Device for testing moment limiters.

摘要

The invention refers to a device for testing moment limiter couplings, intended for measuring and adjusting the load of those subsets, used for certain rotary and/or percussive rotary electric tools. According to the invention, the device for testing moment limiter couplings has a working shaft (2) and a load shaft (3) which rest on the support-frame (1) via angular bearings (4 and 5). At the external end of the working shaft (2), a moment limiter coupling (7) is mounted, and at the other end, a moment sensor (8) is positioned, connected to the amplifier (14). The coupling (7) engages a quadrant (a) of a sleeve (13) fixed on the load shaft (3). On the same load shaft (3), forming one piece with it, there are also a disc clutch (10) and a worm wheel (11) of a worm gear (A) which can be operated from a hand-wheel (9).
