One-inlet and six-outlet integrated pipe rolling gearbox

Abstract

The invention relates to a gear case special for a one input gear and six output gear integrated rolled tube. The gear case comprises a case body (1), and is characterized in that an idle wheel (5) is installed in the center of the case body (1) and simultaneously meshed with one input gear and five output gears, the input gear is installed on an input gear shaft (4), one end of the input gear shaft (4) is connected with a prime motor, the other end of the input gear shaft (4) is connected with six working rollers, and the five output gears are all installed on corresponding output gear shafts (7); the idle wheel (5) is installed on a water sleeve (6), a core shaft (8) is sleeved with the water sleeve (6), the two ends of the water sleeve (6) are supported on the case wall of the case body (1), a cooling water channel (9) is formed between the inner wall face of the water sleeve (6) and the outer surface of the core shaft (8), and cooling water enters the cooling water channel (9) from a water inlet at one end of the cooling water channel (9) and flows out form a water outlet (11) at the other end of the cooling water channel (9). The gear case is simple in structure, small in size, stable in transmission and high in accuracy.

Description

technical field [0001] The invention relates to a gear box, in particular to a special gear box for a rolling mill with integrated heat dissipation and transmission, specifically a special gear box with one input and six outputs integrated for rolling pipes. Background technique [0002] As we all know, the rolling mill is an important metallurgical equipment, and the rolling mill gearbox is the key equipment to ensure the normal operation of the rolling mill. At present, the rolling mills at home and abroad are all single-stand with gearbox and cooling device structure, which has disadvantages such as large investment, large floor area, high manufacturing cost, and complicated control and adjustment. Therefore, it is necessary to design a new transmission mode. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing rolling mill gear box adopts two sets of cooling device and cooling device to ensure the normal ope...
