How to install a shaft-mounted geared motor.Here we mainly explain the installation relationship between the shaft-mounted geared motor and the working machine, the connection between the shaft-mounted geared motor and the working machine, and the installation of the counter-torque bracket.Let's describe in detail how to install it.
1. The installation relationship between the shaft-mounted geared motor and the working machine
In order to avoid the deflection of the main shaft of the working machine and the additional force on the bearing of the reducer, the distance between the reducer and the working machine should be as small as possible without affecting the normal work, and its value is 5-10mm.
2. The connection between the shaft-mounted geared motor and the working machine
The reducer is directly set on the main shaft of the working machine. When the reducer is running, the reaction torque acting on the reducer casing is balanced by the reaction torque bracket installed on the reducer casing or by other methods.The machine is directly matched, and the other end is connected with the fixed bracket.
3. Installation of counter moment support
The anti-moment bracket should be installed on the side of the working machine facing the reducer to reduce the bending moment added to the working machine shaft.Rubber and other elastic materials are used for the shaft sleeve at the joint end of the reaction moment support and the fixed support to prevent deflection and absorb the generated torque fluctuation.
What needs to be paid attention to during installation is our common concern. The following is the correct method and technical knowledge of installing the reducer.
1. When the reducer is calibrated, steel pads or cast iron pads can be used. The height of the pads does not exceed three, and it can also be done with iron. However, after the reducer is calibrated, it should be replaced with a flat pad. The reducer {[ Note on t1]}.
2. When installing the reducer on the foundation, the R series helical gear hard tooth surface reducer must first calibrate the installation centerline elevation of the reducer, and configure the levelness and the relevant dimensions of the connected parts.
3. The installation method of the cycloidal reducer must be equipped with pulleys, couplings, sprockets and other couplings on the output shaft, and direct hammering is not allowed when installing these couplings. The installation method of the reducer, Worm gear reducer, because the output shaft structure of the cycloid reducer cannot bear the axial impact force, so the screw hole at the shaft end can be screwed into the screw to press into the coupling during installation.
4. The lifting ring screws on the reducer are only used for lifting the reducer.
5. The irrigation in the cement slurry of the reducer should be dense, and the standard is that there are no air bubbles, voids and other defects during installation.
6. The configuration of the pads of the reducer should avoid deformation of the machine body. It should be arranged symmetrically on both sides of the foundation bolts, and the distance between them should be sufficient to allow the water slurry to flow freely during irrigation. Points for attention of the reducer Selection.The concentricity of the calibration shaft should not exceed the allowable range of the coupling.
7. Choose GB1568-79 to match the shaft diameter of the output shaft and input shaft of the reducer.
Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
How to provide goods?
Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
What is the payment term?
When we provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
How to ensure the quality of your products?
First, we will check after each process. For finished products, according to customer requirements and international standards.
How many employees does your company have? What is the relationship between technicians?
We now have more than 180 employees, including 36 engineers and 28 QCs.
What is the ability of your company?
We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
