Specific embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment 1 of the pulley extractor of the present invention, as shown in Figure 1 to Figure 3, pulley extractor includes main frame body 1, main frame body 1
With two cantilevers 11 for overhanging out against.The center position of main frame body 1 is provided with the spiral shell coordinated with the screw thread on push rod 2
Mother, cantilever 11 is provided with the groove 12 of the upper and lower side through cantilever 11, and the width of groove 12 is adapted to the diameter of pull bar 3, with
Pull bar 3 is set to move in groove 12.Pull bar 3 is the long bolt that upper end has six square toes, and six square toes blocks of pull bar 3 are logical
On the upper side of the cell wall of groove 12, and the head of pull bar 3 is provided with pad, so that stress between pull bar 3 and the cell wall of groove
Uniformly.
Pulley extractor also includes being connected to the hold-fast body of pull bar lower end, and hold-fast body is included by embracing that multiple chain links 41 are constituted
Tight chain 4, has raised with the V-arrangement of the shape adaptation of belt grooves on chain link 41.One end of chain link 41 is provided with cylindrical projection 44, circle
Cylindricality projection 44 along hold tightly chain circumferencial direction stretch out, so when hold tightly chain hold tightly belt pulley make cylindrical projection with
Pulling force, intensity increase, the axis of cylindrical projection 44 and the diameter parallel for holding chain 4 tightly are only received in the junction of chain link, chain link 41
The other end relative with cylindrical projection is provided with the groove coordinated with cylindrical projection 44, and cylindrical projection 44 can be in a groove
Rotate.Each chain link is hinged cooperation and joins end to end by circular cylindrical projection post and groove, constitutes the serobila for holding chain tightly.Hold chain 4 tightly
Head and the tail two ends are equipped with connector, and connector is respectively provided with the connecting plate 43 extended radially outwardly along holding chain, two connecting plates 43
It is bolted.Hold tightly and be provided with the lateral surface of two chain links 41 at the two ends of diameter on chain 4 project radially outward convex
Block, the projection is provided with the mounting hole 42 extended along the circumferencial direction for holding chain tightly, the width of mounting hole 42 and the diameter of pull bar 3
Adaptation is so that pull bar 3 can move adjustment along the length direction of mounting hole.The length of mounting hole 42 is more than or equal to one
The length of chain link, so increases the adjusting range of pull bar.
When the pulley extractor of the present invention is used, the quantity of chain link in chain is held in first adjustment tightly, makes the length and belt pulley of holding chain
Size adaptation, then by hold tightly chain be buckled in the race of belt pulley, by fastening hold tightly chain connector on bolt, make embrace
Tight chain is tightly held tightly in belt grooves, is then connected to pull bar and holds tightly on chain while the head of push rod to be against the end of wheel shaft
In portion, if the position of pull bar is improper, just adjustment pull bar is moved in the groove of cantilever and in the mounting hole on chain is held tightly,
Belt pulley can be extracted finally by spanner rotation push rod.The pulley extractor just can be made by the chain link quantity that chain is held in adjustment tightly
Hold the belt pulley that chain adapts to different-diameter tightly, it is to avoid the hold-fast body of outfit multiple different sizes causes the high cost of pulley extractor
Problem.As shown in figure 3, pulley extractor can also hold chain tightly when using using two rows, now this two row holds tightly and be provided between chain
Force transmission element, which increases the cooperation area between hold-fast body and belt pulley, is particularly suited for the belt pulley being relatively large in diameter.
The specific embodiment 2 of the pulley extractor of the present invention, as shown in figure 4, being the present embodiment with the difference of embodiment 1
In the main frame body of pulley extractor there are three cantilevers 21 being radially distributed, and three cantilevers 21 are spaced 120 ° of distributions, phase
Answer, pull bar and the quantity for holding the mounting hole on chain tightly are also three, which increase the stress point held tightly on chain, more favorably
In making belt pulley stress equalization, it is to avoid belt pulley occurs beat and stuck when extracted, and other are same as Example 1, no longer go to live in the household of one's in-laws on getting married
State.
In the specific embodiment 3 of the pulley extractor of the present invention chain is held tightly as shown in figure 5, existing with the difference of embodiment 1
The two ends of the chain link 241 of the holding chain in the present embodiment are provided with the otic placode that two relative spacings are arranged, and two otic placodes are provided with
Hinge hole 242, by a connecting plate connection between two adjacent chain links, drawing is eliminated between each connecting plate and chain link
Jointed shaft, other are same as Example 1, repeat no more.
The chain link held tightly in chain in the specific embodiment 4 of the pulley extractor of the present invention is as shown in fig. 6, with embodiment 1 not
With part be cylindrical projection 244 on the chain link in the present embodiment be to extend along the radial direction for holding chain tightly, accordingly
, also direction holds chain tightly in the radial direction to the opening of the groove of the chain link other end.
In other embodiments of the invention, the quantity of the cantilever on main frame body can also be four, five, six or
Other quantity, now each cantilever be radially uniformly distributed；There can also be the V-arrangement of two rows raised on chain link, so hold tightly
Chain just can directly be adapted to two-groove belt pulley, and certainly, the raised quantity of V-arrangement can also be other quantity.
