Embodiment Construction

[0012] The technical implementation process of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] combine figure 1 As shown, a one-shaped rotating shaft includes a shaft sleeve 1, a nut 2, a cone 3 and a shaft core 4, the cone 3 nests the shaft core 4, and the nut 2 is connected to the shaft core 4 (nested cone 3) At the end of the shaft, the assembly of the shaft core 4, the cone piece 3 and the nut 2 is nested into the shaft sleeve 1 to form a straight shaft.

[0014] Since the shaft sleeve 1 and the shaft core 4 are the two ends that need to rotate with each other, but they can stop at any position when rotating, here just need friction force to achieve self-locking after the external force is removed when rotating. Inside, then load onto taper piece 3, the end of axle core 4 loads onto nut 2, then whole is packed in the axle sleeve 1, forms the complete inline rotating shaft.

Abstract

The invention discloses a linear rotary shaft, which includes a shaft sleeve, a nut, a conical sheet and a shaft core. The conical sheet embeds the shaft core, the nut is connected to the end of one end of the shaft core-embedded conical sheet, and the assembled body of the shaft core, the conical sheet and the nut are embedded into the shaft sleeve to form the linear rotary shaft. By the applicable design of the conical design, the invention solves factors such as non-constant torsion force, etc. due to factors such as difficult control of dimension, etc. while in direct fitting of single shaft sleeve, etc., and also simplifies another kind of spring structure; and the invention converts the interference extent of the shaft hole required to be manufactured into the fitting of conical surfaces, when the shaft core extends more into the conical sheet, since the conical surface effect can enlarge the diameter of the conical sheet to generate the required friction force and torsion force, magnitude of the force can be realized by the locking extent of the nut.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an in-line rotating shaft. Background technique [0002] There are mainly two types of in-line shafts that exist today. One is the direct fit of a simple shaft sleeve, which generates torque through friction to achieve rotational connection. The friction force of this structure is mainly generated by the diameter interference between the shaft and the inner and outer cylindrical surfaces of the sleeve. The manufacturing accuracy requirement is very high, which is not easy to meet during processing, the generated torque is unstable and unreliable, and the scrap rate of parts is high; the other is an inline shaft with an elastic structure, which generates torque through the force of a spring. The spring of this structure is too complicated and difficult to manufacture, so it is rarely produced at present. [0003] Contents of the invention [0004] In order to overcome the deficien...
