    摘要: Two springs inserted in series, which press a tension roller against a drive belt, are provided in a tension device for a drive belt. The tension spring essentially effects adjustment of the tension roller during assembly and after that effectively is inoperative. The working spring is active during operation and within a limited range of adjustment of the tension roller. The tensions of the two springs are designed so that during assembly equilibrium of forces exists at a middle working point within the path of adjustment. These features result in a simple and precise adjustment during assembly.

    摘要: In a swivel bearing for a braking device the fixed machine part is provided with a flange which has friction surfaces for damping the swivel motion. A flange sleeve made of sheet metal axially and radially surrounds a flange which adjoins the front side of a sleeve section belonging to the swivel arm. The resulting annular space contains, besides the flange, an axially acting spring washer. The flange sleeve itself may optionally have an axial spring action. The flange sleeve is secured axially and against torsion at the sleeve section by means of a turned edge or similar means. The result is a compact arrangement which does not easily disassemble, even in an unmounted condition.

    摘要: A tensioning mechanism for drive belts which consists of a support arm, a rotating tensioning roll mounted on the arm, and a pivot bearing on the support arm a certain distance away from the tensioning roll. The tensioning mechanism is attached together with a mounting plate by a fastener to a machine block. A spring urges the tensioning roll away from the mounting plate and toward the drive belt. In the area of the pivot bearing, the mounting plate has, in the axial direction of the bearing, a fork-shaped cross section with shank sections which support the pivot bearing on both sides, radially and axially, by way of the fastener.

    摘要: In a pre-mounted tensioning device the fastening bolt is covered by the idler wheel. The fastening bolt is serviced through a recess provided in the wheel surface. A pre-mounted unit is created through the insertion of a fastening bolt whose head is pushed by spring elements against the wheel surface, thus preventing the idler wheel from turning and forcing the recess to coincide with the fastening bolt.

    摘要: A tension roller for enabling adjustment of the tightness of a driving belt, comprising a solid support and a bearing press-fit thereon. The solid support has an axially extending mounting bore eccentrically arranged therein and a seating surface formed circumferentially thereon. A plurality of balanced bores are circumferentially distributed in the support in order to obtain a uniform radial elasticity at the seating surface. The balance bores may have a diameter equal to or less than the diameter of the mounting bore. In the latter case, the shortest distance between the balance bore surfaces and the seating surface is equal to the shortest distance between the mounting bore surface and the seating surface. The resultant uniformity of the radial elasticity prevents deformation of the bearing.

    摘要: A tension-adjusting device for a driving belt comprising a tension roller and having an engagement arrangement provided between a support of the tension roller and a machine frame for enabling stepwise swiveling movement about a partially disengaged mounting bolt. The axis of swivel is radially displaced from the rolling axis of the tension roller. The engagement arrangement comprises a projection formed on the support radially displaced from the axis of swivel and a plurality of depressions formed in the machine frame and arranged at regular intervals along an arc defined by the path of travel of the projection during swiveling, whereby the projection is engageable with each depression, thereby defining a corresponding step in a range of adjustment of the tension of the driving belt.
