Abstract

The invention discloses an engine air distribution mechanism abrasion testing device, which belongs to engine testing equipment and particularly relates to a device used for the abrasion testing of an engine air distribution mechanism. The engine air distribution mechanism abrasion testing device is characterized in that two mutually parallel upright posts are arranged on a horizontal base, the tops of the upright posts are provided with a cam shaft with a driving device, an upper transverse support frame and a lower transverse support frame used for fixing an air valve air distribution mechanism are arranged between the two upright posts, a guide plate is arranged on the upper transverse support frame, a positioning plate is arranged on the lower transverse support frame, a seat ring seat sheathed on an air valve seat ring passes through a center hole of the positioning plate, a fastening screw nut fixedly arranged at the lower side of the positioning plate is connected with the seat ring seat through screw threads, and an air valve catheter is arranged in an inner hole of the seat ring seat. The testing device has the advantages that the abrasion condition of each part of the engine air distribution mechanism under the actual operation conditions can be completely simulated, and the support is provided for the final design of the engine air distribution mechanism.

Description

technical field [0001] The invention belongs to engine test equipment, in particular to a device for wear test of an engine valve train. Background technique [0002] The gas distribution mechanism of an internal combustion engine is an important part of the engine. It mainly consists of camshafts, tappets, valves, valve seat rings, conduits, springs, spring seats, lock clips, sealing rings and other parts. The main matching surfaces in the gas distribution mechanism are Camshaft and tappet upper surface, valve stem end surface and tappet inner surface, valve stem outer surface and guide tube inner surface, valve cone surface and valve seat ring cone surface, valve lock clip groove and lock clip, seal ring inner surface and The outer surface of the valve stem, these mating surfaces are in high-speed reciprocating motion and high temperature during work and bear a certain spring force, so wear between the mating surfaces is inevitable. When the wear is serious, the power per...
