Abstract

The invention discloses a male and female stepped shaft, a double-shaft mutual-choking hinged connection device and engineering machinery. The male and female stepped shaft comprises a male pin shaft and a female pin shaft; each of the male pin shaft and the female pin shaft is a stepped shaft formed by sequentially connecting a connecting surface, a bearing surface, a limiting surface and a clamping handle, and a through hole penetrating through the stepped shaft is formed in the center of the stepped shaft; when the male pin shaft and the female pin shaft are used in a paired mode, the borne radial force is partially converted into axial force, and mutual choking and interlocking are achieved. The double-shaft conjugating hinged connection device comprises a movable assembly, a spherical hinge assembly, a fastening accessory and a fixed assembly. The fixing assembly comprises a male and female stepped shaft, a penetrating part and a pressing plate part. The male pin shaft and the female pin shaft are inserted from the two sides of an inner ring mounting hole of the spherical hinge assembly in a paired mode, the male pin shaft and the female pin shaft are axially connected through the penetrating part, and the male pin shaft and the female pin shaft are radially pressed and axially limited through the pressing plate part. Compared with an existing traditional hinge connecting device, the fixing mode of the hinge connecting device is more reliable, the dismounting and mounting performance is good, and the hinge connecting device has excellent maintenance convenience.

Description

technical field [0001] The invention relates to a male-female stepped shaft and a double-shaft mutual choke hinge connection device, which belongs to the field of mining machinery. Background technique [0002] Mining dump trucks have a high attendance rate and complex and harsh working conditions. During operation, active components such as suspensions, steering, and lifting cylinders are subjected to compound impact loads in multiple directions, and the frequency of maintenance and replacement is relatively high. In order to ensure reliable connection, the existing hinged connection device mostly adopts the shaft-hole cooperation fixing method that the pin shaft penetrates through a pair of fixed support holes. In this traditional connection method, in order to ensure reliability, the coordination accuracy between the shaft holes is high. And most of them are interference fit, which leads to high manufacturing cost and difficult installation. If the interference is large, ...
