偏心轮推杆滚柱活齿内齿轮齿廓型面连接的凿岩转钎机构制造技术

一种偏心轮推杆滚柱活齿内齿轮齿廓型面连接的凿岩转钎机构，包括齿轮套、钎尾和连接套，齿轮套与连接套采用偏心轮推杆滚柱活齿内齿轮齿廓型面连接，连接套与钎尾采用偏心轮推杆滚柱活齿内齿轮齿廓型面连接或花键连接。本发明专利技术的优点是：本发明专利技术的独立回转导轨式凿岩机转钎机构克服了现有凿岩机转钎机构采用花键连接存在的不足，将偏心轮推杆滚柱活齿内齿轮齿廓型面应用于转钎机构连接面，为凿岩机提供一种自动定心能力强，拆装方便，消除应力集中，配合截面形状简单的传递扭矩大、适合重载荷的转钎机构，特别适合于独立回转导轨式凿岩机。

Rock drilling and rotating mechanism for connecting eccentric roller, push rod, roller, movable gear, inner gear, tooth profile

An eccentric wheel and push rod roller movable tooth inner gear profile connection drill rotational mechanism, including gear sleeve, shank and connecting sleeve, gear wheel and push rod sleeve and a connecting sleeve roller movable tooth inner gear profile is connected with the connecting sleeve and the eccentric shank with eccentric wheel and push rod roller movable teeth gear tooth profile connection or spline connection. The advantages of the invention are: independent rotary rail type drilling machine of the invention rotational mechanism overcomes the shortcomings of existing drilling machine rotational mechanism using spline connection exists, the eccentric wheel and push rod roller movable tooth inner gear profile for rotational mechanism connecting surface for drilling machine provides a self centering capability, convenient assembly and disassembly, eliminate stress concentration, simple transmission torque, rotating mechanism suitable for brazing heavy load section shape with, especially suitable for independent rotary drill guide.
