Abstract

PURPOSE:To prevent any drag of oil and seize of a clutch from occurring by using a spring consisting of a temperature sensitive member whose energizing pressure is varied by a lubricating oil pressure regulating valve according to oil temperature, and decreasing an oil level when the oil temperature is low but increasing it when temperature is high. CONSTITUTION:Lubricating oil pressure in an oil path 20 is regulated to be low at time of low temperature but high at time of high temperature by a lubricating oil pressure regulating valve 30 whose spring is made up of a temperature sensitive member, whereby oil pressure in oil paths 21, 22a and 22b is equally supplied. When a forward-backward selector valve 3 is in a forward position 3b and a shift selector valve 4 is in a forward first gear speed position 4a respectively, hydraulic fluid passed through a trolling valve 9 is fed to a forward first gear speed clutch 2a from oil paths 13, 12a, and lubricating oil is supplied from oil paths 24, 33, 32a and 22a. The amount of lubricating oil in the clutch 2a becomes more than that of other clutches, so that seize of the clutch 2a at time of high temperature and low speed is thus kept back. This state is the same even in regard with other clutches, thus more lubricating oil than others is supplied to the clutch being used, through which any seize at time of high temperature and low speed is preventable in this way. In addition, any drag of oil at time of neutral and low temperature is also preventable.

(Prior art and its problems) A lubricating oil pressure regulating valve is generally installed alongside a lubricating oil passage, and drains a portion of the lubricating oil flowing through the lubricating oil passage, and adjusts the drain amount to reduce the amount of lubricant flowing through the lubricating oil passage. The amount of oil is adjusted, and the amount of drain is adjusted by changing the restriction of the drain passage using a piston biased by a spring. In conventional lubricating oil pressure regulating valves, the strength of the spring is constant regardless of temperature changes, so the drain amount is constant regardless of the lubricating oil temperature, and the amount of oil flowing through the lubricating oil path is constant. Therefore, due to changes in the viscosity of the lubricating oil due to temperature changes, the oil pressure increases when the temperature is low and decreases when the temperature is high. On the other hand, a marine multi-stage reduction/reversal machine having one reverse clutch and a plurality of forward clutches is equipped with a forward/reverse switching valve that switches between forward and backward movement, and an 8-speed switching valve that switches forward movement into multiple stages. When the forward/reverse switching valve is in the neutral state and the temperature is low, the oil pressure is high as described above, causing a problem of rotation. FIG. 3 is a diagram showing the relationship between lubricating oil pressure, clutch rotation speed, and drag torque at low temperatures. From FIG. 3, it can be seen that as the oil pressure increases, the rotating torque increases. If the amount of lubricating oil is reduced to prevent this tangle, the oil pressure at high temperatures will be low, which may cause seizure of the clutch friction plate, sliding bearing, etc., especially at low speeds, and if the amount of lubricating oil is increased to prevent seizure. , tangles will occur.

In addition, it is generally difficult to balance the drag torque of the forward clutch and reverse clutch, especially in the second forward gear.
In the case of a deceleration/reversing gear with one reverse gear, when in neutral, the drag torque of the forward clutch and the reverse clutch cannot be balanced, and due to the viscosity of the oil, the drag torque in the forward direction from the forward clutch dominates, causing the propeller to There was a problem in that slow rotation in the forward direction was unavoidable.

(Structure of the Invention) The present invention supplies lubricating oil to each clutch of a marine multi-stage reduction/reversing machine having one reverse clutch and a plurality of forward clutches through a lubricating oil pressure regulating valve that adjusts the oil pressure of the lubricating oil. In the lubricating oil supply system, the lubricating oil passed through the lubricating oil pressure regulating valve is supplied equally to each of the forward and backward clutches, and the lubricating oil is also supplied to the reverse clutch when in neutral and reverse, and when the forward clutch is in use when moving forward. By supplying lubricating oil to the clutch, the lubricating oil pressure regulating valve uses a spring made of a temperature-sensitive member whose biasing pressure changes depending on the lubricating oil temperature, and when the lubricating oil temperature is low, the amount of oil passing through is reduced and the temperature increases. This is a lubricating oil supply system for a marine multi-stage reduction/reversing gear, characterized in that the lubricating oil supply system is configured such that the lubricating oil supply system increases from time to time.

(Operation) When in neutral, more lubricating oil is supplied to the reverse clutch, so the drag torque of the forward clutch and reverse clutch is balanced. Moreover, the lubricating oil pressure regulating valve lowers the oil pressure at low temperatures. Therefore, tangles at neutral and low temperatures are prevented. Additionally, the oil pressure regulating valve increases the oil pressure at high temperatures, and moreover, each clutch used is supplied with more lubricant than the other clutches. Therefore, seizure of each clutch is reliably prevented, especially at high temperatures and low speeds.

That is, the amount of lubricating oil in the forward clutch 2 and the reverse clutch 1 becomes equal, and the drag torque is balanced. Furthermore, the oil pressure of the lubricating oil is regulated by the pressure regulating valve 3o in the same manner as described above. Therefore, tangles at neutral and low speeds are reliably prevented.

(Effects of the Invention) As described above, according to the present invention, the reverse clutch 1
Since a large amount of lubricating oil can be supplied to the forward clutch 2 and the reverse clutch 1, the drag torque of the forward clutch 2 and the reverse clutch 1 can be balanced. Furthermore, by using a spring 30d made of a temperature-sensitive member in the lubricating oil pressure regulating valve 30, the oil pressure at low temperatures is lowered. Therefore, it is possible to prevent twisting at neutral and low temperatures. In addition, the oil pressure at high temperatures is increased by the lubricating oil pressure regulating valve 30, and more lubricating oil is supplied to each clutch being used (for example, 2a) than to other clutches (for example, 1.2b). In particular, it is possible to reliably prevent the clutches 1.2a, 2b from seizing at high temperatures and low speeds.

In a lubricating oil supply system that supplies lubricating oil to each clutch of a marine multi-stage reduction/reversing gear that has one reverse clutch and a plurality of forward clutches through a lubricating oil pressure regulating valve that adjusts the oil pressure of the lubricating oil, The lubricating oil that has passed through the pressure valve is supplied equally to each of the forward and backward clutches, and the lubricating oil is also supplied to the reverse clutch when the vehicle is in neutral or reverse, and the lubricant is supplied to the forward clutch that is being used when the vehicle is moving forward. , the lubricating oil pressure regulating valve is configured to use a spring made of a temperature-sensitive member whose biasing pressure changes depending on the lubricating oil temperature, so that when the lubricating oil temperature is low, the amount of oil to be passed is decreased and when it is high, it is increased. A lubricating oil supply system for marine multi-stage reduction/reversing gears.
