Abstract
In a flat sliding gear drive formed of flat panel-shaped sliding elements (1), (2), with a first sliding element (1) connected to a motor and a second sliding element (2) connected to a variable load, the first and second sliding elements (1), (2) have interacting wedge surfaces which are curved for providing a uniform torque loading of the driving motor.
Claims8
A sliding gear drive, comprising a first sliding element (1) arranged to be connected to a drive motor;
- a second sliding element (2) arranged to be engaged by a variable load and in engagement with said first sliding element by a wedge transmission connection, and said wedge transmission connection being arranged so that the drive motor is acted upon by a torque not proportional to the variable load;
- wherein said first and second sliding elements (12) are formed as flat panel-shaped components, and each of said components has an end surface forming the wedge transmission connection with the end surfaces having a curved form, and
- wherein the first driving sliding element (21) is stepped in a sliding direction, and the stepped end surface is shaped as an additional wedge surface (23), and wherein at least two separately mounted driven second sliding elements (13), (20) are provided.
A sliding gear drive, comprising a first, driving sliding element (1) including means (22) for connecting the first, driving sliding element (1) with a drive motor;
- a second, driven sliding element (2);
- means (18) for applying a variable load to the second, driven sliding element (2);
- and a wedge transmission connection (3,4) for drivingly connecting the first and second sliding elements and for applying to the drive motor a torque not proportional to the variable load applied to the second driven sliding element (2).
