Snow removing machine
First Claim
Patent Images
1. A snow removing machine comprising:
- a prime mover having an output shaft for outputting power from the prime mover, the output shaft having a proximal end portion close to a body of the prime mover and a distal end portion remote from the body of the prime mover;
a snow-removing work section, having a rotary shaft driven by power from the output shaft of the prime mover to perform snow-removing work;
a drive pulley rotatably mounted on the proximal end portion of the output shaft for free rotational movement relative to the output shaft;
a driven pulley fixedly connected to the rotary shaft of the snow-removing work section;
a transmission belt extending between the drive pulley and the driven pulley; and
an electromagnetic clutch mounted on the distal end portion of the output shaft with the drive pulley disposed between the electromagnetic clutch and the body of the prime mover, the electromagnetic clutch being operative to connect or disconnect the output shaft and the drive pulley for selectively effecting or blocking power transmission between the output shaft and the drive pulley.

Abstract
A snow removing machine having an electromagnetic clutch mounted to an output shaft of an engine, and a drive pulley. The electromagnetic clutch is mounted to a proximal end of the output shaft to be remotely separate from the engine. As a result, heat generated in the engine during operation thereof is not directly transferred to the electromagnet clutch whose magnetic force generated during operation is not deteriorated. The drive pulley is mounted to the output shaft at an area closer to the engine. The drive pulley has a lower weight than the electromagnet clutch, thereby mitigating load to be exerted to a part which supports the output shaft.

7. A snow removing machine comprising:
- a prime mover having an output shaft for outputting rotary power from the prime mover, the output shaft having a proximal end portion proximate to a body of the prime mover and a distal end portion remote from the body of the prime mover;
a snow-removing section having a rotary shaft for performing snow removal in response to rotation of the rotary shaft;
a drive pulley rotatably mounted on the output shaft;
a driven pulley fixedly connected to the rotary shaft;
at least one transmission belt extending around the drive and driven pulleys for transmitting rotary power from the drive pulley to the driven pulley to thereby rotationally drive the rotary shaft; and
an electromagnetic clutch mounted on the distal end portion of the output shaft with the drive pulley disposed between the electromagnetic clutch and the body of the prime mover, the electromagnetic clutch being switchable between a clutching state for connecting the drive pulley to the output shaft for rotation therewith and a non-clutching state for disconnecting the drive pulley from the output shaft. - View Dependent Claims (8, 9, 10, 11, 12)
