In the recent cooperation with manufacturers, we discovered a problem.

A machinery factory, they reimbursing, to design and will be put into a set of production equipment, in this device, the past is the chain drive transmission effect.

But is the promotion of the equipment, insulation, therefore require synchronous belt transmission device, the designers also is first contact, and is not very good, to quote a few models.

There is no this several models, no one can make, because of their model is wrong.

To contact our engineers, communication down, by adjusting the center distance, they only finished.

So, here, to the designer and friends with learn to synchronous belt and synchronous belt wheel calculation method.

Synchronous belt wheel product use:

Synchronous belt wheel can be allowed to work in pollution and environmental work is bad situation. Widely used in automobile, textile, printing and packaging

Prepare, sewing equipment, office equipment, laser engraving equipment, tobacco, financial tools, stage lighting, communications, food machinery, medical machinery, steel

Iron machinery, petrochemical industry, instruments and meters, all kinds of precision machine tools, etc.

Synchronous belt transmission design.

A. meshing gear synchronous belt and small pulleys of meshing teeth should be 6 or more, if allowed, by increasing the center distance, or pulley diameter stays the same

Adverse circumstances, the use of fine-pitch, but should be under the condition of the force to allow.

B. synchronous belt width and pitch and pitch line length due to the determination of synchronous belt width, the calculation formula is complex, so often used in practical design

Calculating the circumferential force, and with reference to allowable twisting force in the mechanical design manual, finds out the corresponding bandwidth and pitch, generally take 5.08. In determining the section

Distance and bandwidth, according to the initial center distance calculation with pitch line length, and then according to the standard option, if does not conform to, can adjust center distance.

C. computer flat knitting machine head driving mechanism of circular arc form is generally selected tooth synchronous belt, also some choose trapezoidal, but no matter what kind of tooth shape all want to meet

Belt wheel, which is a circle, and the section of line tangent, and implements the pure roll, the second is on the pulley between two corresponding points on the circular arc tooth distance equal to

Step with pitch. In order to ensure the good performance of mesh belt and belt wheel in the design, should be properly selected belt wheel gear tooth profile Angle, according to Japanese hill rich husband

Such as test and our factory found in the actual development process, when the tooth profile Angle of 20 ° ~ 25 °, tooth and tooth interference quantity is small, and the tooth profile Angle deviation

Difference of plus or minus 1 °.
