Abstract
The invention discloses a transmission belt. The transmission belt comprises a belt body. The transmission belt is characterized in that the belt body is cylindrical; and the belt body is integrally cast and molded through compression, and no connection marks exist in the whole body; a reinforcing rib is arranged on a core portion of the belt body and inlaid into the core portion of the belt body; and the reinforcing rib and the belt body are synchronously molded through casting. A structural mode that a steel wire and polyurethane are tightly laminated is adopted, and through vacuum molding, the transmission belt is tight in structure, the steel wire can play a role in reinforcing better, and the mechanical strength of the transmission belt is ensured. The transmission belt is easy and convenient to produce and machine, simple in structure, good in mechanical performance and long in service life.
Description
Technical field
The present invention relates to a kind of industrial belt, especially a kind of driving belt and production technology thereof.
Background technique
Polyurethane PU Timing Belt is made up of thermo-plastic polyurethane's material, has comparatively high resistance against wear ability, and all kinds wire-core ensures that it still keeps good locomitivity in transmission, and production tolerance is little.In production process, at the flank of tooth and/or the back of tooth, in addition one deck nylon is constant to ensure the operation particularity in special applications, also can thicken one deck polyurethane to prevent corrosion or high capacity in belt back.
At present, the driving belt ubiquity strength deficiency on market, the problem that serviceability is not high, time its reason is mainly cast, between feed liquid and reinforced wire in conjunction with defective tightness, cause that driving belt elongates in transmission running, the fault such as fracture.
Summary of the invention
The object of this invention is to provide a kind of laser intensity high, the driving belt of good mechanical property and production technology thereof.
For achieving the above object, the technical solution adopted in the present invention is: a kind of driving belt, comprises belt body, it is characterized in that: described belt body is for cylindric, and belt body is integrated poured compression molding, overall without connecting vestige; Be provided with reinforcement bone at the core of belt body, described reinforcement bone is embedded in belt body core, moulding by casting synchronous with belt body.
Preferably, described belt materials is polyurethane.
Preferably, described reinforcement bone is steel wire.
Preferably, described belt body is Timing Belt.
A production technology for driving belt, is characterized in that: comprise the following steps:
A. to stir polyurethane master batch and look female in the ratio of 10:1 and heating and melting becomes aqueous;
B. according to model and the size needs of driving belt, determine casting mold, and steel wire is added be placed in mould specified position on fix intact;
C. will be melt into aqueous cast polyurethane in mould, and carry out vacuum molding its polyurethane and steel wire are closely merged.
D. the demoulding process periphery overlap feed liquid after driving belt cooling forming, completes the cast of driving belt.
Preferably, the pressure of the vacuum molding described in step C is 800Kg.
The present invention is by adopting the structural type of steel wire and the tight pressing of polyurethane, and make drive belt configuration tight by vacuum molding, steel wire can play stiffening effect better, ensures the mechanical strength of driving belt.Production and processing of the present invention is easy, and structure is simple, good mechanical property, long service life.
Embodiment
A kind of driving belt, comprises belt body, it is characterized in that: described belt body is for cylindric, and belt body is integrated poured compression molding, overall without connecting vestige; Be provided with reinforcement bone at the core of belt body, described reinforcement bone is embedded in belt body core, moulding by casting synchronous with belt body.
Preferably, described belt materials is polyurethane.
Preferably, described reinforcement bone is steel wire.
Preferably, described belt body is Timing Belt.
A production technology for driving belt, is characterized in that: comprise the following steps:
