Abstract
Provided is a rotary power head of a cosine tooth profile drill. A cosine tooth profile transmission speed change gear is formed by an input gear shaft, a big gear and an output shaft, a cover board is fixed on a machine base, a flange is fixed on the cover board, the input gear shaft and a bearing A are supported on the cover board, and the input gear shaft and a bearing B are supported on the machine base. A motor is fixed on the flange and connected with the input gear shaft. The output shaft and a bearing C are supported on the machine base, and the output shaft and a bearing D are supported on the cover board. A joint type forced filling oil cup penetrates through a small end cover of the tail of the input gear shaft to be connected with the input gear shaft. An air inlet hole is arranged on an air chamber, the air chamber is fixed on the machine base, a seal A and a seal B are matched with the air chamber and the output shaft, a radial hole on the output shaft is communicated with the air chamber, and an inner screwed hole is arranged on the output shaft. The rotary power head has the advantages of overcoming the shortcoming of the existing speed reducers and rotary power heads, provides a universal series for speed reducers, and providing a rock drilling machinery rotary power head which is convenient in assembly and disassembly, small in radial sizes, big in delivery torsion and suitability for heavy loads for drilling machines.
Description
Technical field
The utility model relates to a kind of rock drilling machinery part of appliance, is a kind of cosine flank profil rig rotary motive power head specifically.
Background technology
Various rigs are widely used in the engineering explosion hole drill cutter operations such as metallurgy, railway, mine, building materials, highway.Rig rotary motive power head is one of critical component of rig, its speed change gear requires in light weight, barycenter is low, high-speed cutting is bored the rotary motive power head and is required the dynamic equilibrium characteristic good, and gear range is big, but existing universal speed reducer radial dimension is big, do not satisfy instructions for use, movable teeth reducer is a tooth difference eccentric wheel structure, and the dynamic equilibrium characteristic is poor, and the rotary motive power head needs specialized designs.The present invention is a cosine flank profil rig rotary motive power head, and the axle of speed changer is gone into movement parts such as axle and is self-balancing, and gear range is big, uses this rig rotary motive power head, easy accessibility, and transfer torque is big, radial dimension is little, the rock drilling machinery of suitable heavy load.
