The structure limits the gap compensation sheet on the inner wall of the flat key groove through the mounting screw, and keeps a gap between the head of the mounting screw and the gap compensation sheet to provide an arched space for the gap compensation sheet.
Further, in the crankshaft of the snow sweeper, the clearance compensation piece is a metal elastic piece.
Further, in the snowplow bent axle, the clearance compensation pieces on the two side walls of the flat key groove are symmetrically arranged.
Further, snowplow bent axle in, adjusting screw's outer end does not expose the outer terminal surface of first hole section, can not influence the installation of main journal outside subassembly.
The utility model has the advantages that:
the utility model has the advantages of simple structure, and reasonable design has the wearing and tearing clearance compensation function, through having add adjustable clearance compensation piece on flat keyway inner wall, after because wearing and tearing and clearance grow between the contact surface of flat key and flat keyway, through adjusting screw change effect on the clearance compensation piece support pressure and make clearance compensation piece can arch up and support the tight contact with the flat key to flat keyway, the compensation wearing and tearing are adjusted simply, can compensate the friction clearance between the two in a flexible way, bent axle moving reliability has been guaranteed, whole life has been prolonged.

Detailed Description
The present invention will now be further described with reference to the accompanying drawings:
referring to fig. 1 and 2, the crankshaft of the snow sweeper comprises a main journal 1, a connecting rod journal 2 and a crank arm 3 connected between the main journal and the connecting rod journal, wherein a flat key groove 4 is concavely arranged on the main journal 1. The inner walls of the two sides of the flat key groove 4 are respectively provided with an adjusting hole, and the central axis of each adjusting hole is perpendicular to the plane of the inner side wall of the flat key groove 4 and penetrates to the outer peripheral wall of the main journal 1; and the inner walls of the two sides of the flat key groove 4 are respectively provided with a clearance compensation sheet 5, and the clearance compensation sheets 5 on the two side walls of the flat key groove 4 are symmetrically arranged. Specifically, the clearance compensation sheet 5 is a metal elastic sheet, and the clearance compensation sheet 5 covers the adjusting hole.
With reference to fig. 2 and 3, the adjusting hole is a stepped hole and includes a first hole section 6 and a second hole section 7, the hole diameter of which is increased from outside to inside, an adjusting screw 8 is connected to the first hole section 6 through an internal thread, and the outer end of the adjusting screw 8 is not exposed out of the outer end surface of the first hole section 6. The inner end of the adjusting screw 8 extends into the second hole section 7 and is pressed against a pressing plate 9, the pressing plate 9 slides along the axial direction of the second hole section 7 and is connected with a pressing spring 10, and the inner end of the pressing spring 10 presses against the clearance compensation sheet 5 to enable the clearance compensation sheet 5 to arch towards the inside of the flat key groove 4.
