Abstract
The utility model discloses a noise reduction structure of a gear meshed oil blocking area. The noise reduction structure comprises a gear assembly plate, wherein a group of assembly holes are formed in the assembly plate; '8'-shaped arc grooves are formed in the middles of two sides of the assembly plate; cubic grooves are formed in the bottoms of the arc grooves of the assembly plate; and guide slots are formed in two sides of the bottom of each cubic groove. The noise reduction structure is simple and convenient to manufacture; and furthermore, the output efficiency of an oil pump can be effectively improved, blocking is reduced, and the noise of the oil pump can be reduced and even eliminated.
Description
Technical field
The utility model relates to the gear oil pump field, and concrete is a kind of gear engagement pocketed oil district noise reducing structure.
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 volatilize or the low liquid of flash-point, like gasoline, benzene etc., transmit energy between the gear through being meshing with each other; The gear oil pump meshed gears is in long-term operation process; Many problems may appear, for example, and easy blocking, generation noise etc.; Can have influence on the delivery efficiency of oil pump, reduce the working life of oil pump.
The model utility content
It is a kind of simple in structure, easily manufactured that the utility model provides, and can effectively improve the delivery efficiency of oil pump, reduces the gear engagement pocketed oil district noise reducing structure that stops up.
The technological scheme of the utility model:
Gear engagement pocketed oil district noise reducing structure; Comprise the gear mounting plate; Described mounting plate has one group of mounting hole; It is characterized in that: two middle side parts of described mounting plate have the cabochon groove, are " 8 " font that the cabochon bottom portion of groove of described mounting plate all has the cube groove, and described cube bottom portion of groove both sides all have guide groove.
Described gear engagement pocketed oil district noise reducing structure, it is characterized in that: described cabochon groove, guide groove are positioned at the gear meshing place.
The advantage of the utility model:
The utility model is simple in structure, and is easily manufactured, can effectively improve the delivery efficiency of oil pump, reduces and stops up, and reduces even eliminate the noise of oil pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
