Abstract

The present invention relates to a motorized pulley (1) with a cylindrical cable connector (10) comprising a cylindrical drum (5) that is mounted rotatably about a shaft (11) and is configured for being fixedly mounted on supporting means, said cylindrical drum (5) delimiting an interior space intended for receiving an electric motor (20) for producing a rotating movement of the drum about the shaft (11), and wherein said shaft comprises a cylindrical recess (9) configured at an end of the shaft (11) for receiving the cylindrical cable connector (10) that is electrically coupled to said electric motor (20). Hereby a motorized pulley is accomplished that has a cable connector able to allow for tolerances deriving from the manufacture of the individual parts and mounting tolerances in the motorized pulley with the cable connector.

Claims

1. A motorized pulley with a cable connector (10) comprising a cylindrical drum (5) that is rotatably mounted about a shaft (11) configured for being fixedly mounted on support means, said cylindrical drum (5) delimiting an interior space intended for receiving an electric motor (20) for producing a rotating movement of the drum about the shaft (11), wherein said shaft comprises a cylindrical recess (9) configured at an end of the shaft (11) for receiving the cylindrical cable connector (10) that is electrically coupled to said electric motor (20) and wherein the cable connector (10) comprises a coupling end (48) and a cable end (49), characterised in that said cable connector (10) comprises at that cable end (49) a jacket of a resiliently elastic material and at least one annular, elastic bead (42) that extends continuously radially from the cylindrical surface of the cable connector (10) and abuts on an inner face of the recess (9), and in that said continuously annular bead (42) is configured in the resiliently elastic jacket (44), preferably cast integrally in the resiliently elastic jacket (44).

2. A motorized pulley according to claim 1, characterised in that the cable connector is cylindrical and said jacket (44) encloses the cable connector (10) at the cable end (49) and extends towards the coupling end (48).

3. A motorized pulley (1) according to claim 2, characterised in that the jacket (44) comprises an annular lip sealing (41) that extends from the cable end (49) in a direction away from the cable end (49).

4. A motorized pulley (1) according to claim 3, characterised in that the continuous annular beads (42) have a diameter larger than the cylindrical recess (9) configured at an end of the shaft (11), whereby the continuous annular beads (42) are compressed upon insertion of the cable connector into the recess (9) at the end of the shaft (11).

5. A motorized pulley (1) according to claim 4, characterised in that the cable connector (10) is a male connector.

6. A motorized pulley (1) according to claim 5, characterised in that the cable connector (10) is situated entirely within the recess (9) at the end of the shaft (11).

7. A motorized pulley (1) according to claim 1, characterised in that the jacket (44) comprises an annular lip sealing (41) that extends from the cable end (49) in a direction away from the cable end (49).

8. A motorized pulley (1) according to claim 7, characterised in that the continuous annular beads (42) have a diameter larger than the cylindrical recess (9) configured at an end of the shaft (11), whereby the continuous annular beads (42) are compressed upon insertion of the cable connector into the recess (9) at the end of the shaft (11).

9. A motorized pulley (1) according to claim 8, characterised in that the cable connector (10) is a male connector.

10. A motorized pulley (1) according to claim 9, characterised in that the cable connector (10) is situated entirely within the recess (9) at the end of the shaft (11).

11. A motorized pulley (1) according to claim 1, characterised in that the continuous annular beads (42) have a diameter larger than the cylindrical recess (9) configured at an end of the shaft (11), whereby the continuous annular beads (42) are compressed upon insertion of the cable connector into the recess (9) at the end of the shaft (11).

12. A motorized pulley (1) according to claim 11, characterised in that the cable connector (10) is a male connector.

13. A motorized pulley (1) according claim 12, characterised in that the cable connector (10) is situated entirely within the recess (9) at the end of the shaft (11).

14. A motorized pulley (1) according to claim 1, characterised in that the cable connector (10) is a male connector.

15. A motorized pulley (1) according claim 14, characterised in that the cable connector (10) is situated entirely within the recess (9) at the end of the shaft (11).

16. A motorized pulley (1) according to claim 1, characterised in that the cable connector (10) is situated entirely within the recess (9) at the end of the shaft (11).
