Embodiment Construction

[0012] A limiting device for an engine crankshaft. As shown in the accompanying drawings, the crankshaft bearing assembly 4 is installed at the rotary journal of the crankshaft 3. The crankshaft bearing assembly 4 is a detachably connected sliding bearing, which is fixed on the engine body 1 It consists of a bearing pad and a bearing gland. The crankshaft 3 has two ends, one of which is fixed with a flywheel 6, and this end is connected with the clutch to output power externally; the other end is fixed with a pulley 7 for internal output power, and the pulley 7 is located on the outside of the engine body 1 , the connecting flange connecting the pulley 7 and the crankshaft 3 axially abuts against the outer end surface of the timing gear 2 . The first thrust ring 5 and the second thrust ring 5' are arranged on a crankshaft bearing assembly 4 closest to the flywheel 6, and the first thrust ring 5 is arranged in the depression of the end surface of the crankshaft bearing assembly...

Abstract

The invention discloses a limit switch device of engine bent axle, which is characterized by the following: arranging axial caging device; restricting the bent axle to run toward belt pulley end; setting the axial caging device as ball bearing to bear axial force, stopping push plate and top depend device; assembling the ball bearing in assembled hole of the belt pulley; assembling the stopping push plate in inner ring hole of the ball bearing; fixing the top depend device on the outside of the engine body; top-depending the out ring inner side end face of the ball bearing to the stopping push end face of the assembled hole. This invention can increase dependability of engine.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a position limiting device for rotatably supporting an engine crankshaft on an engine body by several crankshaft bearing assemblies. Background technique [0002] The crankshaft of the engine has several rotary journals and several eccentric journals, and a crankshaft bearing assembly is installed at each rotary journal. The crankshaft bearing assembly is actually a detachable sliding bearing, which consists of a It consists of a bearing pad fixed to the engine body and a bearing gland. A set of piston rod is installed at each eccentric journal, and when the piston reciprocates in the cylinder, the piston rod drives the crankshaft to rotate. [0003] The crankshaft of the engine has two ends, one of which is fixed with a flywheel, which is connected with a clutch to output power externally; the other end is fixed with a pulley for internal output power. In a set of crankshaft b...
