Abstract
The utility model discloses a kind of retarder steel-belt type braking device used for oil-field oil pumper, comprise a brake band, described brake band is integrated type, its inside is provided with brake wheel and brake strap successively, brake band and brake strap by rivet riveting and together with, brake strap employing resin rubber non-asbestos friction plate.The beneficial effects of the utility model are, Novel steel band brake is owing to adopting monolithic construction and having certain amount of deformation, brake strap adopts resin rubber non-asbestos friction plate, brake strap and brake wheel in braking state time its area of contact can reach 90 more than ﹪, better can realize the effect of braking, can also reduce the labor intensity of operator in addition, weight itself is also lighter than watt formula braking device of stopping many, brings great convenience to installation personnel.
Description
Technical field
The utility model relates to a kind of retarder steel-belt type braking device used for oil-field oil pumper, belongs to speed reducer apparatus field.
Background technique
Retarder braking device used for oil-field oil pumper generally adopts watt effect realizing braking of stopping, but brake strap and brake wheel its area of contact when braking state is not a lot, and area of contact during its braking can reach 70 ﹪ just can be good at last.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of retarder steel-belt type braking device used for oil-field oil pumper, and structure is simple, good braking effect.
To achieve these goals, the technical solution adopted in the utility model is: a kind of retarder steel-belt type braking device used for oil-field oil pumper, comprise a brake band, described brake band is integrated type, its inside is provided with brake wheel and brake strap successively, brake band and brake strap by rivet riveting with together with.
The thickness of described brake band is 10mm.
Described brake band is Ω type.
Described brake strap adopts resin rubber non-asbestos friction plate.
The beneficial effects of the utility model are, Novel steel band brake is owing to adopting monolithic construction and having certain amount of deformation, brake strap adopts resin rubber non-asbestos friction plate, brake strap and brake wheel in braking state time its area of contact can reach 90 more than ﹪, better can realize the effect of braking, can also reduce the labor intensity of operator in addition, weight itself is also lighter than watt formula braking device of stopping many, brings great convenience to installation personnel.
Accompanying drawing explanation
Fig. 1 is conventional oil field retarder braking device used for oil extractor schematic diagram.
Fig. 2 is structural representation of the present utility model.
In figure: 1, brake band, 2, brake wheel, 3, rivet, 4, brake strap.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of retarder steel-belt type braking device used for oil-field oil pumper, comprise a brake band 1, described brake band 1 is integrated type, and brake band 1 global shape is Ω type, its inside is provided with brake wheel 2 and brake strap 4 successively, brake band 1 and brake strap 4 by rivet 3 riveting with together with.
The thickness of described brake band 1 is 10mm.
Described brake strap 4 adopts resin rubber non-asbestos friction plate.
Novel steel band brake is owing to adopting all-in-one-piece structure and having certain amount of deformation, brake strap and brake wheel in braking state time its area of contact can reach 90 more than ﹪, better can realize the effect of braking, the labor intensity of operator can also be reduced in addition, weight itself is also lighter than watt formula braking device of stopping many, brings great convenience to installation personnel.
