IPC: B62D55/253
Filed: 1987-04-16
Abstract: PURPOSE:To prevent a rolling ring from getting out of a crawler by forming a derailment preventing projection 5 contacting closely both sides of a guide rail in a core bar. CONSTITUTION:A plurality of core bars 2 are embedded parallel to each other perpendicular to the longitudinal direction of a crawler body 1 and respectively formed with a pair of left and right guide rails 3 projecting more inside than the inner peripheral surface of crawler body 1. A derailment preventing projection 5 is formed spaced a fixed interval from said guide rail 3. The travelling surface 104A of a guide ring body 104 is formed of the guide rail 3 and a rubber projection 7. Thus, a derailment prevent member 104B is located between the guide rail 3 and said projection 5 to prevent the derailment.

IPC: F04D25/10
Filed: 1988-04-15
Abstract: PURPOSE:To facilitate the assembly of an electric fan oscillating device by forming a projection area on the output shaft of an oscillating motor in such a state where it can freely be engaged with a shaft hole which is provided in the eccentric cam and corresponds to the projection area, in an electric fan whose oscillation is obtained by vertically reciprocating a slide cam due to the rotation of an eccentric cam. CONSTITUTION:When an eccentric cam 11 fixed to the output shaft 4a of an oscillating motor 4 is rotated by the motor, a slide cam 12 is guided by each guide pin 14, 14 so as to be reciprocated in its vertical direction. Then the reciprocation of the slide cam 12 results in the vertical oscillation of an electric fan through a rod 13, a bracket metal 3, and a frame 2. In this case, a cam retainer 10 is fixed to the rear surface of a main motor 1 to control the slide cam 12 and the eccentric cam 11 so that they do not move back and forth. And the oscillating motor 4 is arranged on the back side of the cam retainer 10, and a projection area 4b made by inserting a pin into the output shaft 4a is engaged with a recess area 11b which is formed in the shaft hole 11a of the eccentric cam 11, so that power can be transmitted into the eccentric cam 11.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To make a spindle itself lighter in weight, and to shorten a span of start-up time to the specified revolution of this spindle and its stopping time by having the whole of a hollow tubular body composed of an integral ceramic sintered compact in the aggregate. SOLUTION: Wall thickness of a rear part rather than an interior part of a holder body, for example, a surface part 9B-the thinnest part in a cylinder is made into that of at least more than 0.1 times and less than 0.3 times to a partial cylinder outer diameter for thickening, and likewise the wall thickness is formed into a size of at least more than 0.02 times and less than 0.06 times to the full length of a hollow cylindrical sphere 1 or each full length of three surface parts 9A, 9B and 9C. Since the wall thickness of a ceramic spindle 1 at the more tip side than a stepped part 7 installed with the tool holder body is largely formable owing to the diametral contraction of wall diameter, it is desirable even in the structural point of view.
