Abstract

The invention relates to a transmission belt deviation rectifying device and an elevator. The transmission belt deviation rectifying device comprises: a base (6); rolling wheels (1) comprising a first rolling wheel (1a) and a second rolling wheel (1b) which are installed on the base (6) and arranged side by side at intervals in the first direction, wherein the first rolling wheel (1a) and the second rolling wheel (1b) are connected and can synchronously move relative to the base (6) in the first direction, and the first direction is perpendicular to the axial direction of the rolling wheels (1); and a reset mechanism (4) comprising a first reset elastic component connected with the first rolling wheel (1a) and the base (6) and a second reset elastic component connected with the second rolling wheel (1b) and the base (6), wherein the first reset elastic component and the second reset elastic component drive the rolling wheel (1) in opposite directions respectively to make reset elastic force for driving the rolling wheels (1) to the preset position in the first direction applied to the rolling wheels (1). The transmission belt deviation rectifying device is changed into a dynamic flexible deviation rectifying mode from a hard deviation rectifying mode in the prior art, and the influence of deviation rectifying on belt transmission vibration is reduced.

Description

technical field [0001] The invention relates to the technical field of belt transmission, in particular to a belt deviation correcting device. Background technique [0002] In the existing hoist transmission, when the transmission belt is used for long-distance transmission, the transmission belt will vibrate, causing the belt to swing. At present, the deviation correction of the belt transmission mostly uses fixed-pitch rollers to limit the range of belt deviation. [0003] In the lifting transmission of the hoist, the deviation correction device of the transmission belt usually includes a fixed roller structure fixed on both sides of the transmission belt, and the distance between the rollers is fixed and cannot be adjusted. When the belt deviates, the rollers will directly block the edge of the belt. This correction method will increase the vibration of the belt drive and affect the stability of the drive. In the synchronous belt drive, it will also increase the possibili...
