Stepping blade type robot joint

Abstract

The invention discloses a stepping blade type robot joint. The stepping blade type robot joint comprises a left end cover, a rolling bearing, a central spindle, child blades, mother blades, an inner meshing gear pair, a needle bearing, a side plate, an oil distribution disc, a right end cover, a rotary oil distribution valve and a stepping motor; the inner meshing gear pair comprises an outer gearcapable of doing planar motion and an inner gear fixed to a central shaft; the central spindle is arranged in the outer gear, can not rotate and is provided with blade grooves and opening grooves; the right end cover is provided with oil ports of an oil supply way and an oil return way, and oil is supplied to oil cavities sequentially through the rotary oil distribution valve; the rotary oil distribution valve is driven by the stepping motor to rotate; and the oil ways sequentially supply oil to the oil cavities, an outer gear small gear is pushed to do planar motion, an inner gear large gearis driven to rotate, and power output is achieved. The stepping blade type robot joint has the advantages of being high in precision, large in output power density and compact in structure.

Description

technical field [0001] The invention relates to the field of mechanical joints, in particular to a stepping vane robot joint combined with hydraulic pressure and gear transmission. Background technique [0002] With the development of robot technology, the requirements for robot arms are also constantly increasing. Robot arms are required to have high precision, fast response, low energy consumption, low energy consumption, small size, light weight, large torque, and strong carrying capacity. features. There are mainly two drive modes for the drive joints of the existing robot arms, which are divided into single drive drive and compound drive structure. Traditional motor drive, steering gear drive and hydraulic drive, as well as new memory combination, piezoelectric ceramic and other drives are all driven by a single driver. However, it is driven by a single driver without a transmission mechanism, so that it cannot achieve a relatively large driving torque. The joints of...

Problems solved by technology

However, it is driven by a single driver without a transmission mechanism, which makes it impossible to achieve a relatively large driving torque.

The joints of the composite drive structure can provide a larger torque, but the composite drive structure is more complicated, the operation is cumbersome, the sensitivity is low, and in some cases there are still shortcomings of insufficient precision.

In the existing technology, the drive of the robot arm still has the problem that heavy load and high precision cannot be guaranteed at the same time
