Abstract
The utility model discloses a tile frame and positioning pin integrated main shell reducing assembly, which comprises a main shell reducing and two tile frames, wherein the two tile frames and the positioning pin are integrally cast, and the positioning pin is connected with a pin seat in an axle housing; the main reducing shell and the tile frame are connected through bolts. The utility model discloses a change main reducing shell assembly support means, close locating pin and tile frame as an organic whole, realized simplifying the technology, and improved the stability of main reducing shell assembly to guarantee main reducer's reliability.
Description
Technical Field
The utility model relates to a main reducing shell assembly of tile frame locating pin integration belongs to automobile parts technical field.
Background
At present, the main reducer shell assembly of the domestic drive axle main reducer is insufficient in stability and low in rigidity, and a tile frame is easy to deform in the using process, so that oil leakage is caused, even a main bevel gear and a driven bevel gear are damaged, and the service life of the main reducer is shortened. Most main reducing shell assembly is fixed with the axle housing through four angles of two tile framves, perhaps two tile framves middle part are equipped with blind hole assembly locating pin and are connected with axle housing pinhole, improve main reducing shell assembly's rigidity (as shown in figure 2). However, in the former, if gaps are slightly formed between four corners of the tile frame and the axle housing, the tile frame can deform; the positioning pin has the disadvantages of complex assembly of a plurality of parts and low production efficiency.
Disclosure of Invention
The utility model aims to solve the technical problem that to the defect that prior art exists, a main reducing shell assembly of tile work locating pin integration is provided.
In order to solve the technical problem, the utility model provides a main shell reducing assembly with integrated tile frame and positioning pin, which comprises a main shell reducing and two tile frames, wherein the two tile frames and the positioning pin are cast integrally, and the positioning pin is connected with a pin seat in an axle housing; the main reducing shell and the tile frame are connected through bolts.
The diameter of the positioning pin is 20-50 mm.
The main reducer casing is connected the face with the axle housing and is equipped with the circle tang, circle tang and axle housing cooperation.
The height of the round spigot is 5-15 mm.
Has the advantages that: the utility model discloses a change main reducing shell assembly support means, close locating pin and tile frame as an organic whole, realized simplifying the technology, and improved the stability of main reducing shell assembly to guarantee main reducer's reliability.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of a prior art main reduction housing assembly.
In the figure: 1 main reducing shell, 2 tile frame, 3 bolts, 4 round rabbets, 5 locating pins, 6 snap rings and 7 pin bosses.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
The utility model provides a tile frame positioning pin integrated main shell reducing assembly, which comprises a main shell reducing 1 and two tile frames 2, wherein the two tile frames 2 and a positioning pin 5 are integrally cast, and the positioning pin 5 is connected with a pin boss 7 in an axle housing; the main reducing shell 1 and the tile frame 2 are connected through bolts 3.
The diameter of the positioning pin 5 is 20-50 mm.
The main reducing shell 1 is connected the face with the axle housing and is equipped with circle tang 4, circle tang 4 and axle housing cooperation.
The height of the round spigot 4 is 5-15 mm, and the main speed reducer is supported within the circumferential range.
The two tile frames 2 and the positioning pin 5 are integrally cast, the positioning pin 5 and the snap ring 6 are reduced, the supporting mode of the main reducing shell assembly is improved, and the round seam allowance 4 is additionally arranged on the connecting surface of the main reducing shell and the axle housing to be matched with the axle housing; and the positioning pin 5 and the tile frame 2 are integrated, so that the assembly process is simplified, the production efficiency is improved, and the stability of the main reducer shell assembly is improved, thereby ensuring the reliability of the main reducer.
The above embodiments of the present invention are merely examples, not the only ones, and all changes within the scope of the present invention or the same range of the present invention are all surrounded by the present invention.
