Problems solved by technology

Cut out the required belt length in advance, and then cut out the joints at both ends of the belt, that is, punch the two sides of the synchronous belt into convex and concave pairs of teeth, and after matching them, heat the joints at high temperature to fuse them into a ring Overall, but the skeleton rope that plays the role of skeleton in the synchronous belt is still in a disconnected state, so that the tensile strength of the seam is the smallest, leaving a quality hidden danger, which is easy to break here during use, reducing the safety of the synchronous belt. service life
[0004] Spliced ​​timing belts are prone to breakage at the seams under high loads
In addition, connecting the synchronous belt is also prone to improper cutting length and mismatched teeth, resulting in unnecessary waste, which not only affects the transmission efficiency, but also increases the manufacturing cost

Embodiment 1

[0038] Embodiment 1: as figure 2 As shown, according to the required length of the belt body 1 of the synchronous belt, the center distance of the skeleton rope 4 contained in the belt body 1 is calculated, the fixing frame 7 is installed on the base 11, and the fixing roller 9 is installed on the fixing frame 7. The movable frame 8 can be displaced left and right along the base 11 to ensure the size of the center distance. The movable frame 8 is equipped with movable rollers 10 . The wire winding machine winds the skeleton rope 4 evenly around figure 2 The skeleton rope shown is positioned on the tooling 25 . A uniform gap is reserved between each skeleton rope 4, with a width of 30mm, and the total width of the skeleton rope 4 arrangement is 500mm; the cutting process interval is reserved for 5mm.

[0039] The skeleton ropes 4 arranged on the positioning tool are poured into the open tooth mold 26, and the initial tension of the arranged skeleton ropes 4 is adjusted s...

Abstract

The invention belongs to the technical field of synchronous belt production and processing, and particularly relates to a super-long seamless polyurethane synchronous belt, and production equipment and a preparation method thereof. The invention provides the super-long seamless polyurethane synchronous belt, and the production equipment and the preparation method thereof. The super-long seamless polyurethane synchronous belt provided by the invention comprises a belt body, and is characterized in that the belt body is annular; the belt body and a skeleton rope in the belt body do not have a seam.

Description

technical field [0001] The invention belongs to the technical field of synchronous belt production and processing, and in particular relates to an ultra-long seamless polyurethane synchronous belt, production equipment and a preparation method thereof. Background technique [0002] The traditional seamless polyurethane synchronous belt is produced by manual centrifugal casting, using circular convex and concave molds for positioning, and pouring the pre-prepared polyurethane solution into the mold cavity. After pouring is complete, the mold is transferred to an oven for curing. When the specified time is reached, the mold is opened, the flash is trimmed, and the shape is cut. The maximum circumference of the synchronous belt processed by this method is not more than 4000mm, otherwise the mold and manufacturing process are limited and it is difficult to produce, and one mold can only produce synchronous belts of one length and tooth type, the manufacturing cost is expensive,...
