  • Publication number: 20190232298
    Abstract: A cone crusher apparatus having a bowl liner removably mounted within a bowl. A wedge is radially adjustable between an inside surface of the bowl and an outside surface of the bowl liner. The wedge moves radially between a rotation-preventing position and a rotation-permitting position. In the rotation-preventing position, the wedge is in simultaneous abutment with the bowl and bowl liner and through that simultaneous abutment immediately develops a maximum holding force such that relative motion between the bowl liner and bowl in a first rotational direction is prevented. In the rotation-permitting position, the wedge is not in simultaneous abutment with the bowl and bowl liner and at least some relative motion between the bowl liner and bowl in the first rotational direction is permitted.

  • Publication number: 20120121214
    Abstract: Embodiments herein generally provide a pin-guided roller bearing utilizing an interference fit, e.g., a shrink fit and/or press fit, to strengthen the connection between the pins and the cage, which may increase the durability of the cage. Various embodiments generally include a pin-guided cage and a plurality of roller elements coupled to the cage, wherein the pins are coupled to the cage by an interference fit. The roller bearing may further include a top race and a bottom race, coupled to opposite sides of the roller elements. The roller bearing may generally facilitate the movement of the top race relative to the bottom race while subject to a substantial load on the toprace.

  • Patent number: 7806948
    Abstract: A filter system for ambient air to remove airborne particulates in air that is to be used for engine operation. A filter media that is pervious to air and impervious to the particulates may be coupled to a filtered air chamber, which in turn may supply filtered air to the engine's air intake system. In various embodiments, the engine's air intake may be used utilized to draw air through the filter media into the filtered air chamber. An pressurized gas pulsing system may be used to periodically urge reverse airflow through the bag walls to maintain the permeability of the walls to the clean air.

  • Publication number: 20070164516
    Abstract: A seal for sealing around a drive shaft protruded through a hole or opening in a liquid containing box. The seal includes a seal housing secured to the box and having a center opening, and a flinger sleeve secured to the drive shaft and projected through the center opening of the seal housing. The sleeve includes an inner wrap-around flange that extends axially inward and radially outward of the center opening to repel liquid directed towards the box hole. A clamping ring provides radial location setting of the seal housing relative to the shaft and axial location setting of the sleeve relative to the seal housing while also providing clamping of the sleeve to the drive shaft.

  • Publication number: 20070051837
    Abstract: A rock crusher including a bowl and cone mounted to define a determined but fluctuating spacing in which rocks are received and crushed. A relief mechanism provides a resistive force and permits opening of the determined spacing when the crushing forces are sufficiently large to overcome that resistive force. A programmable proximity sensor detects the opening of the determined spacing and discriminately signals the occurrence of said opening. The programmable proximity sensor enables the setting of a specified opening beyond which a change in state occurs, both when the specified opening is exceeded and when said specified opening is reestablished.
