The pump is pumped in the pumping chamber, and then outputted by the driven gear and the inner 2 wheel. In order to prevent the transfer chamber _ oil outside 2, most of the escaping will be set in the cover of the cover that covers the casing - mechanical shaft seal /. , 'The conventional mechanical shaft seal includes - shaft rod holder, - spring, - swivel seat and one shaft seal = fixed seat'. The shaft rod fixing shaft is connected to the shaft hole of the casing cover, and is thinner than - bolt - The shaft end of the shaft is connected to a driven gear, and the shaft fixing seat and the rotating seat are combined, and the shaft sealing seat is attached to the casing cover, and the side of the sealed solid money is set There is a collar. Thereby, when the shaft and the driven gear rotate in synchronization, the oil in the conveying chamber can be prevented from leaking out of the casing cover. However, there is still room for improvement in the above structure: it says that the shaft seal _ touches on the cover of the casing, and the friction between the end of the slewing seat and the shaft seal seat will be Produced high and at high speeds, it is easy to produce metal. 2. When the oil is in the delivery chamber, the gap between the micro-seam _ rod and the shaft hole of the cover of the casing 5 M332133 penetrates, so that the impurities in the oil continuously accumulate around the mechanical shaft seal and Internal, and the flatness of the friction surface is destroyed, causing damage to the mechanical shaft seal. 3. When the oil penetrates into the gap between the shaft and the shaft hole of the casing cover by rolling, the rotary seat will be pushed at the same time to increase the pressure relative to the shaft seal fixing seat, thereby accelerating the speed of metal chips generation and affecting The service life of the mechanical shaft seal. In view of this, in order to improve the above-mentioned shortcomings, the internal rotation gear pump can not only effectively reduce the value and reduce the pressure, but also achieve the cleaning effect, in order to prolong the service life of the machine, and the creator has accumulated many years of experience and continuous Research and development improvements, and the creation of this creation. [New content] The main purpose of this creation is to provide a kind of feeding gear system, which can rotate the moving oil ring gear by connecting the structure between the end of the casing cover and the shaft hole with an oblique hole. At the time of the extrusion of the oil miscellaneous shell cover - Gu people, after the gap between the shaft holes between the holes to discharge 'to clean the mechanical shaft seal around the inside and inside the metal chips and impurities, and lower. Low temperature, shaft 'The service life of the Saki mechanical shaft seal. • For the purpose of the above creation, the internal transfer gear Lipu, which is provided by the creation, includes a casing-end of the casing and an inner ring gear, and the inner ring gear is coupled with a drive motor, and one machine The cover is attached to the end of the casing, and the casing cover is provided with a shaft hole for accommodating a shaft, a mechanical shaft seal and at least one bearing. The one end of the shaft is fitted with a driven tooth. Second, and from the (four) wheel train and the inner ring gears relative to each other, so that the oil from the casing - the end of the wheel: '(four) from the charm wheel lion lie when lying down, from a s output, its main technology Nothing · · The end of the mine cover - a wire hole with a M332133 oblique hole H to allow the oil to flow from the casing to the human body, and then discharged. Second, the 'scale hole system' is connected from the casing cover 1 to the circumference of the mechanical shaft seal. Bay ride, the end of the cover is provided with - the inflow slot and a discharge discharge slot respectively corresponding to the input pipe of the casing and the 9 (10) slot. ^ And the hole----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The casing 2 and a casing cover 3' are at the end of the casing 2 and the inner ring gear 22 is received in the conveying chamber 21, and the inner ring gear is called a drive two, and the casing cover 3 is After the input pipe 24, which is screwed to the 2nd end of the casing, enters, the squeeze is synchronously rotated by the unloading wheel 25 in the conveying chamber 21, and is rotated by an output pipe %. Please refer to the 3rd and 4th riding instructions. The casing cover 3 is provided with -_ Μ, _ ^ -_2, - mechanical shaft seal 33 and at least - bearing 34, the shaft hole Μ and one end of the casing 盍 3 Connected by a slanted hole 4. In implementation, the casing cover 3 includes a casing 35 and a rear cover %, and the rear cover is sealed and locked to the end of the casing 35. The shaft 35_the hole 31 is provided with a shaft 32 provided with a peak. - mechanical shaft seal and two bearings 34, the shaft fixing seat 37 is locked to the end - end of the shaft 32 and the end of the shaft fixing seat 37 is provided with an annular flange 371, and the other end is provided with a circular arrangement The protruding portion 372 is provided with a keyway 373 at the periphery of the shaft fixing seat 37, and the second limiting button 38 is placed in the key groove 373 and the other key groove 251 of the inner circumference of the driven gear 25, 7 M332133 The shaft 32 rotates in synchronization with the driven gear 25. The mechanical shaft seal 33 includes a set of springs 331 attached to the shaft 32, a swivel seat 332 that fits over the magazine 331, and a shaft seal mount 333. One end of the rotating seat 332 is provided with an annularly arranged recessed portion, and the other end is pressed against the end of the shaft seal fixing seat 333, and the shaft sealing fixing seat is fixed to the shell of the casing cover 3 by a latch 335. A ring 336 is disposed in the shaft hole 31 of the body 35, and the tearing side of the sealing seat is provided. The sleeve 336 is sleeved on the shaft to prevent leakage and the recess 334 of the rotating seat 332. The projections 372 that are relatively intimate with the shaft mount 37 are rotated in synchronization. In addition, one end of the housing 35 is provided with an inflow slot 351 and a discharge slot. When the housing 35 is locked to one end of the casing 2, the inlet and outlet slots 352 are respectively: And the output pipe %, and one end of the inclined hole $ is in communication with the discharge groove %. The other end of the inclined hole 4 is connected to the periphery of the shaft hole 31_mechanical shaft seal %. The clear tea is shown in Figures 2 and 4, 'When the oil enters the input tube 24 at the end of the casing 2, and passes through the inner ring_2 and the surface rotated from the _ wheel 25, the high moving part Γ is output tube % In addition to the output, a small part of the oil is discharged from the periphery and inside of the mechanical shaft seal 33 through the inclined hole 4 into the shaft hole, and = marriage_(4) as... Jing Jinna (4) = Therefore, this creation It has the following advantages: 1.
