Abstract
A washer device is disclosed including two annular components each having a main face arranged to contact the main face of the other component. Each main face has surface regions of different levels along an axis of the component, such as a step and/or a helical ramp. Relative rotation of one component with respect to the other about their common axis alters the effective thickness of the washer device. The washer device 1 further includes at least one radial projection on one of the annular components arranged to engage with a corresponding notch on the other annular component such that the annular components may be oriented in predetermined angular positions corresponding to different predetermined effective thicknesses of the washer device.
Claims14
A washer device, comprising:
- two annular components, each having a main face arranged to contact the main face of the other component, each main face having surface regions of different levels along an axis of the component, whereby relative rotation of one component with respect to the other about their common axis alters the effective thickness of the washer device;
- at least one projection extending radially from one of the annular components and arranged to engage with at least one corresponding notch on the other annular component such that the annular components may be oriented in relative predetermined angular positions corresponding to different predetermined effective thicknesses of the washer device;
- and,
- wherein the at least one projection is a plurality of radial projections extending outwardly from an outermost periphery of one component arranged to engage with a same number of corresponding notches on the other component.
A washer device, comprising:
- two annular components, each having a main face arranged to contact the main face of the other component, each main face having surface regions of different levels along an axis of the component, whereby relative rotation of one component with respect to the other about their common axis alters the effective thickness of the washer device;
- at least one projection extending radially from an outermost periphery of one of the annular components and arranged to engage with at least one corresponding notch on the other annular component such that the annular components may be oriented in relative predetermined angular positions corresponding to different predetermined effective thicknesses of the washer device;
- wherein the at least one projection is a plurality of radial projections extending outwardly from an outermost periphery of one component arranged to engage with a same number of corresponding notches on the other component;
- and
- wherein the surface regions of different levels of each main face are formed by a helical ramp extending around the circumference of its main face from a higher thickness region to a lower thickness region, and wherein the helical ramps of the two annular components cooperatively engage to adjust the effective thickness of the washer device through relative rotation.
A washer device, comprising:
- two annular components, each having a main face arranged to contact the main face of the other component, each main face having surface regions of different levels along an axis of the component, whereby relative rotation of one component with respect to the other about their common axis alters the effective thickness of the washer device;
- at least one projection extending radially from an outermost periphery of one of the annular components and arranged to engage with at least one corresponding notch on the other annular component such that the annular components may be oriented in relative predetermined angular positions corresponding to different predetermined effective thicknesses of the washer device;
- wherein the at least one projection is a plurality of radial projections extending outwardly from an outermost periphery of one component arranged to engage with a same number of corresponding notches on the other component;
- wherein the surface regions of different levels of each main face comprise both at least one step and at least one helical ramp forming a gradual transition between different levels;
- and,
- wherein the at least one step and the at least one helical ramp of one component are arranged to cooperatively engage with corresponding at least one step and at least one helical ramp of the other component to provide thickness adjustments through relative rotation of the components.
