The center of the output shaft 19 to which the gear 12 is attached and the center of the gear shaft hole 23 are machined to ensure accuracy.
When the gear box 18 is attached to the gear box 3, the gear shaft 15 into which the gears 10 and 11 are rotatably inserted enters the gear shaft hole 23 of the gear box 18, so that the gears 12 and 11 mesh with precision. It is done. Furthermore, since the gear shaft 14 also fits into the gear shaft hole 8', the gear box 18 can be assembled into the gear box 3 with high precision. By tightening the gear box mounting screws 24, the two can be completely fixed as one body, thereby supporting the gear shaft 14 and the gear shaft 15 at both ends and increasing their strength. A stepped part 25 is provided on the mating surfaces of the gear box 3 and the gear box 18, and the stepped part 25 is made into a rectangular concave part. Furthermore, a fitting portion 28 into which the support portion 27 of the screw body 26 fits is provided at the tip of the portion of the gear box 18 into which the bearing 20 is press-fitted.
A screw 29 is rotatably inserted into the screw body 26, and a rotary cutter 30 for cutting meat and a fixed cutter 30 with a small round hole are attached to the tip 29' of the screw. The main body cover 31 is tightened and fixed to the screw main body 26. One end 29' of the screw is fitted into a groove 19' at the tip of the output shaft 19 for transmission. The screw main body 26 is provided with an input hole 26'', and when meat is input through this hole, the meat is ground by the rotating cutter 30 and the fixed cutter 3'' as the screw 29 rotates and comes out.Electric motor A cylindrical cooling guide 32 is placed over the rear end of the cooling guide 1 .

転部分の熱による寿命低下を防ぐことができる。The cooling fan 37 rotates as the electric motor rotates, and air enters through the intake hole 1c of the electric motor 1, passes through the interior, exits through the exhaust hole 1d, and is discharged by the cooling fan 37. To attach the gear box and motor part to the outer box, use outer box 38 and outer box 39.
This is done using the tightening screw 40. The method of supporting the gear box 18 when it is inserted is to first insert a cylindrical support rubber 41 into the outer shape of the fitting part 28 of the gear box 18, and support it with the tip support part 42 of the outer box, covering the electric motor 1. A cylindrical support rubber 43 is inserted into the cooling guide 32 and supported by the tip support portions 44 of the outer boxes 38 and 39. In addition, the gear boxes 3 and 18 have a concave support rubber 46 placed over the protruding portions 45 extending in a long flat plate shape from both ends of the gear boxes so as to cover the mating surfaces 25 of the gear boxes 3 and 1. A plate-shaped support portion 47 is provided from the outer case 38 and the outer case 39, and this support portion 47 covers the support rubber 46 and supports it on the outer case.
The tip of the support rubber 46 is shaped like a flange 46'', and the flange 46'' is positioned between the tip 47'' of the central support portion 47 and the flat portion 48 provided below the gear box 3. to prevent gear boxes 3 and 18 from moving.
The outer boxes 38 and 39 are connected to the outer boxes 38 and 39 through the collar-shaped portion 46'' of the support rubber 46.
An enclosure 49 is provided on the lower side of the motor 1 of the outer boxes 38 and 39 to protrude into the outer case.
is housed wrapped in a cushioning material 51 made of foamed styrene and polyethylene. Intake holes 52 are provided in the outer boxes 38 and 39 directly below the gear boxes 3 and 18, and the cooling air is guided to the gear box 3 side by the enclosure 49 and enters the intake hole 1c of the motor 1 while cooling it. cooling fan 3
7, the gas is discharged to the outside from the exhaust hole 53 of the outer box.
A hot air exhaust hole 54 is provided in the upper part of the gear box 3, and cooling air is used to remove the heat generated by the bearings and gears inside the gear box.While cooling the gear box, the negative pressure inside the outer box is used to remove hot air. The hot air inside the gear box is also lowered through the exhaust hole 54.
Moreover, the hot air exhaust hole 54 is provided on the side of the intake hole 1c of the electric motor to prevent dirt, dust, etc. from entering when the air is taken in. As described above, according to the gear device of the present invention, even if the rotational friction heat of the gears and bearings in the gear box increases due to load, the intake hole is installed at the bottom of the gear box and the air intake hole is installed inside the outer box. Since the cooling air is guided by the protruding enclosure and hits the gear box, the gear box is cooled and at the same time the ambient temperature inside the gear box is also lowered, reducing the rotational friction heat of the gears and bearings. It is possible to prevent a decrease in lifespan.
そして構成は実施例のようにオモリ等を支持する囲いを
利用して冷却空気を案内しているため、合理的な構成と
なつているものである。The structure is a rational structure because the cooling air is guided using an enclosure that supports weights and the like as in the embodiment.
