Technical Field

The invention relates to the technical field of speed regulators, in particular to a noiseless direct-connection speed regulator.

Background

In mechanical equipment design, especially packaging machinery, a structure that two roller bodies rotate in the same direction or opposite directions is often used, and particularly a rotating structure requiring quantitative differential speed or mechanical synchronization is required. Because the distance between the two roller bodies is usually narrow in the structure, a common designer can connect the two roller bodies in a chain or belt mode through two speed regulating mechanical assemblies. In the general speed-regulating mechanical market (including a speed reducer or an accelerator), the speed-regulating mechanical market is a single-stage input and output product, and a single-stage input and two-stage output product is not available.

As shown in fig. 1, the single-stage motor input (single-stage manual input), the two-stage output turbine speed reduction mechanism and the external coupling mechanism are adopted, and the mechanism is applied to the opposite transmission of a glue homogenizing roller and a transfer steel roller of a five-roller solvent-free coating compound machine, and has the following defects: 1. the distance between the roller bodies is narrow, so that a plurality of structures cannot be used; 2. the two speed regulating mechanical assemblies are additionally provided with an external connecting mechanism, so that the cost is high; 3. the external coupling mechanism needs frequent maintenance and is easy to generate oil stains; 4. the external connecting mechanism has strength requirement and is easy to generate abnormal movement sound; 5. various structures are combined, the assembly is difficult, the operation is inconvenient, the cost is high, and the method is not suitable for large-scale popularization.

The patent number is CN 201921292031.3's a five roller coating transmission, for this company in a utility model patent of 2019 application, this patent has been granted at present, discloses the coaxial setting of input shaft and the input shaft of second speed regulator of first speed regulator, and the one end that the second speed regulator was kept away from to the input shaft of first speed regulator is connected with driving motor, and the other end of the input shaft of first speed regulator passes through switching device and is fixed with the input shaft of second speed regulator. The patent reduces the problem of noise to a certain extent, but because the input shafts of the two speed regulators are connected and fixed through the input shafts, certain noise still exists between the input shafts, and the equipment cost is high. Based on the above problems, the present application is further optimized for cost, transmission abnormal sound, assembly difficulty and daily maintenance.
