460-type wheel excavator wheel side reducer shaft head shaft improvement Zhongyuan Oilfield oil construction company Liu Yunhuan, 40 wheel excavator wheel reducer for planetary gear ring gear and ring gear seat and other components. The gear is connected to the ring gear seat by splines and the ring gear seat is connected to the rear axle case by splines. The planet gear meshes with the sun gear and the ring gear, and is mounted on the planet carrier through the needle roller and the planet axle, which drives the planet carrier to rotate. The planet carrier also drives the reducer shell and the wheels to rotate. This structure has many advantages. The gear ratio is suitable and the torque obtained is large. However, in the repair, I often encounter the problem that the shaft head of the wheel reducer housing is easy to loosen and the oil leaks. After analysis and research, the repair and repair of the scrapped shell shaft head is introduced. 5 is fixed to the planet carrier 3 with 6 PCT 6 bolts, sealed with a flat asbestos plate, and the planetary carrier 3 is fixed to the wheel reducer housing 7 with 412 steady pins and 62 bolts, and the plane asbestos plate seal is still used. . 1.6 Bolts 24. Asbestos gaskets 3. Planetary carrier 5. Axle head cover 6.602 Bolts 7. Wheel reducer housing The power transmission mechanism of this mechanism transmits the torque to the sun wheel, the sun wheel and the planet from the axle of the rear axle. The wheels mesh with each other, and the planetary gear meshes with the ring gear. Because the ring gear is connected with the rear axle housing by the spline, it is fixedly secured to the wheel reducer housing through a 4¢12 stabilizing pin and 6M12 bolts. The side reducer housing is fixed on the rim, so power is transmitted from the planetary wheels to the rim tires to drive the wheels to rotate. The disadvantages of this structure are the low reliability of sealing with flat asbestos plates; the planetary carriers are subjected to great force, while the fixed planetary carrier construction machinery is covered by a 2000-axis head cover and cannot be fastened in time, so the planetary carrier can only be The more ambiguous, the 4012 steadily pinned the hole into a ring shape, which caused the wheels to begin leaking oil. Finally, the pin hole had to be expanded to at least 14. After a period of time, the above-mentioned problem still occurred. When the hole was reamed at least 16 hours, the hole could no longer be reamed. Only the planetary carrier and the wheel reducer housing can be scrapped, resulting in higher repair costs and lower equipment availability and utilization. Modifications to 2, Planetary gear wheel reducer 1.1242 Bolts 2. Spring washers 3. Conical spring washers 4. 5.0 Type seal 6. Axle head cover 7. Planetary carrier 8. Wheel reducer housing shell Based on the original structure, the original bolt holes are welded and the flat ends are replanned. Drill holes are redesigned, and the axle head cover is painted and manufactured according to the requirements of the new design structure. The steady pin position of 412 is retained, and the original position is fixed. Method 6M12 Bolt-fixed planet carrier 6M6 screw fixed shaft head cover, changed to 12M12 bolt strength class 19 fixed axle head cover and planetary gear carrier on the wheel reducer housing, and installed in the screw hole of the shaft head cover, 20 Conical spring retraction pads for axle heads are used to prevent bolts from loosening. In addition, two slots are turned on the axle cap carrier and two are installed. The ring edge is 2213.102724. Joints. The advantage of this improvement is the increased fastening of the connection and increased reliability. Even if the bolt is loose, it can be fastened at any time, simplifies the maintenance procedure and is more convenient for maintenance; replacing the asbestos plate sealing end face with two 0-ring seal end faces improves the reliability of the seal, even if the bolt is slightly loosened Trolley Cargo,Cargo Trolley For Sale,Folding Cargo Trolley,Cargo Push Cart Guangdong Gongyou Lift Slings Machinery CO.,LTD , https://www.workmateslift.com
