Gear Motor

Gear Motor is one of the models of RV reducer series worm worm reducer. It is composed of worm and worm wheel, with compact structure, large transmission ratio, and transmission machinery with self-locking function under certain conditions. It is one of the most commonly used reducer.

RV 63 reducer in accordance with the national standard GBl0085-88 cylindrical worm wheel worm parameters, absorbing the most advanced technology at home and abroad, a unique and novel "square box" shape structure, the box shape is beautiful, with high-quality aluminum alloy die cast, has the following advantages:

1, compact mechanical structure, light volume and shape, small and efficient;

2, good heat exchange performance, fast heat dissipation;

3, easy installation, flexible and light, superior performance, easy maintenance and repair;

4, smooth operation, low noise, durable;

5, strong applicability, safety and reliability.

At present, it has been widely used in various industries of production process equipment mechanical deceleration device, which is well received by users. It is the best choice for modern industrial equipment to achieve large torque, large speed ratio, low noise, high stability mechanical deceleration transmission control device.

 Product structure diagram

1, smooth transmission, vibration, impact and noise are small, large deceleration ratio, wide versatility, can be used with a variety of mechanical equipment.

2, can obtain a large transmission ratio with single stage transmission, compact structure, most models of reducer have good self-locking, the mechanical equipment with braking requirements can save the braking device.

3. The engagement friction loss of the worm tooth and the worm tooth surface is large, so the transmission efficiency is lower than the gear, easy to heat and higher temperature.

4. Higher requirements for lubrication and cooling.

5, good mutual matching, worm wheels are manufactured according to the national standards, bearings, oil seals are used with standard parts.

6, the box type has basic type (box body is vertical or horizontal structure with floor plate) and universal type (box body is cuboid, many sides with fixed screw holes, not with floor plate or another foot plate and other structural types)

7, the input shaft connection mode has the basic type (single input shaft and double input shaft), with the motor flange two kinds.

8. Output and input axis position direction and input axis down and up; output axis up and down; input axis up and down.

9, available RV 63 reducer and other RV series reducer 2 or 3 multi-stage reducer, in order to obtain a great transmission ratio.

Product Overview Product summary

Single-stage worm gear reducer

Using the high-quality aluminum alloy die-casting box body,The appearance is light

● High load bearing capacity, stable transmission, low vibration, low noise.

● A variety of connection structures with power input and torque output to meet the needs of various connections; box shape design and base hole layout adapt to a variety of installation methods, strong versatility.

● Small and medium-sized box is fully closed structure, strong sealing, the lubricating oil inside the box is not easy to loss and deterioration, do not need to be replaced, easy maintenance.

 Double-stage worm gear reducer

● It is composed of a single-stage worm reducer, with all the advantages of a single-stage worm reducer, and obtaining a large transmission ratio.

● Common dual-stage combination models are: 25 / 30,25 / 40,30 / 40,30 / 50,30 / 63,40 / 75,40 / 90,50 / 110,63 / 130,63 / 150. If users have special requirements, they can choose 25,30,40,50,63,75,90,110,130,150 as combined units according to actual needs.

Selection method Servicefactor

In order to correctly choose the NMRV worm reducer, please first understand the following points:

● load conditions application frequency M book cong 2 don't die from the ground to pay mountain

● work operation situation Determine the working condition coefficient K1 and the working condition correction coefficient K2

● Mechanical load types A, B, and C are determined according to Table 1.

● According to Table 2, check the working condition correction coefficient K2.

Selection of mechanical load types (Table 1)

Table 1 machinery load classification selection

Work condition correction factor K2 is selected (Table 2)

The working condition coefficient K1 is selected (Figure 1) Diagram 1 working condition coefficient K1

 Select the reducer

● The user must first determine the input mechanical load T (torque) of the working machine, T multiplied by the working condition coefficient K1, and then multiplied by the working condition correction coefficient K 2, that is, to obtain the output torque value of the reducer, and combined with the speed ratio or output speed value, select the required reducer specifications.

● The user can also calculate the output torque according to the known input power, combined with the ratio value or the output speed value, and select the reducer.

Sample selection

Example 1. Universal conveyor belt (uniform load)

Torque: 19N.m running time 8 hours / day

Speed: about 55 r/min, start frequency: 10 times / hour

Reducer: 1 / 25, ambient temperature: indoor 25℃

① According to Table 1, the load type is determined

Load type: no impact uniform load, select A;

② According to FIG. 1, take the frequency intersection point of 10 times / hour on line A, and find out the coefficient K1=1 of the running time of 8 hours / day;

③ According to Table 2, the coefficient K2=1;

④ Then the torque value is 19 K1 K2=1911=19 N. And m, with the optional nearest 19 N. The speed reducer of m.

Selected result: NMRV30-1 / 25

Input power is 0.18kW, output speed is 56 rpm, and output torque is 21 N.m

Example 2. Conveyor belt (medium impact load)

Torque: 65N. M., running time: 16 hours / day,

N,00 times / hour,

Reducer: 1 / 60,"Bad temperature: 35℃, motor direct connection

① According to Table 1, the load type is determined

Load type: mild impact load, select B;

② According to FIG. 1, take the fulcrum of frequency 100 times / hour on the B line, and find the coefficient of 16 hours / day of running time K1=1.65;

③ According to Table 2, the coefficient K2=1.15;

④ The torque value is 65xK1xK2=70x1.65x1.15=1 23 N. And m, can choose the nearest 123N. The speed reducer of m.

Selected result: NMRV63-1 / 60
