise; In addition, the rectangle keyway is set and loads onto Stamping Steel Ribbon at gear, for the I﹠ M of gear and live axle provides convenient, also guaranteed good sealing, thereby guaranteed the normal operation of oil pump.
