  • Patent number: 11850816
    Abstract: An arbor press includes a limiter for limiting load and/or travel of a ram used to press on an object. The ram includes a pair of pieces, a shaft and a sleeve, which are capable of relative translation, modulated by the spring. The spring may be preloaded, and configured to prevent overloading of the object, by limiting the transmission of force through the ram. The ram may also be configured to limit travel of the ram. The arbor press may include gearing to translate rotational movement of a handle to translational movement of the ram. The gearing may include a rack that is part of or is coupled to the shaft, and a pinion that is connected to the handle. Parts of the arbor press may be enclosed in a housing, to contain debris from metal-to-metal sliding in the arbor press, facilitating use in clean rooms.
