The cross-sectional view shows a cross-section along a shaft axis 61 of the drive shaft 15 of the drive 3 parallel to the longitudinal axis of the guide rail. In FIGS. 1 and 2, the shaft axis 61 of the drive 3 is aligned at least approximately perpendicular to the rotation axis 31 of the rotary joint 9. In particular, the drive system 1 is designed such that the shaft axis 61 runs at least approximately parallel to the drive side wall of the elevator car.

[0032] The drive suspension 7 comprises a revolute joint 9 for tiltably mounting the drive 3 to the support element 5. The revolute joint 9 comprises a fixed part 21 fixed to the support element 5. The revolute joint 9 also comprises a first suspension part 23 fixed to the drive 3.

For example, as shown in Fig. 2, the fixed part 21 extends between the two first openings of the first suspension part 23 and the second opening of the fixed part 21 is arranged between the two first openings of the first suspension part 23. The hinge-like connection between the fixed part and the first suspension part allows for an increased bending stiffness of the rotary joint 9, for example with respect to torques perpendicular to the axis of rotation 31 of the rotary joint 9, in particular with respect to torques in the direction of the longitudinal axis of the guide rail. The connecting means 29 is arranged to pass through the two first and second openings. In figures 1 and 2 the connecting means 29 is designed as a bolt, in particular a threaded bolt, which is guided through the first and second openings and fixed with a nut.

[0033] The drive suspension 7 comprises an adjustment device 11. The adjustment device 11 comprises a fixed part 21 and a second suspension part 41. The second suspension part 41 is linearly displaceable relative to the fixed part 21. In the embodiment of FIG. 2, the second suspension part 41 can be displaced relative to the fixed part 21 by rotating an adjustment screw 43 of the adjustment device 11. By displacing the second suspension part 41 relative to the fixed part 21, the inclination of the drive 3 about the rotation axis 31 of the rotary joint 9 relative to the support element 5 can be set or adjusted. In particular, the inclination of the drive shaft 15 and of the friction drive pulley 13 arranged on the drive shaft 15 relative to the support element 5 can also be set. By setting the inclination of the friction drive pulley 13, for example, in the case of using a belt as the carrier means, skew of the belt can be prevented or reduced.

[0034] 1 and 2 comprises an isolation element 47 arranged between the first suspension part 23 and the fixed part 21 and between the second suspension part 41 and the fixed part 21. In particular, a further isolation element 47 is arranged around the connection means 29 in the region of the first opening of the first suspension part 23 and in the region of the second opening of the fixed part 21. The isolation element 47 is designed to reduce, in particular to damp, the transmission of vibrations or structure-based noise from the drive 3 to the support element 5.

[0035] The drive 3 is designed as a gearless electric motor in Fig. 2. The drive suspension 7 comprises an adapter plate 33 which is fixed to the electric motor.

In FIG. 3, the fixed part 21 comprises a frame structure 40 fixed to the support element and intermediate blocks 39 in each of which the second openings of the fixed part 21 are formed. In particular, the intermediate blocks 39 are able to transfer loads between the connecting element 29 and the frame structure 40. In FIG. 3, the frame structure 40 and the intermediate blocks 39 are rigidly connected to each other, for example by screwing.

[0037] In FIG. 3, the adjusting device 11 comprises a second suspension part 41 which partially surrounds the friction drive pulley 13 of the drive 3. The second suspension part 41 is designed in the form of a cage around the friction drive pulley 41, the cage-shaped second suspension part 41 having a window for the passage of the carrier means. On the side of the second suspension part 41 facing the support element 5, the adjusting device 11 has an adjustment screw for setting the inclination of the drive 3 relative to the support element 5. The isolating element 47 is arranged between the first suspension part 23 and the fixed part 21 and between the second suspension part 41 and the fixed part 21. In the embodiment of FIG. 3, the first suspension part 23, the second suspension part 41 and the adapter plate 33 are formed in one piece. The one-piece design can in particular give the drive suspension a high level of stability.

[0038] Figures 4 and 5 show an embodiment of an elevator installation 51. The elevator installation 51 comprises a drive system 1 according to the embodiments described herein, which comprises a drive 3 and a drive suspension 7 for fixing the drive 3 to a support element 5. In Figures 4 and 5, as support element 5, a guide rail is provided, which guides an elevator car 53. The elevator car 53 is typically connected to a counterweight 55 via a carrier means 57. The carrier means 57, for example a belt, is guided on a friction drive pulley 13 of the drive 3. The drive 3 is designed to drive the carrier means 57 and thus move the elevator car 53 and the counterweight 55 up and down.

[0039] In Figures 4 and 5, the drive 7 is arranged in the upper end region of the elevator installation 51. As shown by way of example in the plan view of the elevator installation 51 in Figure 5, the shaft axis 61 of the drive 3 is aligned at least approximately parallel to the drive side wall 63 of the elevator car 53. The rotation axis 31 of the rotary joint of the drive suspension 7 is oriented at least approximately perpendicular to the shaft axis 61 and at least approximately perpendicular to the vertical direction. The inclination of the shaft axis 61 relative to the up-down direction or relative to the longitudinal axis of the guide rail is set, for example, to be at least approximately perpendicular.

The further drive system 71 comprises a further drive 73 and a further drive suspension 75 for fixing the further drive 73 to a further support element 79, formed by a further guide rail of Figures 4 and 5. The further drive 73 is designed to drive a further carrier means 81 connected to the elevator car 53 and a further counterweight 77. The use of the further drive system can allow the use of a smaller or lighter drive. In particular, the space requirements of the drive in the shaft head or shaft pit can be reduced. Furthermore, a smaller or lighter drive can be installed more easily.

[0041] FIG. 6 shows a method 100 for mounting a drive to a support element of an elevator installation in one embodiment. At 110, the method 100 comprises a step of mounting the drive to the support element via a rotary joint. For example, the fixed part of the drive suspension is fixed to the guide rail at 110, for example by being rigidly screwed. The first suspension part and the second suspension part are fixed to the drive via an adapter plate. The drive is then positioned such that a bolt is guided through at least one first opening of the first suspension part and at least one second opening of the fixed part to form a hinge-like rotary joint. The bolt is fixed with a nut. This method can provide the advantage that the drive can be positioned and mounted on the support element, for example manually.

[0042] After mounting, the drive is stabilized at 120 relative to the support element. In this embodiment, the second suspension is connected to the fixed part so as to constitute an adjustment device, and after connection, the second suspension and the fixed part are settably displaceable relative to each other via an adjustment screw. In particular, after stabilization, the drive can no longer be moved freely about the rotation axis of the rotary joint, but rather can only be moved by rotating the adjustment screw.

[0043] At 130, the tilt of the drive about the revolute joint is set by rotating an adjustment screw. The tilt of the drive or the drive shaft axis is set such that the shaft axis extends at least substantially perpendicular to the up-down direction or such that belt skew is prevented or reduced.
