A speed change operation apparatus includes a pivotal body operatively connected to a trunnion shaft to be pivotally displaced in response to an operational displacement by an operational tool, a positioning body operatively coupled with the pivotal body so as to be pivotally displaced in response to a pivotal displacement of the pivotal body, a main urging mechanism for applying an urging force to the pivotal body via the positioning body for returning the pivotal body from an operational position to the neutral position, and an auxiliary urging mechanism for applying an auxiliary urging force to the pivotal body for returning the pivotal body from the operational position to the neutral position. The returning urging force by the main urging mechanism when the trunnion shaft is located at the neutral position is stronger than the returning urging force by the main urging mechanism when the trunnion shaft is located at the operational position. And, the auxiliary urging force by the auxiliary urging mechanism when the trunnion shaft is located at the neutral position is weaker than the auxiliary urging force by the auxiliary urging mechanism when the trunnion shaft is located at the operational position.

Continuous casting gearbox comprising heat shielding

Номер: US20120024106A1

Автор: Herbert Brotzki

Принадлежит: Sms Siemag AG

The invention comprises a continuous casting gearbox ( 1, 10, 100 ) used for operating rolls or rollers in a continuous casting plant. The gearbox ( 1, 10, 100 ) has water-bearing chambers ( 2, 20, 200 ) for shielding against heat radiation and hot convection. Due to the fact that the continuous casting gearbox ( 1, 10, 100 ) is surrounded by the chambers ( 2, 20, 200 ), it is possible to achieve an effective shielding, thus being able to avoid gearbox damage caused by an gearbox oil overheat.

A ratchet assembly includes an elongated shaft, a gear housing, a ratcheting member, and an arm. The elongated shaft can have a gear and be supported by the gear housing to allow rotation about a primary axis of the shaft. The ratcheting member can mount in the housing and be biased toward the gear to engage with the gear hindering relative rotation about the shaft axis in a first direction and allowing rotation about the shaft axis in a second direction opposite the first direction. The ratcheting member can rotatably mount within the housing about a second axis. The arm can couple to the gear housing in a first configuration to provide torque to rotate the housing about the shaft axis in the first direction when the arm is pressed downward. The arm can also be coupled to the gear housing in a second configuration to rotate the housing about the shaft axis in a second direction opposite the first direction when the arm is pressed downward.

A flywheel assembly is described which is suitable for use as a compact power storage device. The assembly comprises a housing, a flywheel coupled to a shaft which is rotatably mounted in the housing via bearings, a primary chamber which is defined within the housing and contains the flywheel, and a secondary chamber which is defined within the housing and contains the bearings. Furthermore, it includes a molecular pump driven by the shaft for pumping gas molecules from the primary chamber to the secondary chamber. Location of the bearings in a high pressure chamber inhibits off-gassing from the bearing grease. Furthermore, any such off-gassing under load will not increase the gas pressure in the first chamber containing the flywheel as it is separate from the secondary chamber containing the bearings.

A bicycle crank arm has a body member and a cover member that at least partially overlies a peripheral surface of the body member. The body member includes a crank axle attachment portion that has a crank axle receiving opening. A slit extends from the peripheral surface of the body member to the crank axle receiving opening. A fastener bore extends transversely through the slit for adjusting the crank axle receiving opening in size. The peripheral surface of the body member has abutments located on opposite sides of the slit. The abutments are arranged relative to the slit such that the abutments move closer together as the crank axle attachment portion is squeezed to decrease the crank axle receiving opening in size. The cover member contacts the abutments and moves with the abutments as the crank axle attachment portion is squeezed to decrease the crank axle receiving opening in size.

Vibration damper

Номер: US20130309097A1

Автор: David Miller

Принадлежит: Rolls Royce PLC

Vibration damping is important with regard to such components as hollow turbine blades in gas turbine engines. Traditionally damping has occurred through damping elements secured at the root or tip of such blades. Such damping is not optimised and results in potential problems with wear in operational life. By providing a tube of deformable material which can be located within a hollow cavity it is possible to provide an element which through friction engagement can absorb vibration energy and therefore damp such vibration. The tube incorporates a number of cuts and/or grooves in an appropriate pattern in order to define a deformation profile once the tube is expanded in location. The tube is secured in position internally upon an expandable element which is typically an inflatable device. Once in position the tube is retained in its expanded deformable profile and the engagement between the tube and the hollow cavity wall surface results in energy absorption through vibration episodes. It is also possible to provide a tube formed from a shape memory alloy which will expand of its own right in location to engage the hollow cavity wall surfaces for energy absorption during vibration episodes.

In a sprocket for a bicycle having a radial bearing acting as a bearing portion, an axial load acting on the bearing can be easily adjusted without having to dismount the components of the bicycle after the bicycle has been assembled. An elastomer is used as a component for an anti-rotation mechanism of an adjusting nut which serves to adjust the axial load of the radial bearing, so that an excessive load is not applied on the radial bearing, which would result in a defective rotation. Further, the axial load acting on the radial bearing can be easily adjusted without having to dismount the components of the bicycle after the bicycle has been assembled.

The system uses a high-strength steel rotor rotating in a vacuum envelope. The rotor has a geometry that ensures high yield strength throughout its cross-section using various low-cost quenched and tempered alloy steels. Low-cost is also achieved by forging the rotor in a single piece with integral shafts. A high energy density is achieved with adequate safety margins through a pre-conditioning treatment. The bearing and suspension system utilizes an electromagnet that off-loads the rotor allowing for the use of low-cost, conventional rolling contact bearings over an operating lifetime of several years.
