Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 3, the wheel puller using the clasping chain for the wheel puller of the present invention comprises a main frame body 1, wherein the main frame body 1 is provided with two cantilever arms 11 which are oppositely and outwardly suspended. The central point of the main frame body 1 is provided with a nut which is matched with the thread on the mandril 2, the cantilever 11 is provided with a through groove 12 which runs through the upper side and the lower side of the cantilever 11, and the width of the through groove 12 is matched with the diameter of the pull rod 3, so that the pull rod 3 can move in the through groove 12. The pull rod 3 is a long screw rod with a hexagonal head at the upper end, the hexagonal head of the pull rod 3 is blocked on the upper side surface of the groove wall of the through groove 12, and a gasket is arranged at the head of the pull rod 3, so that the pull rod 3 and the groove wall of the through groove are stressed uniformly.
The pulley extractor also comprises a holding mechanism connected to the lower end of the pull rod, the holding mechanism comprises a holding chain 4 consisting of a plurality of chain links 41 and used for holding the belt pulley circumferentially, and the chain links 41 are provided with V-shaped protrusions matched with the shape of a single belt groove. One end of the chain link 41 is provided with a cylindrical convex column 44, the cylindrical convex column 44 is suspended and extended towards the length direction of the chain body, so that the connection part of the cylindrical convex column and the chain link is only pulled when the tightly-holding chain tightly-holding belt pulley, the strength is increased, the axis of the cylindrical convex column 44 is parallel to the axis of the tightly-holding chain 4, the other end of the chain link 41, which is opposite to the cylindrical convex column, is provided with a groove matched with the cylindrical convex column 44, and the cylindrical convex column 44 can rotate in the groove. Each chain link is hinged and matched with the groove through the cylindrical convex column and is connected end to form a chain body of the clasping chain. The head and the tail of the clasping chain 4 are provided with connectors, the connectors are provided with connecting plates 43 extending outwards along the radial direction of the clasping chain, and the two connecting plates 43 are connected through bolts. The outer side faces of the two chain links 41 at two ends of the diameter on the clasping chain 4 are provided with radially outward protruding lugs, the lugs are provided with connecting holes used for being connected with the pull rod, the connecting holes are waist-shaped holes 42 extending along the circumferential direction of the clasping chain, the width of each waist-shaped hole 42 is matched with the diameter of the pull rod 3, and the pull rod 3 can move and adjust along the length direction of each waist-shaped hole. The length of the slotted hole 42 is greater than or equal to the length of one chain link, so that the adjustment range of the pull rod is enlarged.
When the wheel puller is used, the quantity of chain links in the tight chain is held in the adjustment earlier, make the length of holding the chain and the big or small adaptation of belt pulley, then will hold the chain lock tightly in the race of belt pulley, through the bolt on the connector of fastening the chain of holding tightly, make and hold the chain tightly in the race, then connect the pull rod on holding the chain simultaneously with the head of ejector pin support on the tip of shaft, if the position of pull rod is improper, just adjust the pull rod and remove in the logical groove of cantilever and the waist shape hole on holding the chain, can extract the belt pulley through the rotatory ejector pin of spanner at last. This pull out trochus just can make through the chain link number of adjusting the chain of embracing tightly and embrace the belt pulley that the chain adapts to different diameters tightly, has avoided being equipped with the problem that the mechanism of embracing tightly that a plurality of different specifications caused the cost height of pull out trochus. As shown in figure 3, when the pulley extractor is used, two rows of clasping chains can be adopted, and a force transmission piece is arranged between the two rows of clasping chains, so that the matching area between the clasping mechanism and the belt pulley is increased, and the pulley extractor is particularly suitable for belt pulleys with larger diameters.
As shown in fig. 4, a specific embodiment 2 of the pulley for a pulley puller of the present invention is different from embodiment 1 in that three waist-shaped holes are formed in a chain body of a clasping chain for a pulley puller in this embodiment, a main frame body of the pulley puller adapted to the chain body is provided with three cantilevers 21 radially distributed, the three cantilevers 21 are distributed at intervals of 120 °, and a pull rod is connected between the cantilevers and the clasping chain, so that stress points on the clasping chain are increased, which is more favorable for balancing stress of the pulley, and prevents the pulley from being locked due to deflection when being pulled out, and the others are the same as those in embodiment 1 and are not described again.
The chain link in the clasping chain in the embodiment 3 of the wheel extractor of the invention is shown in fig. 5, and is different from the embodiment 1 in that the cylindrical convex column 244 on the chain link in the embodiment extends along the radial direction of the clasping chain, and correspondingly, the opening of the groove at the other end of the chain link faces the radial direction of the clasping chain.
In other embodiments of the present invention, the number of the waist-shaped holes on the clasping chain for connecting with the pull rod may also be two, four, five or other numbers, and when the number of the waist-shaped holes is other numbers, the waist-shaped holes are preferably uniformly distributed on the clasping chain, so that the clasping chain is stressed in balance when in use; the connecting holes can also be round holes, and a plurality of connecting holes can be arranged on the chain link at the moment, so that the position of the pull rod on the holding chain can be adjusted; the chain link can also be provided with two rows of V-shaped bulges, so that the clasping chain can be directly matched with the double-groove belt pulley, and the quantity of the V-shaped bulges can also be other quantities.
