Problems solved by technology

However, shaft lock nuts require sufficiently long threads for good engagement and set screw elements to prevent the threads from slipping, making them typically bulky and heavy.
A collar may be simpler, but may result in uneven force distribution on the shaft

Embodiment Construction

[0015] The present invention will now be described in detail with reference to the accompanying drawings and examples. The described embodiments are illustrative only, representing only a subset of the embodiments of the invention. Based on the embodiments of the present invention, those skilled in the art can conceive of other embodiments without making creative efforts, and all these embodiments fall within the protection scope of the present invention.

[0016] figure 1 and 2 An exemplary shaft fixation device 100 is shown in accordance with an embodiment of the invention. The fixing device 100 can be used to fix the shaft 200 to a mounting part 300 (eg, a housing or a bearing). Fixture device 100 may include an inner ring 110 and an outer ring 120 .

[0017] The inner ring 110 may have an outer tapered surface 111, such as figure 2 shown. The inner ring 110 may fit over the shaft 200 . When the fixing device 100 is in the unlocked state, the inner diameter of the i...

Abstract

A fixing apparatus (100) for fixing a shaft (200) to a mounting part (300) and an actuator (400) of a robot are provided. The fixing apparatus (100) includes an inner ring (110) and an outer ring (120). The inner ring (110) has an outer tapered surface and is arranged to be sleeved on the shaft (200). The outer ring (120) has an inner tapered surface that fits the outer tapered surface of the inner ring (110). The inner ring (110) and the outer ring (120) are both arranged to abut the mounting part (300) in an axial direction of the shaft (200). The outer ring (120) is configured to be detachably fixed to the mounting part (300), and the inner ring (110) is squeezed by the outer ring (120) to grip the shaft (200) in a radial direction when the outer ring (120) is fixed to the mounting part(300).

Description

[0001] Cross References to Related Applications [0002] This application is filed under 35 U.S.C. § 119(e) of the U.S. Provisional Application No. 62 / 721,322 filed August 22, 2018, entitled "Secure and Releasable Shaft Anchor with High Compactness" priority of the patent application, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates generally to a shaft holder structure, and in particular to a fixing device for fixing a shaft to a mounting part and a drive for a robot. Background technique [0004] Shaft locking retainers are widely used to secure components to shafts and prevent them from being moved by axial forces or moments. Common solutions include shaft lock nuts and collars. However, shaft lock nuts require sufficiently long threads for good engagement and a set screw element to prevent the threads from slipping, thus making them generally bulky and heavy. A collar may be simpler, b...
