Emergency braking mechanism applied to adjusting shaft

Abstract

The invention discloses an emergency braking mechanism applied to an adjusting shaft, and relates to the field of adjusting shafts, the emergency braking mechanism comprises a middle rail and extension mechanisms, folding cavities are symmetrically and fixedly installed on the two sides of the middle rail, the extension mechanisms are symmetrically and rotatably installed at the upper ends and the lower ends of the folding cavities, and each extension mechanism comprises a wing plate, a rotating pin, a sleeve, a ratchet wheel, a shaft rod, a first wrench and a pawl. The problems that a bearing seat serves as a device for externally supporting an adjusting bearing, a bearing seat in the current market is simple in structure and single in function, can only achieve the effect of installing and supporting an adjusting shaft, is deficient in function, generally does not have a braking effect, and needs to wait for stopping the adjusting shaft in the frequent machining process, so that the production cost is high, and the like are solved. The invention provides an emergency braking mechanism applied to an adjusting shaft, which aims at solving the technical problems that the existing adjusting shaft has a certain limitation due to the influence on the machining working efficiency, provides a self-lubricating capability for a bearing seat, prolongs the service life of the bearing seat, and also provides the bearing seat with the functions of adapting to different specifications of adjusting bearing loads and braking.

Description

technical field [0001] The invention relates to the field of adjustment shafts, in particular to an emergency braking mechanism applied to an adjustment shaft. Background technique [0002] As the name suggests, the adjusting shaft is a rotating shaft that can be rotated and has a variable stroke. It is often used in the transmission of power systems and is widely used in all walks of life. The load support of the adjusting shaft is usually completed by the bearing seat. [0003] The common problems of the existing adjusting shaft braking device are: the bearing seat is a device that acts as an external support for the adjusting bearing. The support function is relatively lacking in function, and generally does not have a braking effect. In the frequent processing process, it is necessary to wait for the adjustment axis to stop. To a certain extent, it affects the working efficiency of processing and has certain limitations. SUMMARY OF THE INVENTION [0004] The purpose o...

Problems solved by technology

[0003] The common problems of the existing adjusting shaft braking device are: the bearing housing acts as an external support device for the adjusting bearing. Currently, the bearing housings on the market have a simple structure and a single function, and can only be used to install and adjust the adjusting shaft. The support function is relatively lacking in function, and generally does not have a braking effect. In the frequent processing process, it is necessary to wait for the adjustment shaft to stop. To a certain extent, it affects the working efficiency of the processing and has certain limitations.
