Abstract:
A rotor for a motor having a rotor core length includes a shaft including a cylindrical portion and a shaft sleeve having a cylindrical opening. The shaft sleeve is coupled to the shaft such that the cylindrical opening and the cylindrical portion define an interference fit. A rotor sleeve extends the rotor core length and includes a cylindrical outer surface and an inner surface. The inner surface is spaced a non-zero distance from the shaft sleeve to define a space. A resilient material is disposed within the space and is bonded to the shaft sleeve and the rotor sleeve.
Abstract:
A connection assembly of a clutch body and a spindle includes: a spindle (1); a clutch body (5) which fixedly connects with said spindle (1). The clutch body (5) includes a clutch disk (11) of generally circular ring shape and several control pillars (7). Said control pillars (7) are provided on the periphery of the clutch disc (11) and are distributed approximately on one same circumference. Several through grooves (8) are provided between said control pillars (7) so as to space the adjacent control pillars (7) apart.
Abstract:
Verbindung, aufweisend eine in eine Hohlwelle zumindest teilweise eingesteckte Welle und ein auf die Hohlwelle aufgestecktes Ringteil, insbesondere eines Spannrings, wobei das Ringteil axial begrenzt ist von einem an der Welle ausgeformten, insbesondere radial hervor stehenden, Bund und/oder das Ringteil an einem oder dem Bund der Welle, insbesondere an einem an der Welle ausgeformten, insbesondere radial hervor stehenden, Bund, anliegt, wobei die Hohlwelle vom Bund beabstandete Schlitze, insbesondere Axialschlitze aufweist, wobei das Ringteil, insbesondere an seiner Innenseite und/oder an seiner Ringöffnung und/oder insbesondere an seinem dem Bund zugewandten axialen Endbereich, eine Fase aufweist, so dass der Innendurchmesser des Ringteils in dem von der Fase überdeckten axialen Bereich größer ist als der Innendurchmesser in demjenigen axialen Bereich, in welchem das Ringteil die Hohlwelle berührt, wobei das Ringteil Verdickungsbereiche aufweist, insbesondere wobei das Ringteil im von den Verdickungsbereichen überdeckten Umfangswinkelbereich eine größere radiale Breite aufweist als in den sonstigen Umfangswinkelbereichen.
Abstract:
A comprehensive water shutoff system is adapted to be connected or associated with a water supply line to a structure. The system comprises a main shutoff valve connected to or in the water supply line and a flow sensing unit for sensing or measuring flow through the supply line. In addition, a controller is operatively connected between the flow sensing unit and the shutoff valve and is operative upon the flow sensing unit sensing one or more predetermined flow conditions, to close the main shutoff valve. Flow sensing unit includes a dual flow path, referred to as a relatively low flow path and a relatively high or main flow path. For relatively low flows being directed through the water supply line, the water flow is directed through the relatively low flow path while the relatively high flow path is closed. In another mode, and in response to the flow rate increasing in the supply line, the relatively high flow path is opened and the water passing through the supply line is directed through this path. In either mode, the flow through the flow sensing unit is sensed and upon certain flow conditions being met (such as uninterrupted flow of water for a selected time period), the controller is operative to close the main shutoff valve.
Abstract:
A frictionally press-bonded member includes a steel pipe, and a stab. The steel pipe has opposite ends. The stab is frictionally press-bonded to at least one of the opposite ends of the steel pipe. The steel pipe is subjected to a normalizing treatment before being frictionally press-bonded to the stab.
Abstract:
A method for attenuating vibration in a driveline having a shaft assembly that transmits torque between first and second driveline components. The shaft assembly can have a hollow shaft member and at least one liner. The liner has a mass and a stiffness that are tuned such that the liner is a tuned resistive absorber for attenuating shell mode vibrations as well as at least one of a tuned reactive absorber for attenuating bending mode vibrations and a tuned reactive absorber for attenuating torsion mode vibrations. The tuned liner is inserted into the shaft member.
Abstract:
A propshaft assembly includes a shaft structure having a hollow cavity and an insert member being positioned within the hollow cavity and engaging the shaft structure. The shaft structure vibrates in response to receipt of an input of a predetermined frequency such that a shell mode anti-node is generated. The insert member is located at a position that approximately corresponds to the anti-node and has a compressive strength that is tailored to an anticipated displacement of the anti-node to thereby attenuate vibration of the shaft structure.
