Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, the present invention includes a housing 4 with a cavity, and an eccentric shaft 10 located in the cavity of the housing 4, a pair of gears with few tooth differences and a plunger cylinder stepping drive assembly, and the plunger cylinder stepping drive assembly drives less The tooth difference gear pair rotates in the plane, and the plunger cylinder stepping drive assembly provides power for the small tooth difference gear pair.
[0024] Such as figure 1 As shown, the eccentric shaft 10 is mainly composed of the main shaft section located at both ends and the eccentric shaft section located between the main shaft body. The main shaft section at both ends of the eccentric shaft 10 is integrally formed with the middle eccentric shaft section. A cylindrical roller bearing 7 is hingedly mounted on the housing 4 , and the outer wall of ...

The invention discloses a heavy-duty combined type stepping actuating mechanism. A small tooth difference gear pair and a plunger type cylinder stepping driving assembly are mounted at the periphery of an eccentric shaft. The eccentric shaft is mounted on an inner ring of an outer engagement gear in a sleeving manner. An output end inner engagement gear is mounted on an outer ring of an outer engagement gear outer ring in a sleeving manner. Outer ring teeth of the outer engagement gear are engaged with inner ring teeth of the output end inner engagement gear to form the small tooth differencegear pair. The output end inner engagement gear serves as the power output of the actuating mechanism. All the plunger type cylinder eccentric shafts of the plunger type cylinder stepping driving assembly are uniformly distributed in a spaced manner in the circumferential direction. Plunger levers are arranged in the radial direction of the eccentric shafts. Each plunger type cylinder is connectedto the side face of the outer circumference of the corresponding eccentric shaft. Each plunger type cylinder is connected to an oil supply device and an oil tank through a two-position three-way solenoid valve. Ports of the two-position three-way solenoid valves are switched through a controller, so that control over each plunger type cylinder is achieved. By means of the heavy-duty combined typestepping actuating mechanism, compared with servo motor output, the torque is remarkably increased, and the size is decreased; and compared with common hydraulic output, the precise stepping output can be achieved.
Description
technical field [0001] The invention belongs to the field of step-type compound transmission, and specifically relates to a step-type actuator with high load-carrying capacity, which is composed of a pair of internal meshing gears with less tooth difference, an eccentric shaft, a plunger cylinder, a controller, a power amplifier, and the like. Background technique [0002] Stepping actuators generally refer to transmission devices that can convert existing mechanical energy, electrical energy or other energy forms into target stepping motion forms through certain specific mechanical transmission structures. At present, various types of actuators based on motors can easily realize step-by-step control by combining corresponding reducers. However, the power density of the motor is low. To achieve real high power output, the micro motor obviously cannot meet the conditions. The traditional hydraulic actuator uses pressure oil as the power source of the actuator. Compared with ...
