Abstract
The utility model belongs to an oil pump and motor part, in particular related to a shaft end sealing device of the gear oil pump and motor with middle and high speed that is essentially comprised of a front pump cover (1), a shaft (2), and an oil seal (6); wherein, the contacting place between the oil seal (6) and the shaft (2) which are arranged between the front pump cover (1) and the shaft (2) is provided with a wedge ring (3); the lip back of the wedge ring (3) and the oil seal (6) is provided with a baffle piece (4); the baffle piece (4) is fixed through the left side being blocked in a socket of the front pump cover (1) by a block spring (5). The shaft end sealing device of the gear oil pump and motor with middle and high speed is provided with a wedge ring based on the previous oil seal, which is unlikely to affect the pervious seal effect and makes the oil seal capable of bearing the impact of high pressure; besides, the oil seal is unlikely to fail due to lip turning when the oil pump and the motor are not working; therefore, the oil seal can be protected effectively and the service life of the oil pump and the motor is prolonged.
Description
Technical field
The utility model belongs to oil pump and motor part, the shaft end seal device of particularly a kind of mesohigh gear oil pump and motor.
Technical background
Lip formula outside framework oil seal is generally adopted in the sealing of hydraulic-pressure pump and motor power input and output shaft, though this sealing effect is good, but it can not bear excessive pressure, it communicates with the low-pressure cavity of pump and motor, especially pressure oil often takes place and reacts to low-pressure cavity when hydraulic system is not worked in oil hydraulic pump and motor, affacts on the oil sealing, make it turn over lip, seal failure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of oil sealing of avoiding to turn over lip, makes the mesohigh gear oil pump of its good sealing effect and the shaft end seal device of motor.
The technological scheme that the utility model technical solution problem adopts is: the shaft end seal device of mesohigh gear oil pump and motor mainly is made up of front pump cover, axle and oil sealing, be characterized in adorning a cambridge ring with the synapsis that is coupling at the front pump cover and the oil sealing between the axle of oil pump and motor, catch is equipped with at the cambridge ring and the oil seal lip back side, and the catch left side is stuck in the groove of front pump cover fixing with jump ring.
The beneficial effects of the utility model are: the shaft end seal device of mesohigh gear oil pump and motor is added with cambridge ring on former oil sealing basis; neither influence former sealing effect; make oil sealing can bear the impact of high pressure again; oil sealing can not occur turning over lip yet and makes seal failure when oil pump and motor are not worked; protect oil sealing effectively, prolong the working life of oil pump and motor.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows the shaft end seal device structural drawing of mesohigh gear oil pump and motor.
The partial enlarged drawing of Fig. 2 diagrammatic sketch 1.
Among the figure, the 1-front pump cover; The 2-axle; The 3-cambridge ring; The 4-catch; The 5-jump ring; The 6-oil sealing; 7-pressure oil;
Embodiment
Embodiment, with reference to accompanying drawing 1, the shaft end seal device of mesohigh gear oil pump and motor is the oil sealing 6 and axle 2 contacting points between front pump cover 1 and axle 2, axially adorn a cambridge ring 3 along axle 2, cambridge ring 3 can or have the nonmetal of intensity to make with metal, catch 4 is equipped with at the lip back side of cambridge ring 3 and oil sealing 6, and the left side of catch 4 is stuck in jump ring 5 in the groove of front pump cover 1 oil sealing 6 and cambridge ring 3 are fixed in the middle of front pump cover 1 and the axle 2.When pressure oil 7 reacted in the low-pressure cavity, lip can not appear turning in oil sealing.The sealing device can bear 25Mpa even the more impact of the oil pressure of high pressure.
Claims (1)
1, the shaft end seal device of a kind of mesohigh gear oil pump and motor, mainly form by front pump cover (1), axle (2) and oil sealing (6), it is characterized in that the oil sealing (6) between (2) is adorned a cambridge ring (3) with axle (a 2) contacting point at front pump cover (1) and axle, catch (4) is equipped with at the cambridge ring (3) and oil sealing (6) the lip back side, and catch (4) left side is stuck in the groove of front pump cover (1) fixing with jump ring (5).
