Abstract
The utility model relates to a cam transmission part of a universal breaker operating mechanism. The cam transmission part comprises a main spring and a cam disc. The cam disc may compress the main spring in order to store energy or release the main spring in order to perform brake closing control. The main spring is capable of pressing a rotating arm mounted on the main shaft of a breaker to rotate by using a connecting rod in order perform brake closing operation. A cam is disposed on the cam disc. A roller abutted against the cam is mounted on the edge of the rotating arm. A position-limiting block opposite to the cam surface on the edge of the cam is disposed on the cam disc and is arranged on the back side of the highest point of the edge of the cam. A position-limiting channel is formed between the position-limiting block and the cam surface on the back side, wherein the roller may pass through the position-limiting channel and the position of the roller is limited by the position-limiting channel. The cam transmission part increases the operative reliability of the entire mechanism in the closing process and has characteristics of a simple structure and easy manufacture and installation.
Description
Technical field
The utility model relates to low voltage power transmission equipment, specifically is a kind of cam drive parts of universal circuit breaker operating mechanism.
Background technology
The cam drive parts of existing omnipotent breaker operating mechanism as shown in Figure 1, generally include to provide the main spring 01 of power and main spring is carried out compressed energy-storage or the cam disc 02 of the control of discharge closing a floodgate for combined floodgate; Press pivoted arm 04 rotation that is installed on the circuit breaker main shaft by connecting rod 03 when main spring discharges, carry out closing operation; Cam disc 02 is provided with cam 05, and the pivoted arm edge is equipped with the roller 06 that is pressed on the cam; In the cam rotary course, when roller relatively moves to the peak of cam (state shown in the accompanying drawing 1), the compressed energy storage of main spring, and roller is crossed the cam peak and when separating, and the main spring abrupt release, driving mechanism closes a floodgate.For after preventing cam and roller separating, rotational angle is excessive, generally is the huge thrust that relies on transmission mechanism to transmit, in the rotary part generation frictional force of cam, thus the lock cam braking.And in case because foozle or product wear and tear, this frictional force reduces, and may cause cam to change more, and this will cause the operating grip ratchet that is connected with cam to contact in advance with ratchet, and handle can not freely be pulled out a segment distance, influences user's manual operation.If rotational angle is more, can cause main spring to fail to push away connecting rod and put in place, and the too early ascending curve by cam blocks, and can not turn round, thereby cause false combined floodgate phenomenon, influence the reliability service of mechanism.
Summary of the invention
Technical problem to be solved in the utility model is, cam drive parts to existing omnipotent breaker operating mechanism improve, provide a kind of can carry out cam reliably spacing, prevent that cam from rotating the position in making process, and the cam drive parts of simple in structure, manufacturing and universal circuit breaker operating mechanism easy for installation.
The cam drive parts of omnipotent breaker operating mechanism of the present utility model include main spring and main spring are carried out compressed energy-storage or discharges the cam disc that closes a floodgate and control; Main spring can press the pivoted arm rotation that is installed on the circuit breaker main shaft by connecting rod, carries out closing operation; Cam disc is provided with cam, and the pivoted arm edge is equipped with the roller that is pressed on the cam; In the cam rotary course, when roller relatively moved to the peak of cam, main spring can compressed energy storage, and roller is crossed the cam peak and when separating, and main spring can abrupt release, and driving mechanism closes a floodgate; Described cam disc is provided with a guide vane end stop relative with the cam surface of cam edge, guide vane end stop is positioned at the dorsal part (being the d/d side of roller) of cam edge peak, forms one between the cam surface of guide vane end stop and described dorsal part and can pass through the also limit channels of relative limit with making roller.
Described guide vane end stop is elastomeric material, as elastomeric material etc.
The utility model is by increasing guide vane end stop at cam disc, make in the making process, its outside can be spacing mutually with guide vane end stop after roller was crossed the cam peak, can produce an additional damping to the continuation transhipment of cam, thereby prevented that cam from rotating the position, improved the reliable in action of entire mechanism, and its simple in structure, manufacturing and easy for installation.
