Technical Field

The invention belongs to the field of transmissions, and relates to six-gear transmissions.

Background

The oil and gas fracturing operation is to fracture the bottom rock to form cracks and enlarge pores under the hydraulic action of high flow and high pressure, so that the oil and gas yield is increased. In order to obtain high-pressure water power, the output power of the engine is decelerated and torque-increased through a gearbox, and a fracturing pump is driven to pump mixed water into a well.

The fracturing pump system is characterized in that a transmission used in the fracturing pump system is a heavy transmission, and comprises a fixed shaft type transmission and a planetary transmission, the transmission is mostly improved from the transmission of heavy vehicles such as engineering vehicles and the like, the requirements of fracturing operation cannot be well met, and problems occur in use.

Disclosure of Invention

The invention aims to provide six-gear transmissions, and overcomes the defects of the problems.

The technical scheme adopted by the invention is as follows:

six-gear transmission comprises an input shaft I, an intermediate shaft II, a linkage shaft III and an output shaft IV, idler gears {2, 4, 6, 7, 8, 11, 12} and fixed gears {1, 3, 5, 9, 10, 13}, clutches { C1, C2, C3, C4, C5}, wherein the input shaft I is connected with the fixed gear 1, the clutch C2 and the idler gear 2, the driving end of the clutch C2 is connected with the fixed gear 1, the driven end is connected with the idler gear 2, the intermediate shaft II is connected with the fixed gears 3, 5, the idler gears 4, 6 and the clutches C1, C5, the driving ends of the clutches C1, C5 are connected with the fixed gear 5, the driven end of the clutch C1 is connected with the idler gear 4, the driven end of the clutch C38 is connected with the idler gear 6, the linkage shaft I is connected with the fixed gears {7, 8, III, 12} and the driven ends of the clutches C5968, C3, C11, C59611, C11 and C11 are connected with the idler gears 11, and the clutch C3911;

In order to solve the defects of the traditional problem, the scheme adopts the structure; the fixed gear and the shaft on which the fixed gear is arranged cannot move relatively. The free gear is connected with the shaft on which the free gear is arranged through the clutch, and when the clutch is disconnected, the free gear can rotate relative to the shaft on which the free gear is arranged; when the clutch is engaged, the idler gear moves synchronously with the shaft on which it is located.

preferably, the speed changer further comprises an ECU control unit, wherein the ECU control unit controls hydraulic power to drive the clutch friction plate and the steel plate to be coupled, and any two of the clutches { C1, C2, C3, C4 and C5} are combined to obtain a six-gear speed ratio.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

the gearbox has the advantages of high transmission efficiency, low manufacturing and maintenance cost, compact structure, small gear shifting flow fluctuation, stable gear shifting and large speed ratio coverage range, can meet different operating conditions, and greatly improves the operating efficiency of fracturing equipment.
