Problems solved by technology

At present, the pickling and passivation of stainless steel products is generally treated with pickling passivation paste or pickling passivation solution. Chemical technology, simple operation, convenient construction, low cost, but it is only suitable for large-scale brushing operations
However, the pickling passivation solution is suitable for the immersion operation of small workpieces, and the process is complicated and the equipment investment cost is large.
[0005] At present, the pickling and passivation treatment applicable to the outer surface of stainless steel coils is mostly treated by brushing pickling passivation paste, and then rinsed. The intermediate turnover period is long, and the manpower and material resources are large. Automated production line, low production efficiency

Embodiment 1

[0022] as attached figure 1 And attached figure 2 As shown, the rotating support frame of the transmission case cover includes a thrust bearing 6 and a radial bearing arranged sequentially from the inside to the outside. Preferably, the radial bearing is a cylindrical roller bearing 5, and the shaft ring of the thrust bearing 6 is sleeved on the At the end of the output shaft 2, the seat ring of the thrust bearing 6 is arranged on the supporting frame body 1, and an adjusting gasket 7 is arranged between the seat ring of the thrust bearing 6 and the supporting frame body 1 of the gearbox.

[0023] The inner ring of the radial bearing is set on the shoulder 4 of the output shaft 2, the left side of the inner ring of the radial bearing is in contact with the output gear 3 of the output shaft 2, and the right side of the inner ring of the radial bearing is in contact with the thrust bearing The shaft rings of 6 are against each other, and a gasket 8 is arranged between the inne...

Embodiment 2

[0028] The passivation production line of the rotating support frame of the gearbox case cover arranges the incoming material inspection workbench, pickling equipment, washing liquid tank, testing platform and drying equipment in sequence according to the process, and the equipment is connected by a transmission roller. The pickling equipment adopts a pickling liquid tank, and the workpiece is dipped to remove the oxide layer. The upper part of the pickling liquid tank is equipped with a liquid inlet pipe, and the side wall of the tank body is equipped with a liquid discharge pipe. The liquid inlet pipes are respectively connected to the pickling liquid source. The liquid outlet pipe is connected to the liquid discharge device, and the pickling liquid is recycled.

Embodiment 3

[0030] The passivation production line of the rotating support frame of the gearbox case cover arranges the incoming material inspection workbench, pickling equipment, washing liquid tank, testing platform and drying equipment in sequence according to the process, and the equipment is connected by a transmission roller. The pickling equipment adopts a spraying machine, and the lower part of the spraying machine is equipped with a liquid receiving tank, and the workpiece is sprayed with pickling passivation paste to remove the oxide layer.

[0031]When adopting embodiment 2 or embodiment 3 production line to clean, press incoming material inspection--spray (rolling brush) passivation solution-clean water flushing-check-drying operation, at first on the incoming material inspection workbench All incoming materials are inspected to ensure that the rotating support frame should be free from welding slag, cracks, severe scratches and other mechanical damages, so as to meet the pickl...

Abstract

The invention relates to the technical field of gearboxes, and discloses a rotary supporting frame for a gearbox box cover. A transverse cavity and a vertical cavity are arranged in a supporting framebody, wherein the transverse cavity communicates with the vertical cavity; an opening which communicates with the outer part is formed in the vertical cavity; the opening is positioned at the outer ring of a radial bearing; a first wedge block is in sliding connection in the vertical cavity; a groove for inserting the first wedge block is formed in the outer ring of the radial bearing; a spring is connected between the first wedge block and the vertical cavity wall; a second wedge block which abuts against the first wedge block is in sliding connection in the transverse cavity; a bolt is in threaded connection on the supporting frame body; and the bolt extends into the transverse cavity, and abuts against the second wedge block. In order to solve the problem that the supporting frame bodyis worn by the outer ring of a cylindrical roller in the prior art, the first wedge block and the second wedge block are arranged, so that the second wedge block drives the first wedge block to slideinto the groove by screwing up the bolt, and the first wedge block also abuts against the bottom wall of the groove, and therefore, the outer ring of the radial bearing is fixed, and the supporting frame body is prevented from being worn by the radial bearing.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a rotating support frame and a passivation production line for a gearbox case cover. Background technique [0002] One end of the output shaft of the automatic transmission is connected to the planet carrier, and the other end is installed on the transmission case through a rotating support frame. The output shaft is provided with a shaft shoulder and an output gear sequentially from the inside to the outside. The rotating support frame includes a support frame body and a bearing group. The bearing group includes a cylindrical roller bearing mainly for bearing radial force and a thrust bearing mainly for bearing axial force. The cylindrical roller bearing is installed on the shaft shoulder. A gasket is arranged between the outer ring of the roller bearing and the supporting frame body, the thrust bearing is located at the end of the output shaft and an adjusting gasket is arran...
