What are the characteristics of the names of walking assembly and slewing assembly and what are the

Can you tell us more about that? Convenient for us to give advice.

The travel assembly includes a travel pump (travel motor) and a travel reducer (travel gearbox).

The rotary assembly includes a rotary pump (rotary motor) and a rotary deceleration and (rotary pressure box).

In fact, there is not much difference in appearance and type.

The main difference is the difference in performance, the travel motor and the swing motor basically require low speed and high torque, the required speed is not very high, but the output torque is relatively large to overcome the load.

Ordinary motors are not necessarily in this regard, and the matching relationship between speed and torque will be comprehensively considered to ensure that the motor can meet the working requirements.

Strictly speaking, the walking motor should be called the walking reducer, and the rotary motor is called the rotary reducer, and the ordinary motor is the motor, and the motor can also be used for walking and flexible use!

Both walking and slewing are driven by hydraulic pressure and belong to hydraulic motors. Ordinary motors are electric motors. This is the most basic difference.

Hello copy, these deceleration mechanisms are the principle of planetary deceleration.

1. To put it simply, there are three types of components: the sun gear, the planetary gear, and the DAO planetary carrier and gear ring.

2. How to install it:

a. The upper part of the deceleration mechanism is connected to the motor, and the output shaft of the motor is the input shaft (sun gear) of the deceleration mechanism.

B. The lower part of the deceleration mechanism is connected with the main frame and the rotary large gear ring respectively, the static part of which is connected to the reducer gear ring and the main frame, and the moving part is connected to the output shaft of the reducer and the rotary large gear ring.

3. Working principle:

a. Sun gear drive planetary wheels and planet carriers.

b. The planetary gear makes planetary motion around the sun gear on the gear ring of the reducer, and at the same time reduces the speed and outputs an output shaft.

c. The output shaft of the reducer is engaged with the rotary large gear ring to promote the excavator to rotate.

Travel motor.

The reducer, motor body and valve control part of the rotary motor are made into an integrated assembly, and installed on the excavator as a version assembly.

When installing, first align the marks of the swing motor assembly flange and the travel motor assembly flange on the frame and the driving wheel, and tighten the flange bolts according to the specified torque after putting on the flange bolts. Finally, the hydraulic lines corresponding to the motor assembly are installed, with 5 pipes on the rotary motor and 4 pipes on the travel motor. Ensure the integrity of the sealing ring at the joint when the pipe is connected.

After the installation is completed, a light load test run is used to check whether there is abnormal vibration and pipeline leakage, and finally the load is gradually loaded until the overflow to ensure that the assembly is well installed.

That's a bit of a difficult question for you, but you're wondering how to switch between the second speed?

Walking time within. The throttle is maximum, and the walking mode selects the "two-speed" gear, which is the "rabbit" gear downstairs, and the general two-speed gear has a rabbit symbol, press it, and then push the walking pedal valve to the maximum position, and the walking motor will achieve high-speed walking; When encountering an uphill slope, the engine speed decreases, and the main system pressure is lower than 270MPa (different manufacturers and different models), the second speed will automatically become one speed (low speed).

What is called automatic deceleration, the drive assembly of the excavator is composed of a hydraulic motor and a reducer, and the hydraulic motor is generally selected

The quantitative plunger motor "capacity", that is to say, he will turn as fast as the main pump gives him as much oil, and he will not change the speed by himself. The reducer is a mechanical deceleration, and the deceleration rate is fixed. Therefore, the speed of the entire drive assembly is affected by the main pump, and the drive assembly will not change the speed.

When we select the rabbit gear or the turtle gear on the control panel, the speed of the drive is changed, because when we select the gear, we actually adjust a solenoid valve on the main pump, which will change the amount of oil supplied to the motor by the main pump per unit time, so the walking speed is changed.

The deceleration is done by the reducer, but I think you should ask how to change the gear, and the reducer has a hydraulically driven shift mechanism inside.

The landlord didn't make it clear. Do you score tracked or wheeled. Generally, there are many wheel types, and it is estimated that you are talking about the crawler type, which is mainly composed of four wheels (drive wheels, idlers, rollers, drag sprockets and tracks).

The reducer of the travel motor and the Duan Fuliang rotary motor, the motor body and the valve control part are made into an integrated assembly, and installed on the excavator as an assembly.

When holding the wide installation, first align the marks of the rotary motor assembly flange and the walking motor assembly flange on the hall pin frame and the driving wheel, and tighten the flange bolts according to the specified torque after putting on the flange bolts.

What skin shouts to set up a scattered preparation. If the hydraulic motor burns the walking assembly of the field, check the high-pressure relief valve and shuttle valve. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】
