Abstract: A clutch arrangement having a first coupler mounted for rotation with a first input gear, a second coupler mounted for rotation with a second input gear, and an input-gear selector mounted for rotation with an input shaft and positioned between the first and second couplers. The input-gear selector is movable on the input shaft relative to the first and second couplers. Engagement of the input-gear selector with the first coupler drives rotation of the first input gear with rotation of the input shaft, and engagement of the input-gear selector with the second coupler drives rotation of the second input gear with rotation of the input shaft.

Abstract: The disclosure generally relates to transmission of torque from a housing to a drive shaft. More specifically, the disclosure relates to configuration of contact surfaces between a housing and shaft to increase transmission of torque. Tools such as drilling tools often require torque to be transmitted from a rotating housing to a driveshaft. This is often accomplished through threaded connections or splines. A threaded connection can be effective for transmitting torque by allowing two pieces to be securely joined by rotating and tightening to a specified torque. A splined connection can also be effective for transmitting torque, providing sufficient clearance for one member to slidingly receive the other without rotating and torqueing. A tapered polygon is another effective way to transmit torque that by virtue of tapering can take up clearances between the torque carrying components. As such, the tapered polygon does not introduce significant stress concentrations into the components.

Abstract: A motion conversion apparatus (400, 500) comprises at least one set including a rodrack assembly (110) between two gearshaft member end sections (155), and a gearshaft member mid section (156) between the two gearshaft member end sections (155). The rodrack assembly (110) comprises a first gear connection member (120) and two guide members (140). The gearshaft member mid section (156) comprises a second gear connection member (160) configured to engage with the first gear connection member (120). The two gearshaft member end sections (155) each comprise a guiding surface arrangement (170) configured to contact the two guide members (140). The rodrack assembly (110) is configured to provide rotation of the gearshaft member mid section (156) about a rotational axis (A) by reciprocating linear motion of the rodrack assembly (110) along a first spatial dimension (D1) orthogonal to the rotational axis (A), or vice versa.

Abstract: The present invention provides a power assembly, including: a motor, a fixing base and a propeller. The fixing base is sleeved over a motor rotation shaft and is fastened to a base body of the motor, and the fixing base is provided with a first clamping portion. The propeller includes a base portion and a blade extending from the base portion, and the base portion is provided with a second clamping portion clamped to the first clamping portion. The propeller is detachably connected to the motor by engaging the first clamping portion with the second clamping portion, so that the propeller can be effectively prevented from loosening from the motor during the vibration or acceleration, and is easy to disassemble/assemble and carry.

Abstract: A driving apparatus includes a drive output member configured to, when driving a member to be driven, receive a first force from the member to be driven in a direction in which the drive output member comes off a rotation shaft of a motor, and when driven by a drive transmission member, receive a second force from the drive transmission member in a direction opposite to that of the first force. The second force is equal to or greater than the first force.

Abstract: An electrical food preparation device including a drive mechanism (3) rotated by a motor and a working tool (4, 5, 6, 7) including a bushing that removably engages on the drive mechanism, the drive mechanism including a section provided with at least one drive ramp that mates with a complementary drive ramp carried by said bushing in order to rotate said working tool, the drive ramp having an inclination designed such that the rotation of the drive mechanism in the direction of rotation of the motor generates a force on the bushing that tends to keep it engaged on the drive mechanism, the drive mechanism also including at least one retaining surface (33) that comes into contact with a stop carried by the working tool when the drive mechanism rotates in the reverse direction, the retaining surface and the stop having shapes that mate each other to prevent the bushing from rising back up along the drive mechanism when the motor stops suddenly, wherein the retaining surface is provided on a different part of the drive mechanism from the section supporting the drive ramp.

Abstract: An apparatus used for winding or unwinding winch straps includes a clevis, a first engagement plate, and a second engagement plate. Both the first engagement plate and the second engagement plate contain a lobe, a lug, an oblong body, and a plate pinhole which are rotatably connected to the clevis with a plate retaining pin which traverses through the plate pinhole. When in use, a power tool is attached to a tool-receiving slot, which is integrated into a structural body of the clevis. Next, the lobe of the first engagement plate and the second engagement plate establishes a connection with the spool hub the apparatus is being used on. Simultaneously, the lug of the first engagement plate and the second engagement plate are pressed against the spool hub. Therefore, the force is transferred from the power tool to the spool via the introduced apparatus.
