Description

Novel cutting part and heading machine

Technical Field

The utility model relates to a heavily be good at equipment technical field, especially relate to a novel cutting units and entry driving machine.

Background

At present, the cutting part of the traditional heading machine at home and abroad adopts a transmission mode that a motor drives a two-stage planetary gear transmission and then drives a main shaft of a cutting head to rotate.

The working principle of the cutting part driving mechanism of the traditional heading machine is as follows: the motor drives the two-stage planetary gear transmission to work through the coupler, the transmission drives the main shaft to rotate through the spline shaft and the spline sleeve, so that the cutting head assembled on the main shaft is driven to rotate, cutting teeth arranged on the cutting head extrude and crush rocks through rotary motion, and the rock stratum tunneling function is achieved.

The traditional driving mode is used for many years, and firstly, the two-stage planetary gear transmission is heavy in transmission load and high in noise; energy is converted and transmitted through the two-stage gear set, so that the efficiency is low and the energy consumption is high; thirdly, the requirement on the lubrication of the two-stage gear set is high, and the gear is often damaged due to poor lubrication; and fourthly, the overload impact resistance of the gears in the two-stage gear set is not strong, once hard rocks (which often occur when faults occur in actual production) are clamped in broken rock stratums, a control system does not react timely, the gear set can bear impact overload, the gear surface of the gear is damaged slightly to cause unstable operation and increased noise, the gear is broken seriously, and the production is interrupted due to equipment failure. And energy is converted and transmitted through a gear set, and due to the limitation of installation space, the working capacity of a gear set transmission is limited, so that the peak torque force of the cutting head is limited, and harder rock cannot be crushed (generally, granite cannot be directly crushed). Sixthly, the working rotating speed of the cutting head of the traditional heading machine is 1 to 2 fixed rotating speeds, and the traditional heading machine cannot be adjusted and applied when the actual rock cutting needs lower or higher rotating speed.

SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem that will solve provides a novel cutting units and entry driving machine to make promotion torsion and noise reduction.

In order to solve the technical problem, the embodiment of the utility model provides a novel cutting unit is provided, including cutterhead, main shaft, spline housing, single-stage planetary gear derailleur, shaft coupling and motor, the motor comprises motor stator, electric motor rotor, and electric motor rotor, shaft coupling, single-stage planetary gear derailleur, spline housing, main shaft, cutterhead link to each other in proper order.

Further, the motor is a high-torque permanent magnet motor.

Correspondingly, the embodiment of the utility model provides a still provide a heading machine, including foretell novel cutting units.

The utility model has the advantages that: the utility model discloses a rotatory broken doing work of single-stage planetary gear derailleur drive cutterhead, single-stage planetary gear derailleur compare two-stage planetary gear derailleur energy conversion efficient, and torsion is bigger, and the quiet noise of operation is little, has more significantly reduced the defect that two-stage planetary gear derailleur leads to the gear to collapse when because of broken stereoplasm fault. The working rotating speed of the cutting head realizes stepless speed change, so that the cutting efficiency can be better improved, and the application range of the heading machine can be expanded.
