Compact precision angle measurement shafting

Abstract

A compact precision angle measurement shafting comprises a rotary transformer stator seat, a rotary transformer stator pressing plate, a rotary transformer stator, a rotary transformer rotor, a bearing seat, an angular contact bearing pair, a wire cover plate A, a rotating shaft, a bearing end cover and a wire cover plate B, wherein the rotary transformer stator, the rotary transformer stator seat, the rotary transformer stator pressing plate, the rotating shaft and the angular contact bearing pair are connected with the inner ring to form a static part of the precise angle measurement shafting; the outer ring of the angular contact bearing pair, the bearing seat, the bearing end cover and the rotary transformer rotor are connected with one another to form a rotating part of the precise angle measuring shafting; and the wire cover plate A and the wire cover plate B cover the wire in the wiring groove, so that the fixing and protecting effects are achieved. The precise angle measurementshafting has the characteristics of high precision, compact structure, light weight, high strength and rigidity, impact vibration resistance and the like, can adapt to related requirements of missile-borne equipment, can be subjected to modular production, and is beneficial to shortening the equipment development period and reducing the development cost.

Description

technical field [0001] The invention relates to a precision angle-measuring shaft system, in particular to a compact precision angle-measuring shaft system applied to a bomb-loaded three-auto-inertial group dual-axis indexing mechanism. Background technique [0002] As the core component in the development process of the three-self-inertia dual-axis indexing mechanism, the angle-measuring shaft system provides angle measurement and feedback for the realization of the "three-self" functions (self-testing, self-calibration, and self-calibration), and the angle-measuring accuracy directly affects The various precision indexes of the whole equipment play a key role in the development process of the three-automatic inertial group dual-axis indexing mechanism. [0003] The bomb-loaded use environment imposes strict requirements on the size and weight of the three-automatic inertial group dual-axis indexing mechanism. The angle measuring shaft system in the existing products is lar...

Problems solved by technology

[0003] The bomb-loaded use environment imposes strict requirements on the size and weight of the three-automatic inertial group dual-axis indexing mechanism. The angle measuring shaft system in the existing products is large in size, heavy in weight and complex in structure. Therefore, the materials and structure of the existing drive shaft system must be carefully considered The form is modified to meet the above requirements
