Abstract
The invention relates to a safety protection device of laboratory engine bench shafting. The safety protection device comprises a supporting frame (1), a coupling shaft bottom cover (2), a connecting bolt (3), a first flywheel cover (4-1), an intermediate connecting cover (5), a pin (6) and a power measuring end coupling shaft upper cover (7). The power measuring end coupling shaft upper cover and the intermediate connecting cover move reversely along the axis of the pin so that the length of the protection device can be adjusted. The flywheel cover installed on the intermediate connecting cover is replaced so that the flywheel cover is suitable for engines with different flywheel diameters, and thus requirements of different engine bench testing processes towards personal safety are met. Meanwhile, processing cost of introducing new protection devices caused by different sizes of shafting and flywheels is saved. Besides, the flywheel part adopts a half shaft protection mode so that a safety protection effect is realized, and observation of shafting state by operation staffs at parking state is facilitated.
