specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 1-Figure 9 Describe this embodiment, the on-orbit maintainable low power consumption high reliability space brake of this embodiment includes a brake housing 1, a connecting shaft system 3 and a first bearing 20, and the brake housing 1 is sleeved on the connecting shaft system 3 A first bearing 20 is arranged between the brake housing 1 and the connecting shaft system 3; the on-rail maintainable space brake with low power consumption and high reliability also includes a double-winding redundant electromagnetic coil 2, an air gap adjustment sleeve 4, Armature friction disc 5, brake gear 6, brake cover 9, manual spring 10, spring gland 11, gear shaft 13, bearing gland 14, second bearing 15, multiple spring guide rods 16, multiple brake springs 17 and a plurality of first fastening nuts 19; an annular groove 1-1 is opened on the friction end surface of the brake housing 1, and the double-winding redundant electromagnetic c...

specific Embodiment approach 2

[0012] Specific implementation mode two: combination Figure 4 and Figure 9 The present embodiment will be described. The diameter of the friction disc boss 5-1 in this embodiment is equal to the diameter of the gear boss 6-1. With such arrangement, the contact area is large, which better guarantees the reliability when the armature friction disc contacts with the large brake gear. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0013] Specific implementation mode three: combination Figure 4 and Figure 9 To describe this embodiment, the end surfaces of the friction disc boss 5-1 and the end surface of the gear boss 6-1 in this embodiment are both coated with a high wear-resistant ceramic coating. In this way, the high wear-resistant ceramic coating has the advantages of good thermal stability, large and stable friction coefficient and small wear. The characteristics of its thermal stability ensure that the brake has small deformation and stable mechanical properties in the vacuum high and low temperature environment of the space. The friction coefficient is large, so that the braking effect of the brake has obvious advantages compared with the brake of general materials. The stable friction coefficient ensures the stability of the braking torque and improves the stability and reliability of the brake in the space environment. The small amount of wear increases the brake's in-orbit service time an...

Abstract

The invention discloses an on track maintainable low-power consumption high-reliability space brake, which relates to a space brake. The invention aims to solve the problems of low reliability, high power consumption and incapability of on track maintenance for the existing space brake. A duplex-winding redundant magnet coil provided by the invention is installed in a circular groove; an air gap adjusting sleeve cylinder is sleeved on a connecting shafting; an armature friction plate is connected with a brake shell through a plurality of spring guide rods and a nut; a brake spring is sleeved on each spring guide rod; a large brake gear is fixedly sleeved on the connecting shafting; the end surface of a friction plate boss is in contact with the end surface of a gear boss; a gear shaft is penetrated on a brake cover; the inner shaft end of the gear shaft is provided with a small gear; a spring pressing cover is positioned at the outer side of the brake cover and is fixedly sleeved on the gear shaft; a manual spring is sleeved on the gear shaft; and when the brake works, the small gear is separated from the large brake gear, and when the brake is maintained, the small gear is meshed with the large brake gear. The on track maintainable low-power consumption high-reliability space brake is used for space service equipment.

Description

technical field [0001] The invention relates to a space brake, in particular to an on-orbit maintainable space brake with low power consumption and high reliability. Background technique [0002] According to the current situation of my country's space technology development, it has become the general trend to design self-developed space equipment. Although some progress has been made in the design of space equipment braking components in China, the core components of space braking components still rely on foreign products and the improvement of general ground equipment. The problem is that they cannot be applied to the requirements of space environments. High power consumption, high quality, low reliability and short life. At present, there are no on-orbit maintainable, high-reliability, low-power, and light-weight brake components specially used for space equipment in China. Space brake components that can realize the above functions have become a key link in my country'...
