DRIVE UNITS
Motors are used to drive the actuator. In most cases, a transmission mechanism is installed between the motor and the actuator, which converts the original rotary motion of the motor into a slower motion of the performer. As transmission mechanisms, single- or multi-stage gearboxes are used in combination with belt and chain drives, gearboxes, etc. The gearbox, as a rule, contains gears, shafts and rolling bearings installed in the housing. The APM Drive module is designed for complex calculation and execution of design documentation for all elements of a multistage drive.
Creation of drive design documentation
The work of APM Drive is completed by transferring the calculated information to a text file with the RTF extension and automatically generating an assembly drawing of the drive and drawings of individual parts of the designed elements in the APM Graph module. The resulting drawing must be considered as a blank in the sense that it is supposed to be further refined manually in the APM Graph module. As a result, you can get an assembly drawing of the drive and drawings of the parts included in it.
Drive design
The parameters of each of the elements of the kinematic chain, adopted according to the results of the design calculation, can be edited to obtain more rational drive characteristics. In this case, it is assumed that the drive itself is made according to an expanded layout scheme, when all shafts are placed in the same plane.
For planetary gears, in addition to the usual strength calculations, the number of teeth is selected taking into account the fulfillment of the conditions of neighborhood, alignment and assembly.
When checking the calculation for a given geometry, you can calculate the output characteristics for an arbitrary placement of the shaft axes in space.

Purpose of APM Drive
The process of designing a rotary motion drive of arbitrary structure using the APM Drive module is reduced to setting a kinematic scheme in a special editor, entering the initial and final parameters of the drive as a whole, as well as analyzing and correcting the results. This module works in conjunction with the APM Trans Gear, APM Shaft, and APM Bear Roller Bearings modules, so that all the design characteristics that these modules provide can be output.
Additionally, the APM MechanicalData database is used for calculations, and the APM Graph graphical editor is used to obtain the drawings of the designed drive elements generated by the corresponding modules.

The editor of the task of the kinematic scheme of the transmission mechanism
The editor is designed to create a kinematic diagram of the drive. The number of gear stages can be quite large.
The drive may include gears and bearings of the following types:
- transfers;
- cylindrical spur, helical and chevron involute profile;
- conical with a straight and circular tooth;
- worm gear of various types;
- planetary most common types.
- rolling bearings
- ball radial;
- ball double-row spherical;
- ball radial-thrust and thrust-radial;
- ball thrust;
- roller radial and needle;
- roller two-row spherical;
- roller radial-thrust and thrust-radial;
- roller thrust.
Of the many types of gears, shafts and bearings, you can assemble a drive of arbitrary structure to transfer rotation from the engine to the actuator. At the same time, the APM Drive module will automatically determine the geometric dimensions of gears and shafts, as well as select rolling bearings from the database.

Drive design
According to the given kinematic scheme of the drive, the kinematic and power parameters (gear ratio, torque and speed) are divided into steps in automatic and interactive modes.
In addition, in the process of preparing for the calculation, you must specify:
- drive loading mode (constant or variable);
- heat treatment of gear material;
- shaft materials.
The results of the design calculation are:
- gear parameters (such as geometric dimensions, meshing forces, tool parameters for cutting and inspection, etc.);
- shaft designs and dimensions;
- geometric dimensions of rolling bearings selected from the database.
The parameters of each of the elements of the kinematic chain, adopted according to the results of the design calculation, can be edited to obtain more rational drive characteristics. In this case, it is assumed that the drive itself is made according to an expanded layout scheme, when all shafts are placed in the same plane.
