クト化をも可能とする減速機用のケースに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to reduce the number of members, improve productivity, and make the apparatus compact by using a common output case in a series of speed reducers having different speed ratios. Regarding a case for a speed reducer.

せるいわゆる減速機がある。2. Description of the Related Art Speed reducers are used in series, in which a plurality of types of speed ratios are standardized for each kw and made into a series to prepare in advance. Note that the speed reducer includes a speed reducer motor in which an electric motor is integrated in advance and a motor shaft is used as an input shaft of the speed reducer, that is, a gear motor and a so-called speed reducer in which the input shaft of the speed reducer is projected.

ーズにおいては、実質的に不可能である。On the other hand, when standardizing the reduction gears, for example, when different cases are used for different reductions, the volume can be optimally downsized and the reduction gear can be made compact, but productivity and cost reduction are desired. In the general-purpose series, it is practically impossible.

Regarding the speed ratio , 1:10
In many cases, about 1: 100 is usually standardized for each kw and made into a series, and particularly for a reduction gear using a parallel gear mechanism, the range from 1:10 to 1:30 to 1:40 is 2 A gear train with three stages is adopted in a range of up to, for example, about 1: 200 in which the speed ratio is large due to the gear train of stages.

るもの、等がある。By the way, in the prior art, in the case of series reduction gears, a case accommodating three stages of gear trains has been standardized and made common, and in the case of two stages of gear trains, one gear train is omitted. One that uses two types of cases with different dimensions for the two-stage gear train and the three-stage gear train, a standard two-stage gear train reducer is set, and the input side or output when there are three stages There is one in which another speed reducer is integrated by retrofitting on the side.

くなる。However, in the case of using the three-stage deceleration case in common, in the case of the two-stage gear train, a wasteful space is generated in the case especially in the front-rear direction, the dimension is unnecessarily increased, and the oil level of the lubricating oil is increased. Changes will easily cause poor lubrication.

It should be noted that a device in which a single-stage speed reducer is added to the input and output sides based on a two-stage gear train speed reducer also increases the size of the device, and easily increases the cost.

する減速機用のケース。1. A case for a speed reducer capable of accommodating a parallel gear train using an output shaft, an input shaft, and an intermediate shaft,
An output-side case having a bottomed tubular shape in which a tubular portion extending rearward from the front wall is integrally provided on a front wall, and a rear edge of the tubular portion of the output-side case is replaceably fitted to a rear wall. A first input-side case having a mounting portion and a second input-side case having a front-rear length of the mounting portion larger than that of the first input-side case.
An input side case group including an input side case of the output side case, the output side case includes an output shaft outlet side bearing seat for supporting the output shaft on the output side on the front wall, and an intermediate shaft on the output side. At least two intermediate shaft outlet side bearing seats for supporting are provided, and the first input side case has an input shaft bearing seat for supporting one end of the input shaft on the rear wall, and the intermediate shaft. Has at least one intermediate shaft receiving side bearing seat for supporting the input side, and the second input side case has an input shaft bearing seat for supporting the input shaft, and the first case. The number of intermediate shaft inlet side bearing seats is larger than the number of intermediate shaft inlet side bearing seats, and one of the cases of the input side case group is selectively attached to the output side case. Case for reducer.
