造製ミッションケースに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an input side speed change shaft, an output side speed change shaft that is directly interlocked with the input side speed change shaft and can freely change forward speed, and the input side speed change shaft. The present invention relates to a cast transmission case in which a rotation shaft of a reverse gear is directly interlocked with the output speed change shaft to freely change reverse gear transmission.

しかし、中子を使用して鋳造するためには、木型及び砂

ために＃ｉ品ココスト高くなるという問題があった。However, casting using a core not only complicates the structure and manufacture of the wooden mold and sand mold, but also increases the cost of the #i product due to extensive construction work.
本発明の目的は、中子を使用せずにミッションケースを
鋳造できるようにする点にある。An object of the present invention is to enable casting of a transmission case without using a core.

シである。The characteristic structure of the uninvented cast transmission case is that the mission case is divided into parts along a virtual plane passing through the centers of the bearings of both transmission shafts, and an opening for inserting and removing the reverse gear is formed in the transmission goose. A lid is attached to the opening via bolts, and a bracket for supporting the rotating shaft is attached to the lid.The operation and effect thereof are as follows.

ションケースは中子を使用せずとも鋳造できる。In other words, the holes for the bearings for both transmission shafts are formed on the split surface of the transmission case, and it is possible to form an opening through which the reverse gear can be inserted and removed without forming a hole for the bearings for the rotating shaft in the transmission case. Since the rotating shaft is supported by a bracket attached to the lid of the opening, the transmission case can be cast without using a core.
従って、製作が簡単にできるようになるばかシか、工数

うになった。Therefore, it has become easier to manufacture, the number of man-hours has been reduced, and the entire transmission case has become cheaper.
次に、本発明の実施例を、図面に基づいて説明する。 Next, embodiments of the present invention will be described based on the drawings.

構成シである。As shown in Figs. 1 and s2, the input side transmission shaft (2) is fitted onto the shift gear 1llt and rotates integrally, and the forward gear (3) is selectively engaged with the shift gear t1). The shaft (4) and the rotating shaft (6) of the reverse gear (6) which is selectively engaged with the shift gear +11 and which transmits reverse gear freely to the output side speed change shaft (4) are mounted in a cast transmission case (9). The transmission is configured internally.
