Abstract
An arrangement in connection with a spreader roll drive where the driving motor is directly connected to the one end of the spreader roll. Bearings support the end of the stationary axle within the drive shaft. The drive shaft is supported by bearings within a spherical ball clamp, which is held by a spherical cavity in a bracket. The drive shaft is connected to a motor or a motor and gearbox arrangement by a flexible coupling.
Claims5
A flexible end supporting arrangement for direct drive of a spreader roll drive, the arrangement comprising:
- a drive means;
- a fixed, arched shaft on which a plurality of flexibly coupled cylindrical roll segments are rotatably supported;
- said cylindrical roll segments including at least one end roll segment;
- a cylindrical drive shaft coupled to at least one end roll segment;
- a stationary member including a spherical internal supporting surface and at least one aperture having a threaded portion;
- a clamping member having a spherical outer surface arranged for mating engagement with said spherical internal supporting surface of said stationary member, and a threaded bracket plug located in said aperture and having a surface engagable with said spherical outer surface of said clamping member to provide rotational resistance of said clamping member with respect to said stationary member;
- and
- a flexible coupling member connecting said drive shaft to said drive means.
