Problems solved by technology
[0002] In machinery manufacturing, gear mechanisms are commonly used in military and civilian products. The processing of gears involves the calculation of the configuration of the hanging gear. At present, there are two main methods for the configuration of the hanging gear: one is manual calculation with a calculator , its shortcomings are that the method is primitive and the speed is relatively slow; the second is to check the configuration manual of the hanging wheel, the existing problems are more troublesome and less accurate
It takes a lot of time to manually perform tens of millions of configuration combinations, which is basically unrealistic. As a result, the transmission ratio and configuration accuracy of the hanging wheel configuration are often not the best solution.

Embodiment Construction
[0022] Such as figure 1 As shown, a method for configuring the hanging gear of a gear processing machine tool includes the following steps:
[0023] 1) Create a database on the computer, which is used to record the number of teeth of the four hanging gears that meet the configuration requirements, the theoretical gear ratio i and the combined gear ratio Z Z , the theoretical transmission ratio i of the hanging gear is calculated according to the following formula:
[0024] i=(3.5×sin(δ)×Z i ) / (cos(θ f ) x Z)
[0025] where Z i is the number of spanning teeth, δ is the pitch angle, θ f is the dedendum angle, and Z is the number of teeth of the gear.
[0026] 2) Create a calculation interface for gear machining machine tool gear configuration, which includes a result display box, a theoretical gear ratio input box, a gear minimum number of teeth input box, a gear maximum teeth number input box, and a gear ratio accuracy input box for gear set configuration. and Calculate ...

The invention discloses a configuration method for gear cutting machine change gears. The configuration method for the gear cutting machine change gears comprises the following steps that (1), a database is established in a computer; (2), a calculating interface for gear cutting machine change gear configuration is established; (3), theoretical change gear transmission ratio value i is set; (4), the change gear group configuration transmission ratio precision ZJD is set; (5), the theoretical change gear transmission ratio value i, the change gear group configuration transmission ratio precision ZJD and the range, from the minimum tooth number ZMIN to the maximum tooth number ZMAX, of the configured gears are input; (6), the tooth numbers of the four change gears are sequentially configuredin a permutation and combination manner; (7), when an error between combined change gear transmission ratio value ZZ of the group and the set theoretical change gear transmission ratio value i is notlarger than the set change gear group configuration transmission ratio precision ZJD, the data are stored in the database till the tooth numbers of the four change gears are all configured and combined within the range from the minimum tooth number ZMIN to the maximum tooth number ZMAX; and (8), the stored data are displayed in the calculating interface for gear cutting machine change gear configuration.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for configuring hanging wheels of a gear processing machine tool. Background technique [0002] In machinery manufacturing, gear mechanisms are commonly used in military and civilian products. The processing of gears involves the calculation of the configuration of the hanging gear. At present, there are two main methods for the configuration of the hanging gear: one is manual calculation with a calculator , its shortcoming is that the method is primitive and the speed is relatively slow; the second is to check the configuration manual of the hanging wheel, and the existing problems are troublesome and poor in accuracy. It takes a lot of time to manually perform tens of millions of configuration combinations, which is basically unrealistic. As a result, the current transmission ratio and configuration accuracy of the hanging wheel configuration often fail to reach th...
