Abstract
The utility model belongs to the improvement of a component of a drilling machine, which particularly relates to a speed changing device for the cutting part of a drilling machine, and is mainly composed of a cutting head (1), a speed changing device casing (2) and a motor (3), wherein a first shaft (5) is fixedly connected to a shaft of the motor (3) in the speed changing device casing (2), and a first shaft gear (6) is fixed on the first shaft (5); a second shaft coupler (7) is fixedly connected with a second shaft (8), the right side on the second shaft (8) is fixedly provided with a second big shaft gear (10), and the left side on the second shaft (8) is fixedly provided with a second small shaft gear (9); a driving shaft (11) is parallel to the first shaft and the second shaft. The speed changing device for cutting part of drilling machine can be disassembled and replaced according to the properties of coal rock and the conditions of occasions; due to adopting duplicate gears, the utility model uses a shifting fork to change the engaging objects thereof and then are matched with two speeds of a pole changing and speed regulating motor so as to obtain four different rotation speeds of the cutting head, therefore the utility model has high cutting performance and improves the adaptability of the drilling machine.
Description
Technical field
The utility model belongs to the improvement of development machine parts, particularly a kind of tunneling machine cutting portion speed change gear.
Technical background
When the tunneling machine cutting coal petrography, because the complexity of coal petrography condition, constant cutting speed is difficult to adapt to, at present, there is the partial-size tunneling machine cutting motor to adopt double-speed motor, but because power also changes after this variable pole adjustable speed motor speed change thereupon, the not bigger raising of cut moment can't be satisfied the needs that coal petrography changes.
Summary of the invention
The purpose of this utility model ground provides a kind of tunneling machine cutting portion speed change gear that can be applicable to the changeable occasion of coal petrography character in overcoming above-mentioned technical deficiency.
The technical scheme that the utility model technical solution problem adopts is: a kind of tunneling machine cutting portion speed change gear of being made up of cutterhead, motor and reducer shell, be characterized in fixedly connecing No. 1 axle with No. 1 shaft coupling on the motor shaft in reducer shell, on No. 1 axle, fixedly adorn No. 1 shaft gear; With fixedly connected No. 2 axle of No. 2 shaft couplings, a gear wheel is fixedly adorned on the right side on No. 2 axles, and a pinion is fixedly adorned in the left side; Parallelly with No. 1, No. 2 axles adorn a power transmission shaft, the power transmission shaft right-hand member is fixedly adorned one and No. 1 shaft gear meshed gears, the power transmission shaft left end is adorned the duplicate gear of a left and right slip, adorn a shift fork in the middle of the duplicate gear, shift fork has handgrip, duplicate gear respectively with No. 2 axles on big pinion.
The beneficial effects of the utility model are: tunneling machine cutting portion speed change gear can be dismantled and change according to coal petrography character and occasion condition, owing to adopt duplicate gear to change its engagement object with shift fork, cooperate two kinds of speed of variable pole adjustable speed motor can obtain four kinds of different cutterhead rotating speeds again, improve the Cutting Performance of machine, improved the compliance of development machine.
