Problems solved by technology

The rotary power head of the drilling rig is one of the key components of the drilling rig. Its transmission device requires light weight and low center of mass. The high-speed cutting drill rotary power head requires good dynamic balance characteristics and a wide range of transmission ratios. However, the existing general reducer has a large radial size. Does not meet the requirements of use, the movable tooth reducer is a one-tooth difference eccentric wheel structure, the dynamic balance characteristic is poor, and the rotary power head needs to be specially designed

Abstract

The invention relates to a rotary power head of a cosine tooth profile drilling machine. A cosine tooth profile transmission and speed change device is composed of an input gear shaft, a large gear and an output shaft, a cover plate is fixed on a machine seat, a flange is fixed on the cover plate, the input gear shaft is supported on the cover plate and the machine seat respectively together with a bearing A and a bearing B, a motor is fixed on the flange and connected with the input gear shaft, the output shaft is supported on the machine seat and the cover plate respectively together with a bearing C and a bearing D, a joint type forced filling oil cup penetrates a small end cover at the tail part of the input gear shaft and is connected with the input gear shaft, an air inlet hole is arranged on an air chamber, the air chamber is fixed on the machine seat, 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 internal thread hole is arranged on the output shaft. The invention has the advantages of overcoming the shortcomings of a traditional speed reducer and the rotary power head, providing a universal series for the speed reducer and providing a rock drilling mechanical rotary power head which is convenient to detach and mount, small in radial size, large in transfer torque and applicable to heavy load for the drilling machine.

Description

technical field [0001] The invention relates to a rock drilling mechanical equipment component, in particular to a rotary power head of a cosine tooth profile drilling machine. Background technique [0002] All kinds of drilling rigs are widely used in blast hole drilling operations in metallurgy, railways, mines, building materials, highways and other projects. The rotary power head of the drilling rig is one of the key components of the drilling rig. Its transmission device requires light weight and low center of mass. The high-speed cutting drill rotary power head requires good dynamic balance characteristics and a wide range of transmission ratios. However, the existing general reducer has a large radial size. It does not meet the requirements of use. The movable tooth reducer is a one-tooth difference eccentric wheel structure, with poor dynamic balance characteristics, and the rotary power head needs to be specially designed. The invention is a rotary power head of a ...
