The inner diameter of the cylindrical tube and the inner diameter of the sleeve are identical, and the cone slope of the sleeve and the slope of the inner cone hole of the transmission wheel are corresponding. The inner diameters of the points on the sleeve are identical, and the inner diameter of the sleeve is larger than the diameter of the transmission shaft, and the sleeve is provided with a general long opening along the whole axial length. The cylindrical tube of the conical sleeve, which is provided with outer screw threads, is provided with at least one cushion ring and at least one screw nut. The utility model has the advantages of convenient disassembly and no damage for equipment and parts.
Description
The utility model relates to a kind of transmission device, particularly a kind of fixing device that is used for drive wheel and transmission shaft.
Fixing locking methods that adopt key, jackscrew or the tapered slope on transmission shaft and the drive wheel is fixed between existing drive wheel and the transmission shaft with locking nut more.Its shortcoming is the installing/dismounting difficulty, and wheel endoporus, axle, key and keyway are easy to wear.Working life is short, and maintenance is frequent, especially, makes drive wheel and transmission shaft decentraction to produce vibration during rotation when fastening with key or jackscrew, causes the increase of power consumption and noise, the life-span of having reduced bearing and equipment.
The purpose of this utility model provides a kind of installation and the drive wheel of convenient disassembly and the securing means between the transmission shaft.
The purpose of this utility model realizes by following scheme.
A kind of fixing device that is used for fixing drive wheel and transmission shaft of the present utility model comprises:
One opens the internal taper hole on the transmission wheel body;
One is installed in the external conical shape sleeve of internal taper hole, have one in the cone smaller diameter end of sleeve and outward extendingly have an externally threaded cylindrical duct, the internal diameter of cylindrical duct is identical with the internal diameter of sleeve, the cone gradient of sleeve and the internal taper hole gradient of drive wheel adapt, the internal diameter of each point equates on the sleeve, sleeve diameter has an elongated opening along its whole axial length greater than the diameter of transmission shaft on the sleeve;
Be installed at least one packing ring and at least one nut on the outside thread cylindrical duct of conical sleeve.
Further solution of the present utility model is:
The gradient of internal taper hole and sleeve cone is 1: 2-1: 50, be preferably 1: 10;
The internal diameter of sleeve is greater than the diameter 0.05-1.00 millimeter of transmission shaft;
The width of the elongated opening on the sleeve is the 1-10% of transmission shaft diameter;
Outside thread cylindrical duct on the sleeve and the cone on the sleeve are integral pieces made from commaterial;
The external diameter of the outside thread cylindrical duct on the sleeve is less than the less internal taper hole diameter on the less internal taper hole end face of drive wheel;
The distance of the end face of the cone smaller diameter end face of sleeve and the less internal taper hole diameter of drive wheel is the 5-15 millimeter.
The utlity model has convenient disassembly, and to equipment and the undamaged characteristics of parts.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a longitudinal section of the present utility model.
Fig. 2 is the side view of Fig. 1.
On the wheel body of drive wheel 1, have an internal taper hole 2.One conical sleeve 3 with one section outside thread cylindrical duct is installed between internal taper hole 2 and the transmission shaft (not drawing among the figure), the cone gradient of sleeve 3 is identical with the gradient of internal taper hole 2, its gradient scope is 1: 2-1: 50, be preferably 1: 10, the internal diameter of each point equates on the sleeve 3, and promptly sleeve inner is a straight barrel.The internal diameter of sleeve is greater than the diameter 0.05-1.00 millimeter of transmission shaft.
On sleeve 3, have an elongated opening 4 along its whole axial length, the width of opening 4 is the 1-10% of the diameter of axle, and at least one packing ring 6 that adapts with the major diameter of thread of outside thread cylindrical duct and the nut 7 that at least one matches are installed on the outside thread cylindrical duct 5.The internal diameter minimum of packing ring 6 should be identical to the circle diameter at 15 millimeters places along cone axis with the cone smaller diameter end face 8 of sleeve 3.The thickness of packing ring 6 is the 5-20 millimeter, is preferably 10 millimeters, and the cone top diameter end face 8 on the sleeve 3 is the 5-15 millimeter with the distance of the top diameter end face 9 of the internal taper hole 2 of transmission wheel body 1, is preferably 10 millimeters.The major diameter of thread of the outside thread cylindrical duct 5 on the sleeve 3 is less than the less internal taper hole diameter of the less internal taper hole end face of the internal taper hole 2 of drive wheel 1.
Assembly process of the present utility model is, an end of the outside thread cylindrical duct 5 on the sleeve 3 end face 10 from the big internal taper hole diameter of the internal taper hole 2 of drive wheel 1 is inserted, and stretches from the end face 9 of the less internal taper hole diameter of internal taper hole 2.Packing ring 6 is enclosed within on the outside thread cylindrical duct 5, simultaneously nut 7 is screwed on the outside thread cylindrical duct 5, be loose coupled situation.At this moment, the integral body that drive wheel 1, sleeve 3, packing ring 6 and nut 7 is coupled to is inserted on the transmission shaft.Fastening nut 7 firmly, nut 7 is drawn in sleeve 3 between internal taper hole 2 and the transmission shaft, nut 7 is pressed drive wheel 1 inwards by packing ring 6 and sleeve 3 in other words, internal taper hole 2 produces slide relative with respect to sleeve 3, the size of the elongated opening 4 on the sleeve 3 is dwindled, transmission shaft is held tightly, thereby realized the fixing of drive wheel and transmission shaft.When dismounting, unclamp nut 7 earlier, at this moment, the size of the elongated opening 4 on the sleeve 3 enlarges, and the straight barrel internal surface of sleeve 3 and transmission shaft outer surface form the gap.At this moment, the integral body that drive wheel 1, sleeve 3, packing ring 6 and nut 7 are formed can be removed from transmission shaft.
Drive wheel of the present utility model can be a flat pulley, and Vee pulley V etc. are powered drive wheel similarly.In the utility model scope of disclosure, those of ordinary skill in the art can make many variations.
