Description
Technical field
The utility model relates to a kind of driving gear oil pump, is provided with the oil pump of flinger ring shape boss around particularly a kind of driving gear.
Background technique
Referring to Fig. 1; Traditional driving gear oil pump comprises the pump housing 2, pump cover 7, transmission shaft 5, driven shaft 3 and valve member; Pump cover 7 is installed on the pump housing 2 through screw 1; The two ends of transmission shaft 5 and driven shaft 3 axle respectively are located on the pump housing 2 and the pump cover 7, on this section between the pump housing 2 and the pump cover 7, adopt interference fit to be provided with active efflux tooth 6 at transmission shaft 5, and key are provided with driving gear 4 on the end outside transmission shaft 5 is positioned at pump cover 2; On this section between the pump housing 2 and the pump cover 7, adopt interference fit to be provided with slave pump tooth 14 at driven shaft 3, slave pump tooth 14 and 6 engagements of active efflux tooth; Pump cover 7 is provided with filler opening 15 and oil outlet 16; Valve member comprises that valve seat 8, hole are with snap ring 9, little " O " type circle 10, spring 11, big " O " type circle 12, spring stack 17 and steel ball 13; Valve seat 8 is installed on the pump housing 2 through big " O " type circle 12, and spring stack 17 is installed in the valve seat 8 with snap ring 9 through the hole, and spring 11 is enclosed within on the spring stack 17; One end of spring 11 withstands on steel ball 13 on the filler opening 15, and steel ball 13 is in order to cut out and to open filler opening 15.Its deficiency is: because driving gear 4 does not have annular boss on every side, when driving gear 4 rotations, do not have good oil lubrication, wearing and tearing can be more serious, and driving gear can be lacked than the gear that lubricates for 4 working lifes.
The model utility content
The utility model technical problem to be solved is to provide to the existing existing deficiency of driving gear oil pump the oil pump that is provided with flinger ring shape boss around a kind of driving gear; To improve the lubricated and wear-resisting property of driving gear; And the gear that is meshed with it also has greatly improved; Thereby the noise when having reduced the driving gear engagement, working life of having improved driving gear.
The utility model technical problem to be solved can realize through following technological scheme:
Be provided with the oil pump of flinger ring shape boss around a kind of driving gear; Comprise the pump housing, pump cover, transmission shaft, driven shaft and valve member; Pump cover is installed on the pump housing; The two ends of said transmission shaft and driven shaft axle respectively are located on the pump housing and the pump cover, are provided with the active efflux tooth in said transmission shaft employing interference fit on this section between the pump housing and the pump cover, and key is provided with driving gear on the end outside the pump cover and be positioned at said transmission shaft; On this section between the pump housing and the pump cover, adopt interference fit to be provided with the slave pump tooth at said driven shaft, slave pump tooth and the engagement of active efflux tooth; Said pump cover is provided with filler opening and oil outlet, and said valve member is installed on the said pump housing, in order to close and to open said filler opening, it is characterized in that, on the said pump housing, the outer periphery of driving gear is equipped with a flinger ring shape boss.
The utility model compared with prior art has following characteristics:
The utility model because on the pump housing, the driving gear outer periphery is equipped with a flinger ring shape boss (as long as be higher than driving gear one end just can); Can not only increase the intensity of the pump housing, also help the mobile performance of molten metal when casting, improve the percentage of A-class goods of foundry goods; The more important thing is that the lubricant oil that oozes out in the gap that can make between the transmission shaft and the pump housing drips on the driving gear; The oil that the driving gear rotation throws away the time still drips on the driving gear through flinger ring shape boss once more, fabulous improvement the lubricated and wear-resisting property of driving gear, and the gear that is meshed with it also has greatly improved; Thereby the noise when having reduced gear engagement, the working life of having improved gear.
