摘要： A worm gear has a threaded spindle and a threaded nut, the thread on the spindle or the nut or on both having a profile such that the transition regions connecting the thread crown surface to the thread flanks are rounded, as is the crown surface itself. Further, the spindle thread and nut thread are intermeshed with axial and radial play such that radial forces exerted under torque loading are transmitted only by areas of the crown surface, which transmitted forces are supported by the respective areas of the opposing groove bottom. Smooth functioning is ensured even when the threaded spindle occupies a position of maximum inclination relative to the nut.
摘要翻译： 蜗轮具有螺纹主轴和螺纹螺母，主轴或螺母上的螺纹或两者具有轮廓，使得将螺纹牙冠表面与螺纹侧面连接的过渡区域如冠表面本身一样是圆形的。 此外，主轴螺纹和螺母螺纹与轴向和径向游隙相互啮合，使得在扭矩加载下施加的径向力仅由冠表面的区域传递，该传递力由相对的凹槽底部的相应区域支撑。 即使当螺纹主轴相对于螺母处于最大倾角的位置时，也能确保平滑的功能。

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 bearing on a shaft is separated from the bore of a housing by an intermediate sleeve. The sleeve has an annular recess in its end surface, the end surface being spaced from the shaft. A sealing element extends radially in the annular recess and axially between the shaft and the intermediate sleeve. The axially extending arm of the sealing element has a flange extending behind a radially extending surface of the intermediate sleeve to axially hold the sealing element, with play, to the intermediate sleeve. The sealing element is mounted with prestress on the shaft, to rotate therewith during operation.

摘要： A tensioning arrangement for a drive belt includes a support, a tension roller rotatably mounted on one end of the support, a swivel bearing arranged on the support at a distance from the tension roller, a swivel-damping element in the form of a linear-acting frictional damper having a master piston and a slave piston arranged in and separately frictionally engaging a cylinder, a spring arranged concentrically around the cylinder and coupled to the master piston, and a spring arranged inside the cylinder and coupled to the slave piston. The displacement of the master piston in one direction is opposed by the frictional forces separately acting on both pistons, whereas the displacement of the master piston in the other direction is opposed by the frictional forces acting on only the master piston.

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： A clutch release, in particular for automobile clutches, comprises a sliding sleeve having a radially outwardly directed flange and an annular groove, a clutch release bearing having an outer ring with a flange that slidably abuts the sliding sleeve flange, and a generally oval-shaped spring ring having a pair of mutually parallel guiding surfaces. The spring ring is arranged between the outer ring and the annular groove at points mutually displaced in the axial direction. The bearing is arranged to rotate relative to the sliding sleeve in the circumferential direction within predetermined limits and to move in a radial direction along the guiding surfaces by overcoming a radially acting frictional force between the slidably abutting flanges. The spring ring has a substantially bow-shaped profile and is slotted. The inner ring of the bearing has a radially outwardly directed pressure flange for abutting with the diaphragm spring of a clutch.

摘要： An hydraulically actuated clutch release, in particular for automobile clutches, comprising a housing having a cylindrical portion and a flange in which a port for the intake of a pressure medium is incorporated, a cylindrical sleeve, an annular piston having a flange and slidably arranged between the cylindrical sleeve and the cylindrical portion of the housing, thereby forming a pressure medium-admitting chamber, a clutch release bearing having a non-rotating bearing ring, an outer cylindrical sleeve, and a compression ring. The outer cylindrical sleeve comprises two portions of different inner diameter and a bead connecting the portions. One portion fixedly contacts the non-rotating bearing ring and the end face of the annular piston flange, and the other portion covers a portion of the outer sliding surface of the annular piston. The compression spring is arranged between the bead of the outer cylindrical sleeve and the flange of the housing.
