Abstract

The invention relates to a worm gear deviation correcting device, and relates to a deviation adjusting device. The device comprises a machine frame, wherein a support roller assembly is mounted on themachine frame, a conveying belt is supported on the support roller assembly, a transmission rod is arranged on one side of the support roller assembly, a screw rod segment is arranged in the middle of the transmission rod, a screw rod nut is in threaded connection with the screw rod segment, a support swing rod is connected between the screw rod nut and the support roller assembly, one end of thesupport swing rod is rotatably connected with the screw rod nut, and the other end of the support swing rod is fixedly connected with the middle of a support roller support; a vertically-arranged vertical stop roller is rotatably arranged on each of the two sides of the conveying belt, and a gap is reserved between each vertical stop roller and the part, on the corresponding side, of the conveying belt; and the lower end of each vertical stop roller is connected with a transmission shaft, and the lower end of the transmission shaft is in transmission connection with the transmission rod. According to the device, the edge friction of the conveying belt is utilized to drive the vertical stop rollers to rotate to generate torque, and the torque is utilized to be converted through a screw rodfor driving the support roller support to deviate, so that deviation correcting of the conveying belt is achieved, the overall performance is stable, the motion is stable, and the deviation adjustingeffect is obvious.

Description

technical field

[0001] The invention relates to a deviation adjuster, in particular to a deviation correcting device for a worm gear. Background technique

[0002] Conveyor belt conveyor is a kind of material transportation equipment. There are driving rollers and reversing rollers at both ends of the endless conveyor belt. There are multiple idler groups under the conveyor belt to support the conveyor belt. When working, the material is placed on the conveyor belt. The rotation of the driving drum drives the conveyor belt to make directional movement, so as to transport the material to the desired location.

[0003] Because the conveyor belt is running under load, it often happens that the conveyor belt deviates due to uneven force, incorrect center point, and incorrect blanking point. The current method of correcting deviation: ① Weld a set of force arm rods at both ends of the bracket of the self-aligning idler group, and fix the vertical retaining roller on the force ar...
