Abstract

The invention relates to a sine crank mechanism of a preloaded bearing. According to the mechanism, noise and abrasion can be reduced, and the output precision can be improved. The mechanism comprises a driving rotating disc, an output connecting rod, a frame upper cover plate, a first bearing, a second bearing, a crank cantilever, a frame lower cover plate, guide rails, a connecting part and a base. The mechanism is characterized in that the first bearing and the second bearing are coaxially mounted on the crank cantilever, and the crank cantilever is fixed to the driving rotating disc through nuts; a frame is formed by fixing the frame upper cover plate and the frame lower cover plate to connecting parts through the bolts, and the frame is in sliding connection with the guide rails through the connecting parts; and the output connecting rod is fixed to the frame upper cover plate, and the guide rails are fixed to the base. The mechanism solves the problems that in the revolving process of the mechanism, the crank cantilever strikes the frame to generate noise and abrasion, and consequently, the output sine motion precision is low.

Description

technical field [0001] The invention belongs to the technical fields of mechanical principles and mechanisms, and in particular relates to a pre-tightened bearing sinusoidal crank mechanism capable of reducing noise and wear and improving output precision. Background technique [0002] Crank linkages can be used in many mechanical devices, while sinusoidal crank mechanisms are used to generate regular sine or cosine motion, which can provide standard, periodic excitation for the system. During the actual use of the sinusoidal crank mechanism, the crank cantilever will continuously hit the frame when the frame reciprocates vertically to generate noise, and as the use time increases, dents will appear on the inner surface of the frame, resulting in the oscillatory motion output by the mechanism is not pure sinusoidal or cosine motion. However, not only the current technologies or theories have not attracted attention to this, but no corresponding solutions have been proposed....
