[Prior Art] Conventionally, a gear motor has been known which has a motor having a motor shaft provided with a screw pin at a front end thereof, and a helical gear for engaging with the screw pinion and for inputting The speed reducer of the speed reduction mechanism that is decelerated by the rotation of the helical gear is detachably coupled to the motor side joint portion provided in the motor and the speed reducer side joint portion provided in the speed reducer (for example, refer to the patent literature) 1 ). Such a geared motor unit is provided with a plurality of types having different output capacities, so that a design corresponding to the appropriate output of the application can be selected. Specifically, the motor of the plural type in which the output capacity (maximum utilization rate, maximum torque, and the like) is different is combined with the output capacity of the respective motors to have appropriate mechanical strength (gear strength, shaft). The multiple types of reducers for strength, casing strength, etc.). Further, in general, the speed reducer is prepared with a plurality of reduction ratios for each mechanical strength. By integrating a plurality of types of gear motors having different output capacities, there is an appropriate output capacity corresponding to the application, and the output capacity is made to be a gear motor that can be easily selected to be small and low-cost. However, even if the required output capacity is the same 'in practice, there is a variation in the life of the gear motor due to the use. For this reason, the output of the -4-(2) 1278166 output is common, and the mechanical strength of the helical pinion or the reducer set on the motor shaft is different, for example, the standard type and the reinforced type are set. A variety of geared motors, and corresponding to the ever-changing needs. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-240 No. 05-A SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] # However, two types of gears such as a standard type and a reinforced type are set for each output capacity. When the electric motor is used as a unit of the gear motor, the number of parts increases, resulting in a large cost increase. In addition, there is a difference in the life of the motor and the life of the reducer, and the gear motor of each of the output capacities, such as the standard type and the reinforced type, is set to have a demand for a market that cannot meet ever-changing needs. Case. The present invention has been developed in view of the above problems, and the problem is to construct a gear motor unit that can provide a gear motor that can suppress an increase in the number of parts and meet the needs of an ever-changing market. The present invention relates to a motor having a motor shaft integrally formed with a helical pinion, and a reduction gear having a helical gear for engaging with the helical pinion, and detachably coupled to the motor a motor-side coupling portion of the motor and a gear set in the gear--5-(3) 1278166-wheel motor of the reduction gear side coupling portion of the reduction gear, and the motor is prepared in a plurality of types having different output capacities, and the plurality of types At least two types of electric motors are common to the motor-side joint portion and the tooth shape of the spiral pinion, and the speed reducer is a plurality of types having different mechanical strengths, and the plurality of types are At least two types of reducers among the reducers, the above-mentioned reducer side joints The various elements of the tooth shape of the helical gear are common, and the combination of any of the at least two types of electric machines and the at least two types of speed reducers can be combined to transmit power. Subject. The unit of the geared motor is capable of combining a variety of motors with different output capacities and a combination of various types of speed reducers with different mechanical strengths. Therefore, it is possible to provide a combination of various output capacities as needed. The gear motor of the electric motor and various types of mechanical strength reducers. For example, the required output capacity is in the use of P 1 , and the reducer can provide a motor with combined output capacity p1 and relative to the output when it is required to have a greater mechanical strength than the basic requirements of its use. The gearbox motor of the reducer having a larger mechanical strength S2 than the gearbox of the mechanical strength S1 which is generally applicable. Therefore, when the gear motor of various output capacities is set to a plurality of types of the standard type and the reinforced type, it is possible to suppress an increase in the number of parts of the entire unit of the gear motor and increase the diversity at a low cost without increasing the number of parts. Market needs. According to the present invention described above, the motor of the predetermined output capacity is not a speed reducer which is generally applicable to the mechanical strength of the output capacity, and the -6 - (4) 1278166 stomach composition can generally be in terms of its output capacity. The gear motor unit combined with the mechanical strength of too large or too small / reducer can not only inhibit the increase of the total number of parts of the gear motor unit, but also meet the needs of the market diversity' compared to the preparation of various motors. A conventional gear motor unit of a geared motor that can be combined with a reduction gearbox' and has a small output capacity is constructed according to a completely different concept.
