Abstract
This invention relates to a quick replaced impeller of smoke exhauster without tool installation an demounting impeller. It contains the impeller sleeved on the driving axle through sleeve on hub, a ball hole set sleeve wall for holding ball, sliding bush and spring set outside of axle sleeve, the sliding bush having small and large holes, when sliding bush slid to one end the small squeezing ball in ring groove in driving axle and holding impeller on driving axle, when sliding to another end the ball releasing from ring groove entering large hole of sliding bush for demounting impeller. Said invention can be used in scavenger fan and exhauster.
Description
Technical field the present invention is a kind of rapid-replacing impeller, belongs to the smoke ventilator field
The existing smoke ventilator impeller of background technique is installed in impeller on the line shaft by screw, because installing space is narrow and small, installation and removal need instrument, safeguards inconvenient.
Summary of the invention the present invention seeks to, the rapid-replacing impeller that provides a kind of not tool using just can mount and dismount.
Technological scheme of the present invention is, a kind of rapid-replacing impeller has wheel blade and wheel hub, and wheel hub one side is stretched out an axle sleeve, it is characterized in that, circumferentially one encloses radially ball hole on the axle sleeve wall thickness, wherein places ball.Spring and sliding sleeve are enclosed within on the axle sleeve, spring seat is arranged on the axle sleeve, also have the spacing block body axial to sliding sleeve, spring is contained between sliding sleeve and the spring seat, sliding sleeving hole comprises macropore and aperture, can contain whole ball between big hole wall and ball hole wall, can contain the part ball between little hole wall and ball hole wall, sliding sleeve is positioned at the two ends of stroke, and ball lays respectively in sliding sleeve macropore and the aperture.
Impeller is enclosed within on the line shaft by axle sleeve, when sliding sleeve was positioned at stroke one end, ball was positioned at the sliding sleeve aperture, because little hole wall and ball hole wall can only contain the part of ball, ball is just clamp-oned in the annular groove on the line shaft by the sliding sleeve aperture, and impeller is stuck on the line shaft.Sliding sleeve is positioned at the stroke the other end, and ball is positioned at the sliding sleeve macropore, because big hole wall and ball hole wall can contain whole ball, ball just can withdraw from from the line shaft annular groove, thereby unloads impeller.
Embodiment is for ease of making, axle sleeve 2 makes an end limited step, this step double as spring seat, hole wall has a circle taper hole, and ball 4 is not mounted in it and can inwardly comes off, and sliding sleeve 3 and spring 5 are enclosed within on the axle sleeve, spring is between sliding sleeve aperture end face and axle sleeve limited step, then axle sleeve is not had limited step one end to be welded on the wheel hub, the wheel hub end face constitutes another limited step of axle sleeve, and axle sleeve is enclosed within on the line shaft 7.One annular groove is arranged on the line shaft, and after sliding sleeve was shifted onto the upper end by spring, ball was clamp-oned in the annular groove by the sliding sleeve aperture, can not throw off thereby impeller is stuck on the line shaft, and after the pulling sliding sleeve slided into the lower end, ball can withdraw from annular groove and enter in the sliding sleeve macropore, thereby unloads impeller.There is square hole the axle sleeve lower end, and the square toes of line shaft can insert impeller, and guard shield 6 is contained in and is used on the sliding sleeve prevent dust.
