Problems solved by technology

[0002] The gear transmission of the existing product adopts a transmission mode of a steel gear and a nylon gear. The advantages of this transmission mode are stable transmission, low noise, and stable output torque; after using it for a period of time, we found that this There is a big defect in the transmission. When the load of the machine tool is too large, or when the cutting direction is changed, the nylon gear is easily damaged, which greatly reduces the safety performance of the machine tool.

Abstract

The invention relates to a drilling machine head box. A transmission device comprises a steel gear (1) and a nylon gear (2) which are matched, the nylon gear (2) comprises an inner sleeve (21) and anouter gear (22), the inner sleeve (21) is made of nylon, and the outer gear (22) is made of the nylon and fiberglass. According to the drilling machine head box, the nylon gear is arranged in a splitmode, namely the inner sleeve and the outer gear, wherein the outer gear is made of the nylon and the fiberglass, in this way, the strength and abrasion resistance of the nylon gear are enhanced, theservice life of the nylon gear is prolonged, meanwhile, the structural form of the inner sleeve and the outer gear is adopted, the using cost of the nylon gear is also lowered, and the economical efficiency is quite good.

Description

technical field [0001] The invention relates to a head box of a drilling machine, which belongs to the technical field of drilling machines. Background technique [0002] The gear transmission of the existing product adopts a transmission mode of a steel gear and a nylon gear. The advantages of this transmission mode are stable transmission, low noise, and stable output torque; after using it for a period of time, we found that this There is a big defect in the transmission. When the load of the machine tool is too large, or when the cutting direction is changed, the nylon gear is easily damaged, which greatly reduces the safety performance of the machine tool. Contents of the invention [0003] The purpose of the present invention is to provide a drill head box with reasonable structure and greatly improved service life of gears. [0004] To this end, the technical solution adopted by the present invention is: the present invention includes a transmission device, the tra...
