Problems solved by technology

However, due to the narrow space, the gap between the brush ring and the mandrel is very small and difficult to fill. Once there are impurities, the insulation of the wire is damaged, or even the air humidity is high, the insulation performance of the conductive slip ring will be greatly reduced. even conduction, causing the entire device to fail
When the conductive slip ring works in a liquid medium, it is more likely to have problems such as the decline in the insulation performance of the conductive slip ring or the conduction

Embodiment Construction

[0023] see Figure 1~Figure 6 , an insulating mandrel conductive slip ring, including a rotor part and a stator part, brush rings 8 and insulating spacers 10 are alternately installed on the insulating mandrel 7 to form the rotor part of the conductive slip ring. Brushes 9 and brush spacers 11 are alternately installed on the brush fixing rod 15 of the slip ring base 12, and the extension spring 16 between the brushes 9 constitutes the stator part of the conductive slip ring. A bearing 14 is provided between the insulating mandrel 7 and the slip ring base 12, and an end cover 13 is connected to one end of the conductive slip ring, wherein the insulating mandrel 7 is made of insulating material.

[0024] Among them, the shaft body of the insulating mandrel 7 is composed of the front section 1 of the shaft body, the middle section 2 of the shaft body and the rear section 3 of the shaft body. The diameter is greater than the diameter of the middle section 2 of the shaft body. A ...

Abstract

Disclosed is an insulation central spindle electric conduction slip ring. Brush rings and insulation spacers are alternately arranged on a central spindle to form a rotor portion, the main portion of a stator is formed by facts that brushes and brush spacers are alternately arranged on brush fixing rods of a slip ring base and tension springs are disposed among brushes, and the central spindle is made of polyetheretherketone of thermoplastic plastics. According to the insulation central spindle electric conduction slip ring, the problem of insulation between the brush rings and a slip ring spindle, which frequently occurs in existing electric conduction slip rings, is radically solved so that reliability of the electric conduction slip ring is greatly improved, reliability of equipment which is provided with the slip ring is improved, and especially the slip ring has an important significance in precision equipment.

Description

[0001] technical field [0002] The invention relates to a transmission device, in particular to an insulating mandrel conductive slip ring. Background technique [0003] The conductive slip ring is a precision power transmission device used in the relative rotation mechanism. The mandrel in the slip ring is often made of metal materials for torque transmission. However, due to the narrow space, the gap between the brush ring and the mandrel is very small and difficult to fill. Once there are impurities, the insulation of the wire is damaged, or even the air humidity is high, the insulation performance of the conductive slip ring will be greatly reduced. Even conduction, causing the entire device to fail. When the conductive slip ring works in a liquid medium, it is more likely to have the problem of degradation of insulation performance or conduction of this type of conductive slip ring. Contents of the invention [0004] The purpose of the invention is to provide a new...
