Abstract
The invention discloses a pulley comprising a pulley body, at least one winding of pulley slot on the outer annular surface of the pulley body; the outer slot wall of the outside pulley slot is provided with a ventilation hole which passes through the outside of the slot wall and the pulley slot; the inner slot walls between the adjacent pulley slots are provided with a continuous seam which passes through the pulley slots at the two sides. Owing to the ventilation hole arranged at the side of the pulley, when the pulley whirls in a high speed, wind is blown into the pulley slot through the ventilation hole and cools down a driving belt; besides, owing to the continuous seam, the wind can be blown into other pulley slots in the middle part, thereby achieving the effect of cooling driving belt in the middle part. With the driving of the pulley, the heat is emitted out, thereby reducing the working temperature of the driving belt and prolonging the service life of the driving belt.
Description
Technical field
The present invention relates to a kind of belt transmission equipment technical field.
Background technique
At present, existing belt pulley normally processes the belt grooves of at least one circle on the outer peripheral surface of belt pulley.During use, belt is embedded in the belt grooves, drive belt transmission, drive driven pulley by belt again and rotate, thereby reach the purpose of transmission by drive pulley.In transmission process, rely on the frictional force between belt pulley bottom or side and the belt to carry out transmission, these frictions can produce very big heat, these heat accumulations are on belt grooves or belt, be difficult to leave, temperature when making belt work improves greatly, has accelerated the aging speed of belt, and significantly reduce working life.
Summary of the invention
The purpose of this invention is to provide a kind of belt pulley, to improve the working life of drivign belt with vent hole.
In order to realize above purpose, the technical solution used in the present invention is: a kind of belt pulley, comprise wheel body, and the outer peripheral surface of wheel body is provided with at least one circle belt grooves, and the external groove sidevall of outermost belt grooves is provided with the vent hole that connects the cell wall outside and belt grooves; Described vent hole is the inclination vent hole, and described vent hole tilts towards the direction that belt pulley rotates from inside to outside.
Described wheel body is provided with at least two circle belt grooves, and the internal groove side wall between the described adjacent belt grooves is provided with the straight joint that connects its both sides belt grooves.
The position of the straight joint on the described internal groove side wall with or quantity identical with vent hole on the described external groove sidevall.
The outer openings of described vent hole is greater than interior side opening.
Described vent hole evenly is provided with at external groove sidevall upper edge circumference.
Described belt grooves is v belt groove or trapezoidal belt groove, and the interior side opening of described vent hole is arranged on the bottom of belt grooves.
The sectional shape of described vent hole is ellipse, bar shaped or circle.
The sectional shape of described straight joint is ellipse, bar shaped or circle.
The invention has the beneficial effects as follows: because the vent hole that the present invention is provided with in the belt pulley side, when the belt pulley high speed rotating, wind is blown in the belt grooves by vent hole, drivign belt is cooled off, and since straight joint setting can make wind go in the middle of in other the belt grooves, reach the effect of the interjacent drivign belt of cooling.Along with the transmission of belt pulley, these heats are distributed, thereby lowered the operating temperature of drivign belt, prolonged the working life of drivign belt.
In addition, because vent hole in the even setting of external groove sidevall upper edge circumference, has guaranteed the rotary balance of belt pulley; Increase the quantity of vent hole, when belt pulley rotates, improved radiating efficiency; Because being obliquely installed of vent hole, true dip direction are the direction that belt pulley rotates, and are beneficial to being blown into of wind when belt pulley rotates; Because the little opening setting of vent hole of belt grooves inboard makes fashionable the obtaining of wind quicken and concentrate, and has improved the effect of blowing to the drivign belt cooling.
In addition, when belt pulley was Vee pulley V, arcuate gap was formed on the bottom of v belt and v belt groove, because the interior side opening of described vent hole is arranged on the bottom of belt grooves and connects arcuate gap, the wind that is blown into from vent hole forms wind eddies stream, better heat-radiation effect arcuate gap.
In addition, the shape of vent hole of the present invention and straight joint can be circle, ellipse or bar shaped.Because the opening of vent hole and straight joint can not be too big, otherwise influence the mechanical strength of belt pulley, when guaranteeing that vent hole and straight joint opening area are constant, select other shapes such as ellipse or bar shaped for use, can improve the ventilation of vent hole and straight joint, thereby improve the radiating effect of drivign belt.
