Description

A device for producing herringbone synchronous belt

Technical field:

The utility model relates to a device for producing a herringbone synchronous belt, in particular to a device for producing a herringbone synchronous belt.

Background technique:

The production process of the synchronous belt is to extrude the rubber into the tooth groove of the mold through vulcanization and high pressure to form the rubber tube of the synchronous belt. The inside of the rubber tube is the belt tooth, and the tooth direction of the belt tooth is parallel to the axial direction of the mold Insert it into the grooves on the outer surface of the mold, and then use the demoulding mechanism to move the rubber tube along the axial direction of the mold and demould it. This process is suitable for the production of straight-toothed synchronous belts. For herringbone-toothed synchronous belts, the tooth direction of the belt forms a certain angle with the axial direction of the mold, and the existing process cannot be used for demoulding. Therefore, it is very necessary to design a detachable combined herringbone synchronous belt production device to solve the problems in the manufacture of herringbone synchronous belts.

Utility model content:

The purpose of this utility model is to provide a device for producing herringbone synchronous belts, which can produce multiple synchronous belts at the same time. After the equipment is cut into a herringbone timing belt with a specified width, the demoulding of the herringbone timing belt can be realized by disassembling the detachable combined production device.

The purpose of this utility model is achieved in the following manner: the device for producing herringbone tooth synchronous belts adopts a technical solution that includes an end cover, a left-handed gear, a right-handed gear and a support seat, the left-handed gear The ring and the right-handed ring gear are sleeved on the support seat. A left-handed ring gear and a right-handed ring gear are axially connected by pins to form a group. Each group is separated by a gasket. The left-handed ring gear and the right-handed ring gear The surface is evenly distributed with tooth-shaped grooves, and the tooth-shaped grooves on each set of left-handed and right-handed ring gears form a herringbone shape, and the two sides of the support seat are provided with end covers. the

Preferably, a washer is provided between the end cap and the left-handed ring gear or the right-handed ring gear. the

Preferably, grooves are provided on adjacent sides of each pair of left-handed ring gears and right-handed ring gears. the

The beneficial effects of the utility model are: the device for producing herringbone synchronous belts can produce multiple synchronous belts at the same time, and the relative positions between left and right spiral teeth on the synchronous belts are positioned by pins. Its structure design is reasonable, the assembly and disassembly operation is convenient and fast, and it is suitable for the manufacture of herringbone tooth timing belts. the

Detailed ways:

Referring to Figure 1, the device for producing herringbone synchronous belts is characterized in that it includes an end cover 1, a left-handed ring gear 3, a right-handed ring gear 4 and a support seat 8, and the left-handed ring gear 3 and right-handed gear The ring 4 is set on the support seat 8, and a left-handed ring gear 3 and a right-handed ring gear 4 are axially connected by pins 6 to form a group. The relative positions between the left and right-handed teeth on the timing belt are positioned by the pins 6. The groups are separated by spacers 5, and the surfaces of the left-handed ring gear 3 and the right-handed ring gear 4 are evenly distributed with tooth-shaped grooves, and the profile of the tooth-shaped grooves is the same as that of the teeth on the synchronous belt to be processed. The tooth-shaped grooves on each group of left-handed ring gear 3 and right-handed ring gear 4 form a herringbone shape, and end covers 1 are provided on both sides of the support seat 8 . A washer 2 is provided between the end cover 1 and the left-handed ring gear 3 or the right-handed ring gear 4 . Each pair of left-handed ring gears 3 and right-handed ring gears 4 is provided with grooves 7 on the adjacent side, so as to facilitate removal of the left-handed ring gears 3 and right-handed ring gears 4 .
