Problems solved by technology

In addition, due to the influence of the swing angle error, the range of the swing angle, the size of the mechanism, and the angular velocity of the main and driven parts of the cam mechanism are greatly limited, and its bearing capacity is relatively poor.

Abstract

The invention provides a movable tooth cam mechanism capable of achieving single-shaft constant-speed input and double-shaft variable-speed swing output, and belongs to the technical field of mechanical transmission. The mechanism comprises an input shaft, an input plate, inner steel balls, outer steel balls, a movable tooth rack, an inner swing plate, an outer swing plate, an inner output shaft, an outer output shaft and a machine frame. The input shaft and the input plate are fixedly connected into a whole to constitute a shock wave device. The movable tooth rack is fixedly connected to the machine frame. The inner steel balls are evenly distributed in inner radial grooves distributed in the movable tooth rack in the circumferential direction respectively and are located in interlacing areas of an inner transverse tooth profile groove of the input plate and transverse tooth profile grooves of the inner swing plate respectively all the time, and the outer steel balls are evenly distributed in outer radial grooves distributed in the movable tooth rack in the circumferential direction respectively and are located in interlacing areas of an outer transverse tooth profile groove of the input plate and transverse tooth profile grooves of the outer swing plate respectively all the time. The inner swing plate is fixedly connected with the inner output shaft, and the outer swing plate is fixedly connected with the outer output shaft. Through the movable tooth cam mechanism, single-shaft constant-speed input and double-shaft simultaneous variable-speed swing output can be achieved, and the swing direction, the swing angle, the swing law and the bearing capacity can be combined according to practical situations; on the premise that using conditions are met, the functions of the mechanism are maximized.

Description

technical field [0001] The invention relates to a movable-tooth cam mechanism with single-axis constant-speed input and double-axis variable-speed swing output, belonging to the technical field of mechanical transmission. Background technique [0002] In many aspects such as textile machinery, printing machinery, agricultural machinery, and automated office equipment, there is a particularly large demand for specific and regular oscillating motions, and these oscillating motions are mostly realized by means of cam mechanisms. In some cases where multiple sets of swing motions are required, the requirements have to be met by increasing the number of cam mechanisms. In addition, due to the influence of the swing angle error, the range of the swing angle, the size of the mechanism, and the angular velocity of the main and driven parts of the cam mechanism are greatly limited, and its bearing capacity is relatively poor. Therefore, it is particularly important to design a mecha...
