Flexible shaft transmission structure

Abstract

The invention discloses a flexible shaft transmission structure which is used for transmitting driving force on a first moving part to a second moving part, a driving shaft is arranged on the first moving part, and a driven shaft is arranged on the second moving part. The flexible shaft transmission structure comprises a flexible shaft body, the two ends of the flexible shaft body are sleeved with a first connecting piece and a second connecting piece respectively, the first connecting piece is detachably connected with the first moving piece, and the second connecting piece is detachably connected with the second moving piece. The flexible shaft body comprises a shaft core and a protective sleeve, the shaft core penetrates through the two ends of the protective sleeve, the two ends of the protective sleeve are sleeved with the first connecting piece and the second connecting piece respectively, the two ends of the protective sleeve are movably connected with the first connecting piece and the second connecting piece in a limiting mode respectively, one end of the shaft core is detachably connected with the driving shaft, and the other end of the shaft core is detachably connected with the driven shaft. The flexible shaft transmission structure is convenient to disassemble, and the after-sales maintenance efficiency of products is improved; and all the parts are independent from one another, so that assembly and stock preparation are facilitated.

Description

technical field [0001] The invention relates to the field of mechanical transmission, more specifically, to a flexible shaft transmission structure. Background technique [0002] The flexible shaft is a shaft with little rigidity, elasticity and free bending transmission; it is used to connect two shafts with different axes and not in the same direction or with relative motion to transmit rotational motion and torque. It can flexibly transmit rotary motion and torque to any position. [0003] Flexible shafts are widely used in mechanical transmission as a flexible transmission system. It can simplify the transmission machinery, the transmission chain is simple, and the transmission direction can be changed and many other advantages, so it is widely used. Such as pneumatic picks, marine water pumps, medical equipment, automobile odometer systems and other fields. [0004] However, due to the high-frequency dynamic change of direction and the high-speed operation of the fle...

Problems solved by technology

[0005]At present, the traditional flexible shaft scheme is a structure in which one end is fixed on the motor coupling; when the flexible shaft needs to be replaced, the machine must be disassembled, which not only It increases the difficulty of after-sales service, and may cause irreversible damage to the product, greatly increasing the cost of manpower and material resources for after-sales maintenance of the product
