Embodiment Construction

[0022] The schematically shown drive device 1 for a rope winch comprises a drive motor 2 which can be designed as an electric motor, a hydraulic motor or a similar drive motor.

[0023] The drive shaft 5 of the drive motor 2 forms the input shaft of the transmission mechanism 3, which at the input speed E ( image 3 ) to drive. The output shaft of the transmission mechanism 3 is formed by the driven shaft 4, which rotates at an output speed A ( image 3 ) to rotate. The driven shaft 4 drives the rope drum 6 of the rope winch in a manner not shown in more detail ( figure 1 with 2 ).

[0024] The transmission 3 has a transmission with a first transmission ratio F between the drive shaft 5 of the drive motor 2 and the output shaft 4 to the rope drum 6 . 1 The first driving connection structure 10 is used as the first gear ( image 3 ).

[0025] in accordance with figure 1 In the embodiment, the first driving connection structure is composed of a first driving wheel 11 , a...

Abstract

The invention relates to a drive device (1) for the spool (6) of a winch. The drive device (1) comprises a drive motor (2) having a drive shaft (5), a transmission (3) and an output shaft (4) that drives a spool (6). The transmission has a first drive connection (10) between the drive shaft (5) of the drive motor (2) and the output shaft (4) to the spool (6). The first drive connection (10) drivesthe output shaft (4) over a first rotational speed range (DB1) in a first gear. According to the invention, a second drive connection (30) is provided between the drive motor (2) and the output shaft(4), wherein the second drive connection (30) drives the output shaft (4) over a second rotational speed range (DB2) in a second gear. The second drive connection (30) is designed to be separate fromthe first drive connection (10) as a parallel drive path, and is driven by the drive motor (2) together with the first drive connection (10). If the output shaft (4) is driven by the second drive connection (30), the power flow of the first drive connection (10) from the drive shaft (5) to the output shaft (4) is interrupted.

Description

technical field [0001] The present invention relates to a driving device for a rope drum (or called a coiled rope drum, namely Seiltrommel) of a rope winch (or called a winch, namely Seilwinde). Background technique [0002] A drive for a rope drum of a rope winch is generally known. The drive device includes a drive motor with a drive shaft, a transmission mechanism and a driven shaft that drives the rope reel. The transmission has a drive connection between the drive shaft of the drive motor and the output shaft to the cable drum. The driven shaft is driven within a preset rotational speed range via the gear ratio. [0003] To pull a load, low rotational speeds at high torques are expedient. Accordingly, the drive connection between the drive shaft of the drive motor and the output shaft of the transmission is designed accordingly. [0004] In order to wind the drawn pulling rope onto the rope drum, a slow, controlled pulling is desired, depending on the pulling condit...
