Abstract
The invention relates to a hub (1) with a hub opening (2) in the front face (8), for press-fitting to a base body, whereby the hub (1) comprises a insertion region (A2), tapering in the pressing direction, characterized in that a cylindrical section is arranged between the front face and insertion region (A2), viewed in the pressing direction. Furthermore, a hub (1) with a tapering insertion region (A2) is disclosed, whereby said insertion region (A2) has a length of 40% to 96% of the total length (L) of the hub (1). The invention further relates to a camshaft with at least one cam (9), associated with said hub (1).
Claims16
A press-fitted hub system comprising:
- a base body formed as a shaft and having at least one region of material aggregate adapted to have a diameter larger than the diameter of the shaft;
- and
- at least one hub having a hub opening in a front face for pressing onto the base body, whereby the hub opening has an insertion area tapering in a press-on direction, a first cylindrical section arranged as viewed between the front face and insertion area, and a second cylindrical section arranged on the opposite side of the insertion area with reference to the first cylindrical section;
- wherein the length of the first cylindrical section is about 2% to 30% of the entire length of the hub;
- wherein the diameter of the first cylindrical section of the hub opening is at least the same size as the largest diameter of the base body, on which the hub is to be pressed;
- wherein the insertion area is tapered in a press-on direction, and the diameter of the first cylindrical section greater than the diameter of the second cylindrical section.
A press-fitted hub system comprising:
- a base body formed as a shaft and having at least one region of material aggregate adapted to have a diameter larger than the diameter of shaft;
- a camshaft having at least one cam, wherein the cam having a hub opening for receiving the base body, wherein the hub opening has an insertion area tapered in the press-on direction, characterized in that, viewed in the press-on direction, a first cylindrical section is arranged between the front face and the insertion region;
- wherein the length of the first cylindrical section is about 2% to 30% of the entire length of the hub;
- wherein the hub further comprising a second cylindrical section, the second cylindrical section with reference to the first cylindrical section is arranged on the opposite side of the insertion area, and
- wherein the material aggregate being adapted to deform when the insertion area and the second cylindrical section is pressed thereon;
- wherein the insertion area is tapered in a press-on direction, and the diameter of the first cylindrical section greater than the diameter of the second cylindrical section.
