Abstract

The invention discloses a 75t heavy forklift truck half axle which is characterized by comprising a half axle body (1), a half axle flange (2), a flange disk matching surface (3), a positioning pin hole (4), a high-frequency quenching region (5), a flange disk center hole (6), bolt holes (7), a flange disk neck part (8), a spline shaft (9), a spline quenching region (10), a spline tooth (11), a center hole (12) and a detaching screw hole (13), wherein the bolt holes (7), the positioning pin hole (4) and the detaching screw hole (13) are formed in the end part of the half axle flange; eight bolt holes (7) are uniformly formed in the flange disk matching surface, and the aperture of each bolt hole is 14.5mm; the positioning pin hole (4) and the detaching screw hole (13) are formed in the flange disk matching surface; an included angle between the positioning pin hole (4) and the detaching screw hole (13) is 90 degrees; the high-frequency quenching region (5) is arranged at the root of the flange disk neck part; a quenching layer is 1.5mm deep, and the hardness HRC is 45; a high-frequency quenching layer of the spline quenching region on the spline shaft (9) is 2mm deep, and the hardness HRC is 47.

Description

Technical field [0001] The invention relates to a forklift axle, in particular to a 75t heavy forklift axle. Background technique [0002] Forklifts play a very important role in the company's logistics system and are the main force in material handling. It is widely used in various sectors of the national economy such as stations, ports, airports, factories, warehouses, etc. It is an efficient equipment for mechanized loading and unloading, stacking and short-distance transportation. my country began to manufacture forklifts in the 1950s. Especially with the rapid development of China's economy, the material handling of many companies has been separated from manual handling and replaced by forklift-based mechanized handling. Therefore, in the past few years, the demand for forklifts in China has doubled every year. At present, there are many forklift brands on the market and their models are complex, which causes problems faced by more purchase companies. What's more importan...
