Embodiment Construction

[0020] like figure 1 As shown, the torque limiter includes a hub 40 keyed to the main shaft 32 , a connecting piece 41 as a transmission member, and three fasteners 52 . The torque limiter is arranged on the power transmission path between the automobile engine and the air conditioner compressor. A pulley 30 serving as a drive of the compressor is mounted on a front cylinder head 60 of the compressor through a bearing 31 . The torque limiter is arranged between the pulley 30 and the main shaft 32 of the compressor to transmit the torque of the pulley 30, and the function of the torque limiter is to cut off the transmission of the torque when the load is too large.

[0021] like figure 2 As shown, the connecting piece 41 is arranged between the hub 40 and the pulley 30, and it includes a circular ring 42 with a substantially circular shape. There are three arc-shaped connecting arms in the same direction (substantially parallel) on the outer peripheral side of the circular ...

Abstract

The object of the present invention is to provide a torque limiter with simplified structure and a compressor including it. Wherein the torque limiter includes a first rotating member and a second rotating member, and a rotation transmitting member connecting the first rotating member and the second rotating member, and the rotating transmitting member includes a plurality of connecting arms, and the connecting arms extend along a circumferential direction. Distributed at intervals, each connecting arm includes a root and an end respectively arranged on both sides along the circumferential direction, the root is connected to the first rotating member, and the end is detachably connected to the second rotating member, and the characteristics are: The second rotating member has a body and a folded portion, the folded portion is bent from the outside to the inside of the second rotating member, the end is clamped between the folded portion and the body of the second rotating member, and the end and The second rotating parts are also matched by means of bosses and engaging holes.

Description

technical field [0001] The present invention relates to power transmission devices for rotating machines, and more particularly to a torque limiter that disconnects when the compressor is overloaded. Background technique [0002] Torque limiters are used in many applications, such as in the power transmission path of automobile engines and compressors used in air conditioning. A typical externally controlled variable displacement compressor has a swash plate supported obliquely on the main shaft, and the angle of the swash plate can be changed by the electric control valve of the compressor. When the internal failure of the externally controlled variable displacement compressor increases the torque, the excessive torque will have a great impact on the engine. Therefore, the compressor must have an overload protection mechanism, so that when the internal torque of the compressor is too large, the compressor is separated from the pulley, so as to avoid the impact of the exces...
