Specific embodiment
Below with reference to embodiment, the present invention will be further described, but is not limited to the content on specification.
The invention discloses a kind of belt pulleys, including price fixing 10 and Moving plate 20, Moving plate 20 to be movably disposed at price fixing 10
On, Moving plate 20 can pass through the mobile relative distance adjusted between price fixing 10；Price fixing 10 and Moving plate 20, which are oppositely arranged and are formed, to be used for
The belt grooves 60 of belt 30 are placed, the groove width of belt grooves 60 is gradually subtracted by the axis direction of opening towards the price fixing 10 of belt grooves 60
It is small, change the groove width of belt grooves 60 when Moving plate 20 adjusts the relative distance with price fixing 10, so that belt 30 and 10 axis of price fixing
Between distance change.The present invention passes through 10 He of price fixing by price fixing 10 and the Moving plate 20 being movably disposed on price fixing 10
Moving plate 20 forms belt grooves 60, when needed, can be by changing belt grooves 60 when the relative distance of transfer disk 20 and price fixing 10
Groove width so that belt 30 between 10 axis of price fixing at a distance from change, to realize different transmission ratios, realize the electrodeless tune of air-conditioning
Section meets static pressure requirement.
In the above-described embodiments, the first contact surface 11 is provided on the side opposite with Moving plate 20 of price fixing 10, on Moving plate 20
It is provided with second contact surface 21 corresponding with the first contact surface 11, forms skin between the first contact surface 11 and the second contact surface 21
Trough of belt 60.The width of belt 30 is matched with the groove width of belt grooves 60, the width of belt 30 by outer lateral belt grooves 60 slot bottom by
It is decrescence small.Since belt 30 and belt grooves 60 match, and the width of belt 30 is gradually subtracted by the slot bottom of outer lateral belt grooves 60
Small, when increasing at a distance from price fixing 10 is between Moving plate 20, the groove width of belt grooves 60 becomes larger, the first contact surface 11 and the second contact surface
Relative distance between 21 also accordingly becomes larger, so that belt 30 can be made mobile to slot bottom direction, thus reduce with 10 axis of price fixing it
Between distance also correspond to reduce belt 30 to machine shaft 90 since price fixing 10 is arranged on machine shaft 90
Distance, therefore, to change transmission ratio.In addition, since the distance between belt 30 and machine shaft 90 reduce, thus also corresponding
The elasticity for reducing belt 30 and belt pulley cooperation realizes that air-conditioning electrodeless adjustment meets static pressure requirement.And it when price fixing 10 and moves
When distance between disk 20 reduces, the groove width of belt grooves 60 reduces, the relative distance between the first contact surface 11 and the second contact surface 21
Also corresponding to reduce, so that belt 30 can be made mobile to 60 opening direction of belt grooves, thus increase between 10 axis of price fixing away from
From the distance of belt 30 to machine shaft 90 being increased, therefore, to change transmission ratio.In addition, due to belt 30 and motor
The distance between shaft 90 increases, to also increase accordingly the elasticity of belt 30 and belt pulley cooperation, realizes that air-conditioning is electrodeless
Adjusting meets static pressure requirement.
In the above-described embodiments, rack gear is provided on belt 30 and the contact surface of belt grooves 60.It, can be with by increasing rack gear
It realizes and preferably cooperates between belt 30 and belt grooves 60, prevent from skidding, improve transmission efficiency.
