この発明は船外機や船内外機などの船舶用エン

エンジン冷却水を機外からエンジンへ供給する。 Inboard and outboard motors use a water pump that rotates a rubber impeller inside a pump case that is entirely or partially eccentric to the rubber impeller. Supply cooling water to the engine from outside the aircraft.

で、インペラの各ベーンのたわみ量は不均等にな
るからである。 In such a water pump, when the impeller rotates within the pump case, a reaction force due to deflection of the vanes of the impeller acts on the pump drive shaft. In other words, the impeller is rotated eccentrically within the pump case, or the impeller is rotated within the pump case where part of the inner surface is eccentric, so the amount of deflection of each vane of the impeller becomes uneven. It is from.

る。 On the other hand, in conventional pumps, the bush of the impeller and the pump drive shaft passing through the bush are connected by a half-moon key (Udraf key) in consideration of impeller replacement. Since the reaction force due to the deflection of the vane always acts in one direction between the bush and the pump drive shaft, a small gap is formed between the bush and the pump drive shaft at the position where the amount of vane deflection is small. be done. This gap moves relative to the impeller and the pump drive shaft as the impeller rotates. If mud or sand enters the gap between the bush and the pump drive shaft, the relative movement between the bush and the pump drive shaft will accelerate the wear of both, especially around the keyway of the half-moon key. Increased wear.

不都合がある。 In addition, in order to prevent water, mud, and sand from entering the gap between the bush and the pump drive shaft, a lip is formed on the impeller that tightly adheres to the circumferential surface of the pump drive shaft. There is a type in which both ends are closed, but in this case, the above-mentioned relative movement accelerates wear of the lip, making the tightness of the lip to the pump drive shaft unstable.

も確実になる。 5 and 6 are cross-sectional views showing the action of this tangent key 70. FIG. 5 shows the transmission shaft 14 in a stationary state, and FIG. 6 shows the transmission shaft 14 rotating in the direction of arrow A. In the stationary state of the transmission shaft 14, the tangential key 70 is connected to the key fitting portion 72.
and the recess 74 with a small gap required for assembly. When a driving force larger than a driving reaction force that is approximately equal to the sum of the frictional force within the pump case of the impeller 48 and the discharge pressure of the cooling water is applied from the transmission shaft 14 in the direction of arrow A, the impeller 48 Rotate in direction A.
That is, when the impeller 48 rotates, a force greater than the drive reaction force in the opposite direction of arrow A is always applied to the tangential key 70. Therefore, the tangential key 70 rotates slightly in the direction of arrow A and moves in the opposite direction of arrow A, so as to push open the gap between the bush 52 and the transmission shaft 14 while closely contacting the inner surfaces of the key fitting part 72 and the recess 74. It acts on i.e. tangent key 7
0 wedges between the key fitting portion 72 and the recess 74 to firmly connect the bush 52 and the transmission shaft 14. In this way, the tangential key 70 acts as a wedge to separate the concave portion 74 of the bushing 52 from the power transmission shaft 14 while the water pump 30 is in operation, so that this separation force (separation force F 1 ) is sufficiently larger than the reaction force due to the deflection of the vanes 50 of the impeller 48 (deflection reaction force F 2 ). Therefore, even in the position shown in FIG. 6 where the deflection reaction force F 2 acting on the tangent key 70 is at its maximum, the separation force F 1 due to the wedge action is the deflection reaction force F 2 .
Since it is sufficiently larger, no gap is formed between the bushing 52 and the transmission shaft 14. That is, no relative movement occurs between the impeller 48 and the transmission shaft 14 due to the deflection reaction force F2 of the vane 50, and the two always rotate as one. As a result, there is no flow of water between the bush 52 and the transmission shaft 14 due to the rotation of the impeller 48, and wear caused by mud and sand flowing with the water is significantly reduced. As shown in FIG. 6, while the water pump 30 is in operation, a slight gap 78 is formed between the key fitting part 72 and the recessed part 74, but since there is no relative movement, there is no gap 78 caused by mud or sand. No wear occurs. Furthermore, in this embodiment, since the impeller 48 is formed with a lip 76, the lip 76 restricts the flow of water into and out of the gap 78, further reducing wear. On the other hand, since there is no relative movement, the lip 76 itself There is no wear and tear, and the sealing action of the lip 76 is ensured.

水パイプ３６を通りエンジンへ圧送される。 When the impeller 48 rotates in the direction of arrow A in FIG. 3, the volume formed between the vane 50 and the pump case increases near the inlet 54, so water from outside the boat flows into the pump chamber 46, and the discharge Since the volume between the vane 50 and the pump case gradually decreases near the outlet 56, the water in the pump chamber 46 is forced to flow from the outlet 56 through the water pipe 36 to the engine.

る。 As described above, in this invention, a key fitting part is formed which is cut in a plane tangent to the pump drive shaft and parallel to the axis, while the impeller bush has a center of curvature that is offset from the center of curvature of the pump drive shaft. An arc-shaped recess is formed, and a key having an approximately half-moon cross section and long in the axial direction is inserted between the key fitting part and the recess, so that the key is attached to the pump drive shaft during pump operation. The relative movement between the pump drive shaft and the key as the pump rotates creates a wedge effect. Due to this wedge effect, the key is strongly wedged between the bush and the pump drive shaft, and the two rotate together without relative movement. This prevents mud and sand from flowing in between the bush and the pump drive shaft, along with water, which significantly reduces wear on the bush, pump drive shaft, and key, and improves durability.
