Turning mechanism of four-legged walking machinery

Abstract

The invention provides a turning mechanism of a four-legged walking machinery. The turning mechanism comprises a front rotating platform, a back rotating platform, a turning motor, a shaft coupling, a screw rod and a threaded tube, wherein the front rotating platform and the back rotating platform respectively comprise upper and lower layers of iron sheets which are riveted with each other; plane bearings are mounted in the middle of the upper and lower layers of iron sheets; the turning motor is fixed on the upper layer of iron sheet of the front rotating platform by a bolt; one end of the screw rod is connected with the turning motor by the shaft coupling while the other end of the screw rod matches with the threaded tube; the lower layers of iron sheets of the front rotating platform and the back rotating platform are respectively screwed with a front bracket and a back bracket of the four-legged walking machinery by nuts; and the threaded tube is fixed on the upper layer of iron sheet of the back rotating platform. The turning mechanism of the four-legged walking machinery, provided by the invention, has the advantages of simple structure, flexibility for turning, easiness for mounting and control, constant turning speed and high stability of the whole machine; and the flexibility for turning and the turning speed are controllable through controlling the rotation speed of a motor.

Description

technical field [0001] The invention relates to a turning mechanism of a quadruped walking machine driven by a single motor. Background technique [0002] The turning problem of turnable quadruped walking machinery has always been a technical difficulty. To realize the turning function, the combination of mechanical steering and power steering is required. Multi-motor-driven quadruped walking machinery can adjust the speed of the front two legs to achieve turning, but single motor Just be difficult to realize turning function. Contents of the invention [0003] Aiming at the problem of difficult and inflexible turning of the current quadruped walking machinery, the invention proposes a turning mechanism of the quadruped walking machinery driven by a single motor with simple structure, convenient installation and stable operation. [0004] The turning mechanism of the quadruped walking machine of the present invention is characterized in that: it comprises a front rotating...
