1. Advanced product technology, compact design, beautiful appearance, simple structure, easy operation, maintenance, easy installation, stable starting and other advantages.


2. This product mainly consists of spindle device, reducer, motor, hydraulic pump station, disc brake, depth indicator, coupling and electric control system.


(1) spindle device (spindle device mainly consists of spindle, drum shell, rolling bearing, bearing pedestal, bearing cover, bearing beam, plastic lining, etc. The main shaft is made of high quality carbon alloy steel. The drum is equipped with a fixed car device, which can better maintain the brake and adjust the rope. The roller liner is of high mechanical strength and long service life.


(2) the reducer conforms to the standard JB/T8853-1999, gear accuracy level 6, gears and shaft is made of high quality low carbon alloy steel carburizing and hardening, tooth surface hardness HRC 58-62, has a large carrying capacity, high transmission efficiency, the advantages of compact structure and reliable in use, can be applied to metallurgical mining, lifting transport, cement, construction, chemical industry, textile, light industry, etc.

Main features of the reducer:


1. The gear is made of high strength and low carbon alloy steel by carburizing and quenching, and the hardness of the tooth surface is HRC58 ~ 62.


2. The gear adopts CNC grinding technology, with high precision, stable quality and good interchangeability.


3. High carrying capacity, 7 times more than the carrying capacity of the old soft-tooth surface reducer.


4. The transmission efficiency is high, the single stage can reach 98%, the two levels can reach 97%, and the three-level can reach 96%.


5. Small size, light weight and long service life.


6. Easy to repair and easy to install.


Planetary gear


Compared with ordinary gear transmission, the main features of planetary gear transmission are as follows:


1. Small size, light weight, compact structure, large transmission power and high bearing capacity are determined by internal factors such as the structure of planetary gear transmission.


2. The transmission ratio is large.


As long as the appropriate choose the type of planetary transmission and distribution scheme, can use a few of the gear and get a lot of planetary gear transmission because of its three basic transmission ratio component can drive, so it can realize the synthesis and decomposition of movement, and the step and stepless variable speed drive and other complex movement.


3. High transmission efficiency.


Due to shunt transmission structure of planetary gear transmission using the symmetrical, uniform distribution with a number of planetary gear, used in the center of tooth and the arm bearing reaction force balance each other, conducive to the transmission efficiency, the transmission type under the condition of a proper and reasonable structure layout, the efficiency can reach 0.97 to 0.99.


4. Strong ability of movement balance, shock resistance and vibration.


Due to the use of several identical planetary wheels, it is evenly distributed around the central teeth, which can balance the inertial ability of the planetary tooth and the arm. At the same time, the number of teeth engaged in meshing is increased, so the motion balance of planetary gear transmission is stronger and the work is more reliable.


Disk brake


(1) the disc brake is applied in mine hoist braking system of the hydraulic actuators, accurate name should be: often closed rear disc brake cylinder, is currently USES more rear type oil cylinder, in order to meet the needs of the continuous development of mining industry, disc brake gradually obtained the development application.


Its main advantage is to overcome some disadvantages of the lever brake, the structure is compact, safety is good, the action is sensitive, convenient for the mine to improve automation.


In the elevator starts, the output pressure of the hydraulic pressure station open the brake oil, elevator start to work, when work braking, working condition of hydraulic station, according to raise or lower the pressure, brake will provide brake force, on the other hand, the accident situation, the pressure of the hydraulic pressure station to return to the residual pressure, brake with maximum braking force to hoist parking in the shortest possible time.


(2) depth indicator.


The depth indicator is the arch depth indicator, and the driver can understand the position of the container visually. Its motion is transmitted through two sprockets and sleeve roller chains. Simple structure and reliable indication. In addition, according to the depth of the user's wellbore, change the size of the driven sprocket to change the distance of the needle and give the driver a clear and visible indication.


1. Indicate the position of the lifting vessel in the wellbore;


2. The container is close to the wellhead or the bottom of the well to send a deceleration signal;


3. When the hoisting container is overrolled, the end switch of the depth indicator is switched off, so that the protection circuit is tripped and the emergency brake is carried out.


4. When the depth indicator fails, protect and alarm the device to ensure the safe operation of the equipment.
