本発明は、舶用減速逆転機であって、特に、前進２速式
の本のに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a marine speed reduction/reversing machine, and more particularly to a two-speed forward gear.
このように、前進２速を備えた減速逆転機は、主として
、漁船用等に使用されるものであるが、この場合、前進

が固定されてしまう欠点があったのである。As described above, reduction/reversing gears with two forward speeds are mainly used for fishing boats, etc., but in this case, even though they have two forward speeds, the required reduction ratio is not uniform. , which differs depending on the working conditions of each region, etc., and in order to meet such demands, it is desirable to be able to freely change the reduction ratio of the second speed. In addition, the demand for marine reduction/reversing gears is two-speed type with two forward speeds,
There are cases in which only one speed is available, and therefore, there are cases in which only one forward speed is available and those with two forward speeds in the same case, and each part such as gears is used for the same purpose. This is advantageous in terms of cost. In other words, it would be desirable for such a reduction/reversing machine to be able to function as a one-speed forward type and a two-speed forward type, and to be able to freely change the reduction ratio of the two forward speeds. , a reduction/reversing gear that combines all of these has not been realized, and even though the reduction ratio of the two forward speeds can be freely selected, it has a completely side structure compared to the one forward speed type, or vice versa. However, models that could be used interchangeably as a single forward speed type or a two forward speed type had the disadvantage that the reduction ratio of the second speed was fixed.

小歯車（９） ＜９）へ噛合している。For example, FIG. 1 is an example of the latter, and this will be explained based on the diagram. In the figure, (1) is a reverse input gear that is connected to the engine and also serves as an input gear, and (2) is A reverse small gear is disposed alongside the reverse input gear (1) and is connected to the reverse input gear (1) via a reverse clutch (3), and this reverse small gear (2) is propeller(
The reverse input gear (1), the reverse clutch (3), and the reverse small gear (2) constitute a reverse unit (6). (7) (7) is a pair of forward first speed input gears arranged symmetrically on the lower side of the reverse input gear (1) and meshing with the reverse input gear (1);
At the rear of the first forward speed input gear (7) (7), a gear is connected concentrically with the first forward speed input gear (7) (7) and via the first forward speed clutch (8) (8). , forward 1st speed small gear (9) connected to this forward 1st speed input gear (7) <7)
) (9) is arranged, and this forward first speed pinion <9) (
9) mesh with both upper sides of the large output gear (5), and these constitute a pair of forward one-speed units (10) (10). On the other hand, (11) and (11) are a pair of forward two-speed input gears that are arranged symmetrically on the upper side of the reverse input gear (1) and mesh with the reverse input gear (1). , this forward two-speed input gear (11) (11
) are located concentrically with the two forward speed input gears (11) (11).
A forward two-speed small gear (13) (13) connected to the forward two-speed clutch (12) (12) is arranged to
These allow a pair of forward two-speed units (14x14
), as well as two forward speed small gears (13) (13
) are meshed with the first forward speed small gear (9) <9) through intermediate gears (15×15), respectively.

By adding the following, it is therefore possible to make the structures of the forward one-speed type and the two-speed type compatible with each other. In this case, the reduction ratio of the second forward speed is the second forward speed input gear (11
) (11) and the reverse input gear (1). Therefore, by changing this tooth ratio, the reduction ratio can be changed freely. However, this It is also related to the reduction ratio of Therefore, since the distance between each axis is always fixed, the forward movement 2
Since the diameter of the speed input gear (11) is already determined by this, it is not possible to freely select any other reduction ratio.

は、各速とも同様である。The present invention eliminates these conventional drawbacks and has a structure that allows both forward 1-speed entry and 2-speed type to be used together, and also allows the reduction ratio of the 2 forward speeds to be freely selected. The structure will be explained based on the illustrated embodiment. In the embodiment of the present invention shown in FIG. 2, in contrast to the conventional structure shown in FIG. The 2nd speed input gear (11XII) is not meshed with the same reverse input gear (1) as in the past, but instead of being meshed with the same reverse input gear (1) as in the past, the second speed input gear (11XII) is meshed with the reverse input gear (1). One forward 2nd speed drive input gear (16) is attached to rotate integrally with the reverse input gear (1), and the 1st forward speed input gear <7) <7) is the conventional reverse input gear (1).
However, the second forward speed input gear (11) is designed to mesh with this second forward speed drive input gear (16). In other words, forward l speed input gear <7) <7)
is for the reverse input gear (1) and the forward 2nd speed input gear (1).
1) In (11), the power is transmitted by the drive input gear for forward 2nd speed (16), but the reduction ratio of the 2nd forward speed is determined by the drive input gear for 2nd forward speed that is unrelated to the 1st forward speed. (1
6), and therefore, the reduction ratio of the first forward speed and the reduction ratio of the second forward speed can be freely selected without being constrained by each other. In the reduction/reversing gear, it is possible to obtain any reduction ratio according to the demand. 0 FIG. 3 shows an actual assembly diagram of the present invention, and the reverse input gear (1) is To the front end of the reverse input shaft (17), the rear input shaft 7
The boss (1a) of the reverse input gear (1) is fitted to rotate integrally with the shaft (17), and the boss (1a) of the reverse input gear (1) projects forward of the case (18), to which a shaft coupling (19) connected to the engine is attached. However, in this example, case (18)
Between the front wall and the reverse input gear (1), the second forward speed drive input gear (16) is connected to the reverse input gear boss (1a).
) by hydraulic fitting or the like so that they rotate together. The reverse flange (3) is connected to this reverse input gear (1).
A hydraulic piston (22) and a friction plate (23) are installed between the /'1 housing (20) that extends further rearward and the cylinder shaft (21) that extends further forward than the reverse small gear (2). The structure of the latch is the same for each speed.

6), but as shown in Figure 2, the forward 1st speed input gear <7)
<7). These Go input 41] (24) and the input gear (26) are used when inputting power from the engine coaxially with the output shaft (25).

The signal is transmitted from the forward 1st speed input gear (7) (7) and the reverse input gear (1), and furthermore, the forward 2nd speed is transmitted to the reverse input gear (1) and the forward 2nd speed drive input gear ( 16
). Although not shown in FIG. 3, four shafts for the forward first speed and forward second speed units are arranged above, below, left and right of the reverse input shaft (17).

いう、従来では得られなかった顕著な効果を。As described above, according to the present invention, the reduction ratios of the first forward speed input gear and the second forward speed input gear are determined by the ratio of the number of teeth to each other input gear, and therefore, the ratio of these teeth is , can be arbitrarily set independently of each other, and therefore, without being constrained by the single forward speed reduction ratio, various two forward speed reduction/reversal machines with different reduction ratios can be used according to the customer's request. can be provided. Moreover, in the present invention, changing the gear ratio in this case does not require changing the distance between the shafts, etc., and therefore, such a change in the reduction ratio can be performed using the same case. is possible, and if only 1 forward speed is required, remove the 2nd forward speed manual gear, etc., and on the other hand, if 2 forward speeds are required, replace the 2nd forward speed input gear with the 1st forward speed 2. etc., the parts can be shared between the
Although it has a common structure with the same speed type, it also allows you to select the reduction ratio of the 1 forward speed type and the 2 forward speed type, which is a remarkable effect not previously available.
