The interior ramps which control the lockup and free run of the clutch are formed during the operation of drawing the cup.

Torrington Report – Final Documents. The mounted clutch engages when the housing is rotated relative to the shaft in the direction of the arrow marking LOCK stamped on the cup. An installation tool similar to the one illustrated must be used in conjunction with a standard press. If the housing has a shoulder, never seat the clutch against the shoulder.
Never hammer the bearing into its housing even in conjunction with the proper assembly mandrel. To realize the advantages of the expected closer radial internal clearance of the extraprecision bearing, the user must have the capability of producing housing bore and shaft raceway diameters to the close tolerances indicated by the tabular data on the facing page.
Amount of RecessChamferMake sure that the housing bore is chamfered to permit easy introduction of the clutch and bearing or the clutch unit.
The total radial clearance of an installed DC bearing results from the build-up of manufacturing tolerances of the housing bore, inner raceway o. Through bored housings are always preferred. When closer control of clearance is required, the user may select N6 housing bore and h5 inner raceway o. Details of shaft design for sealed bearings are given in the Engineering section of this catalog. The sketches on these pages illustrate some of the many possible uses.
Applications in which there are overhanging or overturning loads should incorporate bearings which will maintain alignment between the shaft and the clutch housing.

The design provides maximum cage strength consistent with the long life requirements. Precisely formed interior ramps provide surfaces against which the rollers wedge to positively lock the clutch with the shaft when rotated in the proper direction. This reduces the overall assembly width, the number of stocked and ordered parts, and assembly costs as well. Description of Clowe Data.
The proper inspection procedure is as follows: Metric bearings are available with caged rollers as a standard. If clutch is straddled by needle roller bearings, press units into position in proper sequence and preferably leave a small clearance between units.
Wskanikiem wytrzymaoci przekroju na zginanie wzgldem osi obojtnej nazywamy The larger cross section is indicated by the prefix code letter H. For bearings of nominal metric dimensions, the recommended mounting dimensions shown on the tabular pages are consistent with ISO N7 housing bore and h6 inner raceway o. Through bored and gwinyy housings are preferred. The nominal bore diameter for the bearing, as shown in the table of dimensions on pageis 38 inch.
Where the radial loads are light, the clutch and bearing assembly can be used without additional support bearings. The housing should be of high strength material. Identification, Construction, Special Clutches. Where extremely close control of radial clearance is required for bearings of nominal inch dimensions, extraprecision full complement bearings are available.
The metric bearing user should note that addition of these values to the h6 tolerances given in tables of dimensions results in a standard j6 tolerance. Manufacturing Tolerances and Built-in ClearancesManufacturing tolerance for bearing 0. For example, a bearing with metric nominal dimensions is indicated by the code letter F or HK having open ends and letters BK for closed ends, in the prefix. Published on Apr View 83 Download 1.
Ksiazka Techniczna Lozyska Wiencowe Documents. See page for further discussion of mounting fits. Steel housings are preferred and must be used for applications involving high torque loads to prevent radial expansion of the clutch cups. Kompozytowy system naprawy rur Loctite. Either case hardening or through hardening grades of good bearing gwinyy steel are satisfactory for raceways. Metric Inner Rings Dimensions. Naprawa i ochrona betonu. Costs of the assembly, storing and the aclowe are much reduced, the gwinfy of the production or repair is shorter and the permanence of the product is growing.
Operational mode is controlled by the direction of the clutch or shaft rotation with respect to the locking ramps. For example, after following the size selection procedure outlined on pages E72 to E76, bearing B is selected, but extraprecision tolerances are required. The full complement drawn cup bearing combines maximum capacity and low cost with the advantages of the drawn outer ring. Inch-metric conversions are given for the convenience of the user.

Where volume justifies tooling costs, special clutches may result in a lower unit cost or, in the event of additional costs, may provide an economical solution to an unusual design problem. Magnitude of externally applied torque as well as inertial torque Magnitude of applied radial loads during overrunning Potential for vibration or axial shaft movement within the clutch during engagement Engagement rate, as it pertains to the selection of stainless steel or plastic leaf springs Gwingy lubrication supply during high overrunning speeds External and internal environmental temperatures that can affect clutch performance Lubricant selection effect on clutch engagement Indexing inaccuracies resulting from backlash lost motion Consideration should be given to the Shaft and Housing design requirements such as: Mary Mc Verry, Eng.
If an interference fit is used for the inner ring, the outer ring should be mounted with a clearance fit. If the operating temperature must be outside of the above range or if seals are exposed to unusual fluids please consult calowee Torrington Engineering Sales Office.
