Definitions
- the invention relates to a drive unit for a hoist, in particular for an elevator, according to the preamble of claim 1.
- the drive shaft which is guided through the brake housing consists of three parts which are connected to one another by two couplings.
- One of the clutches is formed by a brake disc carrier on which a brake disc is integrally formed.
- the tripartite shaft with the two shaft couplings, one of which is also provided with a length compensation increase the overall length of the drive unit, increase the mass of the rotating parts and promote the occurrence of vibrations.
- the invention has for its object to design a drive unit of the type mentioned in such a way that it has a short overall length with a simple construction and generates low inertia forces.
- the motor shaft and the transmission shaft are formed by a one-piece, continuous shaft and the brake body is fixed on the shaft within the brake housing, the total length of the drive unit can be significantly shortened, which is a major advantage in the generally cramped installation conditions for elevator drives. In addition, the construction and assembly costs are reduced.
- the motor and the transmission are preferably cantilevered to the brake housing on both sides. They thus form a structural unit that can be preassembled and no longer requires alignment work when installing the hoist, but must be fixed as the only component on the foundation. Depending on the design of the gear unit, it can also be flanged to the brake housing on the output side and connected to the motor on the drive side.
- the brake can be designed as a drum or disc brake or, if necessary, can also be constructed according to other construction principles.
- the parts absorbing the braking forces are fixed either on the brake housing or on a separate carrier.
- the brake body for example the brake drum or brake disc, is preferably attached to the through shaft by means of a flange or a conical coupling, so that partial or complete replacement is possible without undue effort. Accessibility is further improved in that the brake housing has openings through which the brake is accessible.
- a planetary gear is used as the gear, it is advantageously flanged to the side of the brake housing facing away from the motor.
- the outer jacket of the planetary gear can then be designed as a rope pulley projecting into the elevator shaft for the ropes of an elevator, which results in a further saving in overall length.
- the type of flange mounting of the gearbox according to the invention advantageously also enables the use of other types of gear such as e.g. Helical gear, backlash-free precision gear and combination gear.
- a space-saving version of a pulse generator can be mounted on the drive shaft, which can be used for controlled drives. This pulse generator can be integrated into the space of the motor housing or can be formed by the motor drive shaft bearing.
- Fig. 1 shows schematically a drive unit for an elevator with the basic components gear 1, brake 2 and motor 3, which are arranged coaxially.
- the gear 1 is a planetary gear trained and carries on its outer jacket a traction sheave, not shown, for the ropes of an elevator.
- a brake housing 8 with a brake housing is designated, which is integrally connected to a rigid base plate 11.
- the base plate 11 continues until under the motor 3 and is anchored on a foundation, not shown.
- the fixed part of the planetary gear 1 is flanged to the left side of the brake housing 8 in FIG. 1.
- the housing of the motor 3 is attached to the right side of the brake housing 8.
- the rotor 5 of the motor 3, the brake body of the brake 2 and the input part of the planetary gear 1 sit on a common shaft 6 which runs as a continuous shaft through the entire drive unit.
- a handwheel 7 for emergency operation can be placed on the free end of the shaft 6 on the motor side.
- a pulse generator 13 is mounted on the free end of the shaft 6, which is supported on the inside of the motor housing cover.
- the brake body which is designed as a drum or disk, is fixed on the shaft 6 by means of a known conical connection, as is shown schematically in FIGS. 4a and 4b.
- the free end of the shaft 6 can be received in a support bearing 14, which can itself be designed as a pulse generator.
- the support bearing or the free end of the shaft can be covered by a removable cap 15. This cap can be provided with a safety contact in order to ensure that the drive unit cannot be actuated when the handwheel is attached.
- FIGS. 1 and 2 show a drum brake, also with levers 9 and a cylinder 10.
- the lever 9 absorbing the braking force is fixed on the brake housing 8.
- they can also be mounted on the foundation independently of the brake housing 8, so that the braking forces absorbed from the moving masses are not derived via the brake housing 8. In this case it is possible to assemble and install the brake unit on its own carrier as a complete unit.
- a gear with a different, known design can also be used. It is also possible to flange a structural unit designed as a geared motor to one side of the brake housing and to suspend a sheave for the supporting cables on the end of the shaft 6 projecting on the other side.
- the main advantages of the drive unit according to the invention are the significantly shortened design due to the omission of the coupling and the arrangement of a continuous shaft with the bearing of the brake on the shaft in the vicinity of the gearbox or cable pulley bearing, as a result of which the centrifugal masses are reduced and better absorbed can and what the engine support bearing provided in the usual designs can be omitted.
- the brake housing can have lateral openings through which the brake can be monitored and accessed, so that wear can be observed and an easy replacement of brake parts is possible.
