Abstract
The invention discloses a frictional component. The frictional component comprises a moving plate (1), and an aluminum cushion plate (2) is arranged on the moving plate (1); a bonding layer is arranged between the aluminum cushion plate (2) and the moving plate (1); both sides of the aluminum cushion plate (2) are provided with through holes, and a blind hole corresponding to the through holes is arranged on the moving plate (1); an elastic cylindrical pin (5) is arranged in the through hole; one end of the elastic cylindrical pin (5) is located in the blind hole of the moving plate (1); the upper part of the through hole is further provided with a pressing plate (6); a screw fixed with the moving plate (1) after orderly crossing through the pressing plate and the aluminum cushion plate (2) is arranged on the pressing plate (6). The frictional component is more stable in structure and longer in service life; therefore, the effectiveness of a brake can be guaranteed better.
Description
Technical field
the present invention relates to a kind of friction component, particularly a kind of friction component for traction machine brake.
Background technology
along with the development of modernization, the use of elevator in people's daily life is more and more frequent.And as the core drive parts of elevator, the demand of towing machine is also increasing.And the brake performance of towing machine directly has influence on the safety of elevator.
and each parts of the friction component of existing drg are all adopt screw to be fixed simply usually, but this fixed form easily occurs loosening inconsistent phenomenon after drg long-time running, thus result in misfunctioning of brake, and then easily causes safety misadventure.
Summary of the invention
the object of the invention is to, a kind of friction component is provided.Its structure is more firm, longer service life, therefore can ensure the validity of drg better.
technical scheme of the present invention: friction component, is characterized in: comprise dynamic plate, and dynamic plate is provided with aluminium backing plate, is provided with tack coat between aluminium backing plate and dynamic plate; Through hole is also established in described aluminium backing plate both sides, and dynamic plate is provided with the blind hole corresponding with through hole, is provided with elastic cylindrical pin in described through hole; Wherein one end of described elastic cylindrical pin is positioned at the blind hole of dynamic plate; Also be provided with pressing plate above described through hole, described pressing plate is provided with successively through the screw fixed with dynamic plate after pressing plate and aluminium backing plate.
in above-mentioned friction component, described aluminium backing plate is bonded with friction lining, described friction lining also by screw and aluminium backing plate fastening.
compared with prior art, the present invention use elastic cylindrical pin coordinate pressing plate mode with, can provide enough moment for aluminium backing plate on dynamic plate, therefore when drg action, friction component can bear larger moment of torsion.And structure of the present invention, it is convenient not only to install, and structural stability is high, has longer service life, fully can ensure the validity of drg.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention;
fig. 2 is schematic cross-section of the present invention.
being labeled as in accompanying drawing: 1-moves plate, 2-aluminium backing plate, 3-friction lining, 5-elastic cylindrical pin, 6-pressing plate.
Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
embodiment.A kind of friction component, as depicted in figs. 1 and 2: comprise dynamic plate 1, dynamic plate 1 is provided with aluminium backing plate 2, is provided with tack coat between aluminium backing plate 2 and dynamic plate 1; Through hole is also established in described aluminium backing plate 2 both sides, and dynamic plate 1 is provided with the blind hole corresponding with through hole, is provided with elastic cylindrical pin 5 in described through hole; Wherein one end of described elastic cylindrical pin 5 is positioned at the blind hole of dynamic plate 1; Also be provided with pressing plate 6 above described through hole, described pressing plate 6 is provided with successively through the screw fixed with dynamic plate 1 after pressing plate and aluminium backing plate 2.Now, pressing plate 6 and aluminium backing plate 2 have been fixed on dynamic plate 1 by screw, but also limit the movement of elastic cylindrical pin 5, play the effect preventing it from coming off.Described aluminium backing plate 2 is bonded with friction lining 3, described friction lining 3 also by screw and aluminium backing plate 2 fastening.
Claims (2)
1. a friction component, is characterized in that: comprise dynamic plate (1), and dynamic plate (1) is provided with aluminium backing plate (2), is provided with tack coat between aluminium backing plate (2) and dynamic plate (1); Through hole is also established in described aluminium backing plate (2) both sides, and dynamic plate (1) is provided with the blind hole corresponding with through hole, is provided with elastic cylindrical pin (5) in described through hole; Wherein one end of described elastic cylindrical pin (5) is positioned at the blind hole of dynamic plate (1); Also be provided with pressing plate (6) above described through hole, described pressing plate (6) is provided with successively through the screw that pressing plate and aluminium backing plate (2) are fixed with dynamic plate (1) afterwards.
2. friction component according to claim 1, is characterized in that: described aluminium backing plate (2) is bonded with friction lining (3), described friction lining (3) also by screw and aluminium backing plate (2) fastening.
