Abstract

An apparatus ( 10 ) for connecting a drive assembly ( 4 ) to a bedplate ( 2 ) of an elevator system. The apparatus ( 10 ) includes a first support ( 14 ) for mounting a motor ( 6 ) of the drive assembly ( 4 ) to the bedplate ( 2 ). The apparatus ( 10 ) further includes a second support ( 16 ) for mounting a brake unit ( 8 ) of the drive assembly ( 4 ) to the bedplate ( 2 ). The first support ( 14 ) and the second support ( 16 ) are separate parts.

First claim

What is claimed is:

1. An apparatus ( 10 ) for connecting a drive assembly ( 4 ) to a bedplate ( 2 ) of an elevator system, the apparatus ( 10 ) comprising:
a first support ( 14 ) for mounting a motor ( 6 ) of the drive assembly ( 4 ) to the bedplate ( 2 ); and
a second support ( 16 ) for mounting a brake unit ( 8 ) of the drive assembly ( 4 ) to the bedplate ( 2 );
wherein the first support ( 14 ) and the second support ( 16 ) are separate individual parts;
wherein the first support ( 14 ) is formed from sheet metal; and/or
wherein the second support ( 16 ) is formed from sheet metal; and/or
wherein the intermediate connecting part ( 20 ) is formed from sheet metal;
wherein the drive assembly ( 4 ) further comprises a drive shaft ( 34 ) connected between the motor ( 6 ) and the brake unit ( 8 ); and
wherein the apparatus ( 10 ) further comprises:
at least one bearing stand ( 22 a , 22 b ) configured to support a drive shaft ( 34 ) of the drive assembly ( 4 ), the at least one bearing stand ( 22 a , 22 b ) formed integrally with the first support ( 14 ) and/or the at least one bearing stand ( 22 a , 22 b ) formed integrally with the second support ( 16 ); and
at least one bearing stand support ( 24 a , 24 b ), wherein each bearing stand support ( 24 a , 24 b ) is configured to support the at least one bearing stand ( 22 a , 22 b ) and to connect the at least one bearing stand ( 22 a , 22 b ) to the bedplate ( 2 ).

2. An apparatus ( 10 ) as claimed in claim 1 , further comprising an intermediate connecting part ( 20 );
wherein at least one of the first support ( 14 ) and the second support ( 16 ) is connected to the bedplate ( 2 ) via the intermediate connecting part ( 20 ).

3. An apparatus ( 10 ) as claimed in claim 2 , wherein the intermediate connecting part ( 20 ) extends along at least part of a side of the bedplate ( 2 ).

4. An apparatus ( 10 ) as claimed in claim 2 , wherein the intermediate connecting part ( 20 ) extends along at least part of a bottom surface of the bedplate ( 2 ).

5. An apparatus ( 10 ) as claimed in claim 1 , wherein the drive assembly ( 4 ) further comprises;
at least one drive sheave ( 28 ) mounted on the drive shaft ( 34 ); and
at least one tension member wrapped at least partially around the at least one drive sheave ( 28 );
wherein the apparatus ( 10 ) further comprises a retainer ( 26 ) configured to retain the at least one tension member on the at least one drive sheave ( 28 ).

6. An apparatus ( 10 ) as claimed in claim 5 , wherein the retainer ( 26 ) comprises a substantially horizontal part ( 26 b ) situated above the drive sheave ( 28 ); and
at least one substantially vertical part ( 26 a ) configured to connect the substantially horizontal part ( 26 b ) to the bedplate ( 2 ).

7. An apparatus ( 10 ) as claimed in claim 6 , wherein:
the drive assembly ( 4 ) comprises a plurality of tension members; and
the at least one substantially vertical part ( 26 a ) of the retainer ( 26 ) is configured to prevent the plurality of tension members from coming into contact with one another.

8. An apparatus ( 10 ) as claimed in claim 5 , wherein the retainer ( 26 ) is formed from sheet metal.

9. An apparatus ( 10 ) as claimed in claim 1 , wherein the drive shaft ( 34 ) extends from a face of the motor ( 6 );
wherein the first support ( 14 ) is configured to substantially cover the face of the motor ( 6 ) from which the drive shaft ( 34 ) extends; and
wherein the first support ( 14 ) comprises an aperture for the drive shaft ( 34 ).

10. An apparatus ( 10 ) as claimed in claim 1 , wherein the second support ( 16 ) is configured to substantially cover a face of the brake unit ( 8 ); and
wherein the second support ( 16 ) comprises an aperture to receive the drive shaft ( 34 ).

11. An apparatus ( 10 ) for connecting a drive assembly ( 4 ) to a bedplate ( 2 ) of an elevator system, the apparatus ( 10 ) comprising:
a first support ( 14 ) for mounting a motor ( 6 ) of the drive assembly ( 4 ) to the bedplate ( 2 ); and
a second support ( 16 ) for mounting a brake unit ( 8 ) of the drive assembly ( 4 ) to the bedplate ( 2 );
wherein the first support ( 14 ) and the second support ( 16 ) are separate individual parts;
wherein the drive assembly ( 4 ) further comprises a drive shaft ( 34 ) connected between the motor ( 6 ) and the brake unit ( 8 );
the apparatus ( 10 ) further comprising:
at least one bearing stand ( 22 a , 22 b ) configured to support a drive shaft ( 34 ) of the drive assembly ( 4 );
at least one bearing stand support ( 24 a , 24 b ) configured to support the at least one bearing stand ( 22 a , 22 b ) and to connect the at least one bearing stand ( 22 a , 22 b ) to the bedplate ( 2 );
wherein the at least one bearing stand support ( 24 a , 24 b ) is formed from sheet metal.
