Abstract
The utility model discloses a V belt pulley with adjustable diameter, which is characterized in that the V belt pulley is composed of a plurality of fan-shaped belt pulley units, a sleeve shaft end plate which is provided with an oblong through groove, an end plate, and a fastener. The fan-shaped belt pulley units can move in a radial direction by adjusting the nuts of both ends of the fastener to achieve the purpose for changing the diameter of the V belt pulley. The utility model can be widely used for the V belt stepless speed changing mechanisms, and the variable-speed ratio of V belt stepless speed changing mechanisms can be changed by the utility model. The V belt pulley with adjustable diameter has the advantages of big transmission power and simple structure.
Description
The utility model relates to a kind of vee-pulley, particularly the variable-diameter vee-pulley in the stepless speed changing mechanism of vee belt.
At present, the vee-pulley that is used in the stepless speed changing mechanism of vee belt is integrated type mostly, and the diameter of this vee-pulley is immutable, uses and can't adjust its gear ratio in stepless change machinery.Also having a kind of vee-pulley, is the dovetail groove separated into two parts that it is cooperated with v belt, adjusts the width of dovetail groove by the distance that changes between these two-part, and then realizes the change of stepless speed changing mechanism gear ratio.But because the belt that is enclosed within on this vee-pulley can only be done a spot of radial displacement in the depth bounds of its dovetail groove, the gear ratio of stepless speed changing mechanism is changed not quite, and the power of transmission is also little, complex structure, application area is wideless.
The purpose of this utility model is to provide a kind of variable-diameter vee-pulley, use this vee-pulley can change the gear ratio of stepless speed changing mechanism greatly, and transmission power is big, simple in structure, applied range.
Variable-diameter vee-pulley of the present utility model comprises a main shaft, passes through a key suit one sleeve on this main shaft.Its structural feature is, an end of sleeve is processed with the sleeve end plate that is fixed with one with it, and its other end is equipped with end plate; All radially be milled with the rectangular groove of equivalent amount on this sleeve end plate and the end plate, be fitted with fastening piece in it correspondingly along it.All being set with end face on the fastening piece between sleeve end plate and the end plate is that circumferential car fan-shaped, cylindrical has the sector belt wheel unit of dovetail groove, the both ends of the surface of this sector belt wheel unit radially are processed with the protruding key of rectangular that matches with rectangular groove on sleeve end plate and the end plate along it, its end face center also is drilled with through hole, so that match with fastening piece.
Because variable-diameter vee-pulley of the present utility model is to be made of parts such as plurality of sector belt wheel unit, and each sector belt wheel unit can radially make same moved further along it, thereby realized the stepless variable radius of vee-pulley.Be used in the stepless speed changing mechanism of vee belt, its gear ratio is increased.And simple in structure, transmission power is big, applied range.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a variable-diameter vee-pulley cross-sectional schematic;
Fig. 2 is that the A of Fig. 1 is to partial schematic sectional view.
With reference to Fig. 1, Fig. 2, suit one sleeve 3 on the main shaft 1 of the present utility model, an end of this sleeve 3 is provided with sleeve end plate 10, and this sleeve end plate can be processed into one with sleeve 3, also can be fixed with one after the processing separately separately as required again.The other end of sleeve 3 is equipped with end plate 5.It radially all is milled with the rectangular groove of equivalent amount sleeve end plate 10 and end plate 5 upper edges, be fitted with fastening piece 8 in it correspondingly, between sleeve end plate 10 and the end plate 5 fastening piece 8 on all to be set with end face be fan-shaped belt wheel unit 6, the both ends of the surface of this sector belt wheel unit radially are processed with the protruding key of rectangular along it, so that match with rectangular groove on sleeve end plate 10 and the end plate 5.The end face center of sector belt wheel unit is drilled with the through hole that matches in order to fastening piece 8, and the circumferential car of its cylindrical has dovetail groove, matches with v belt with convenient.When need are adjusted variable-diameter vee-pulley diameter of the present utility model, the sector belt wheel unit on the fastening piece 8 is moved radially along the rectangular groove on sleeve end plate 10 and the end plate 5 as long as unscrew the nut at fastener 8 two ends.When adjusting to required angle, screw the nut at fastening piece 8 two.Thereby realize the change of vee-pulley diameter of the present utility model.
Second embodiment of the present utility model is plate 9 in also being set with on sleeve end plate in first example and the fastening piece 8 between the end plate 5, and quantity of plate is decided by the power of belt wheel in this.Its both sides radially are milled with the rectangular groove that matches with sector belt wheel unit 6 along it, and the quantity of this groove equates with rectangular groove quantity on sleeve end plate 10 and the end plate 5.
Axially is processed with keyway along it in the interior circular hole that the 3rd embodiment of the present utility model is first embodiment's end plates 5, this keyway matches with key 7 on the sleeve 3, and end plate 5 can be endwisely slipped on sleeve 3.
Axially is processed with keyway along it in the interior circular hole that the 4th embodiment of the present utility model is the middle plate 9 among second embodiment, this keyway matches with key 7 on the sleeve 3, and middle plate 9 can be endwisely slipped on sleeve 3.
The 5th embodiment of the present utility model is separately installed with plate washer 4 on the sleeve 3 in the sleeve end plate 10 among above-mentioned four embodiments and end plate 5 outsides, be milled with on it with fastening piece 8 match, quantity equals sleeve end plate 10 and end plate 5 on rectangular groove quantity, be used for the arc-shaped slot of adjusting belt wheel diameter.When adjusting pulley diameters, as long as unscrew the nut at fastening piece 8 two ends, make two baffle plates 4 simultaneously with respect to sleeve end plate and angle of end plate rotation, can realize the change of pulley diameters.
