[0005] The arc radius of the reinforcement ring 5 is 0.1-0.2 mm larger than the radius of the support shaft 1 and the bridge housing 2 .
[0006] The reinforcing ring 5 has an arc angle of 120° and is manufactured by cutting a circular ring into three reinforcing rings to improve the utilization rate of materials.
[0007] The reinforced heavy-duty loader drive axle housing of the above structure can effectively improve the strength of the ring weld of the axle housing by improving the design of the axle housing, and has the following technical characteristics and beneficial effects:
[0008] 1. By adding a reinforcing ring at the welding point between the supporting shaft 1 of the bridge housing and the bridge housing 2, the connection strength at the weld is effectively improved, so that the drive axle can better adapt to the heavy-load working conditions of the whole machine.
[0009] 2. The arc angle of the reinforcement ring 5 is 120°, and one circular ring can be cut into three reinforcement rings, so the material utilization rate is high.
[0010] 3. Simple and compact structure, easy to manufacture, low maintenance cost, safe and reliable operation, and long service life; BRIEF DESCRIPTION OF THE DRAWINGS
