Problems solved by technology

However, with the current production process, only one spiral groove can be guaranteed to be embedded in the flexible shaft during the processing process. Once two spiral grooves are reserved, it is easy to cause loose threads during the use of the flexible shaft.

Embodiment Construction

[0027] The invention provides a double-pile flexible shaft and a processing method thereof, and the specific scheme is as follows.

[0028] Such as figure 1 As shown, a double-pile flexible shaft is suitable for some environments that are very sensitive to friction and noise, such as electric seats of luxury cars, etc., and is formed by winding the shaft core and the outer layer of the flexible shaft, and the outer layer of the flexible shaft It includes a plurality of outer layer steel wires 1 and two woolen yarns 2, the plurality of outer layer steel wires 1 and the two woolen yarns 2 are arranged side by side and spirally wound together on the outer peripheral side of the shaft core.

[0029] The shaft core is formed by winding a central steel wire 3 and the inner layer of a multi-layer flexible shaft. The coils are stacked in sequence, spirally wound on the outer peripheral side of the central steel wire 3 , and the winding directions of the inner layers of the flexible s...

Abstract

The invention discloses a double-wool flexible shaft and a processing method thereof. The whole flexible shaft is formed by winding a shaft core and a flexible shaft outer layer, the flexible shaft outer layer comprises a plurality of outer layer steel wires and two pieces of wool, and the plurality of outer layer steel wires and the two pieces of wool are arranged side by side and are jointly and spirally wound on the peripheral side of the shaft core. On the premise that normal use of the flexible shaft is guaranteed, the technical effects of double spiral grooves in the peripheral side of the flexible shaft and embedding of double wool are achieved, friction between the flexible shaft and the inner wall of a pipeline on the periphery of the flexible shaft during high-speed rotation is remarkably relieved, noise is eliminated, and the service life of the whole flexible shaft is prolonged to the maximum extent.

Description

technical field [0001] The invention relates to a flexible shaft and a corresponding processing method thereof, in particular to a double-pile flexible shaft and a processing method thereof, and belongs to the technical field of flexible shaft processing. Background technique [0002] The flexible shaft is a shaft with little rigidity, elasticity, and free bending transmission. It is mainly used to connect two shafts that are not on the same axis and in the same direction or have relative motion to transmit rotational motion and torque. In the field of automobiles or other mechanical equipment, flexible shafts are often used to transmit torque and to flexibly transmit rotary motion to any position. [0003] In order to ensure the safety of personnel during the rotation of the flexible shaft, the flexible shaft is usually installed in a relatively closed pipe to rotate during the application of the flexible shaft. Friction occurs on the inner wall of the pipe, resulting in l...
