Description

Oil circuit system of conical twin-screw reducer

technical field

The utility model relates to an oil circuit system of a conical twin-screw reducer. It belongs to the technical field of mechanical equipment.

Background technique

The conical twin-screw reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque.

The oil circuit system of the existing conical twin-screw reducer can only be lubricated in one direction, that is, oil enters the shaft when it is rotating forward, and does not enter oil when the shaft is rotating reversely. Therefore, if the reverse time is longer, the oil temperature will be too high. High, which will damage the parts of the reducer, and will burn out in severe cases.

Contents of the invention

The purpose of this utility model is to overcome the above disadvantages and provide an oil circuit system of a conical twin-screw reducer. This reducer adopts a bidirectional lubricating pump, which can enter oil when the shaft rotates forward and reverse, and the cooling effect of the oil is good. .

The purpose of this utility model is achieved in that:

An oil circuit system of a conical twin-screw reducer, which is characterized in that: the oil circuit system of the conical twin-screw reducer includes an oil suction filter, a two-way lubricating pump and a plate cooler arranged on the back of the box. The inlet of the oil suction filter is connected to the oil outlet of the tank, the outlet of the oil suction filter is connected to the inlet of the two-way lubricating pump, the outlet of the two-way lubricating pump is connected to the inlet of the plate cooler, and the outlet of the plate cooler is connected to the inlet of the tank. The oil port is connected.

Compared with the prior art, the beneficial effects of the utility model are:

1) The utility model is an oil circuit system of a conical twin-screw reducer. The two-way lubricating pump is attached to the box and integrated with it and does not need to provide power. When the shaft rotates forward or reverse, the two-way lubrication The oil inlet and outlet of the pump remain unchanged, so it can effectively prevent the oil temperature in the box from being too high.

2) The utility model is an oil circuit system of a conical twin-screw reducer. The oil outlet of the box is connected to the oil suction filter, which can filter impurities in the oil and prevent subsequent components from being blocked.

3) The utility model is an oil circuit system of a conical twin-screw reducer. The high-temperature oil coming out of the box is cooled in the plate cooler, and the oil can quickly cool down, and then enters the box for circulating lubrication.

Detailed ways

Referring to Fig. 1-3, the utility model relates to an oil circuit system of a conical twin-screw reducer, which is installed on a box body 1, the lower part of the box body 1 is the input shaft 6, and the upper part of the box body 1 is the output shaft 7 The side of the box 1 is provided with a sight glass 2, which is used to observe the oil level of the box 1. The oil circuit system of the conical twin-screw reducer includes an oil suction filter 3, a two-way lubrication pump 4 and a plate cooler 5 , the oil suction filter 3, the two-way lubricating pump 4 and the plate cooler 5 are arranged on the back side of the box body 1, the inlet of the oil suction filter 3 is connected with the oil outlet of the box body 1, and the outlet of the oil suction filter 3 is connected with the oil outlet of the box body 1. The inlet of the two-way lubricating pump 4 is connected, the outlet of the two-way lubricating pump 4 is connected with the inlet of the plate cooler 5, and the outlet of the plate cooler 5 is connected with the oil inlet of the box body 1.

working principle:

See Figure 3, the dotted line in the figure shows the schematic diagram of the circulation track of the oil in the tank 1, the cooled oil enters the tank 1, the oil level can be seen from the sight glass 2, and the oil lubricates various parts at the output end, The oil will heat up at this point.

Referring to Fig. 1, under the action of the bidirectional lubricating pump 4, the lubricated oil in the tank 1 is drawn out through the oil suction filter 3, then enters the plate cooler 5 for cooling, and finally enters the tank 1 again for circulation.

The two-way lubricating pump 4 is small in size, can be attached to the casing 1 and be integrated with it and does not need to provide power specially. When the shaft rotates forward or reversely, the oil inlet and the oil outlet of the two-way lubricating pump 4 remain unchanged. When it is stopped for a long time and then restarted, it can also automatically start with oil suction, because it has the functions of automatic lubrication and automatic wear compensation, and it does not require daily maintenance and has a long service life.
