  • Gear unit and a method for heating lubricant oil of a gear unit
    Patent number: 10309518
    Abstract: A gear unit comprises shafts (101, 102) for connecting to an external mechanical system, at least one gear stage (103) between the shafts, a lubricant oil room (104) for storing lubricant oil, an oil channel (105) for transporting the lubricant oil from the lubricant oil room to the at least one gear stage, and an immersion heater (106) for heating the lubricant oil flowing in the lubricant oil room towards an inlet of the oil channel. The gear unit further comprises a mechanical flow guide (108) located in the lubricant oil room and configured to modify flow of the lubricant oil flowing towards the inlet of the oil channel so as to increase flow velocity of the lubricant oil on the surface of the immersion heater. The increased flow velocity on the surface of the immersion heater makes it possible to use higher heating power without damaging the lubricant oil.

  • Corner rack
    Patent number: 10281015
    Abstract: The invention is a corner rack with one front face that has teeth. A corner rack is a linear gear interface that can be placed in corners, such that the teeth face out from the corner at an angle, rather than running parallel with the walls. The teeth of the corner rack have a profile that can engage with the profile of a silent chain. The combination of the corner rack and silent chain allows an attached motor to be distanced from the corner rack, so that a lifting device driven by the corner rack and silent chain can be placed in and utilized in corners. This leads to increased versatility and efficiency.

  • Multi-gear cassette and damping device
    Patent number: 10253865
    Abstract: The invention relates to a damping device on a multi-gear cassette for a rear wheel of a bicycle, wherein percussive forces produced by the chain members running from the slack span of the chain onto the sprocket are damped. This is achieved by damping the chain in the region of the chain run-in on the sprocket where no loads are borne. In one embodiment, a damping ring is provided for the purpose of supporting the chain link plates, and the tooth contour of the tooth flank which does not transmit load force is set back, and the tooth root space according to the invention is recessed toward the hub center. As such, when the chain is fed in to the sprocket, the chain link plate contacts the damping ring rather than the chain roller impacting the tooth flank or the tooth base.
