Products Description

NMRV gearbox

NMRV reducer is a new type of reducer. also known as RV reducer. “NMRV” is a general term. it refers to the aluminum reducer. the world has been used to aluminum reducer called “NMRV reducer”. The main components are oil seal. oil plug. worm gear box. ball bearing. output shaft. worm wheel. worm. output shaft. motor disk (flange). output shaft cover. hexagon socket head screw. double round key. gasket. etc. BHADE reducer. one of NMRV series. has single flange input. flange output or double shaft output.

  • Characteristics

The weight of NMRV reducer is relatively light. the shell is made of aluminum alloy. which has the advantages of light weight. superior strength. exquisite appearance. high heat dissipation performance. long service life. noiseless movement and other advantages. convenient and simple connection with the motor. NMRV reducer is a kind of practical transmission equipment. and its appearance design and its integration are more in line with public demand than other types of reducer. Although the RV reducer made of aluminum alloy only emerged in 2007. its application field and popularity are even more superior than other types of reducer. It is a kind of reducer with high practicability and a fusion of advanced technologies at home and abroad. NMRV reducer is very convenient to connect with ordinary motor. stepless gearbox and flanged electromagnetic clutch brake set. No coupling is needed. Can be suitable for all – round installation. and the output torque is also relatively large. work fairly smooth and so on.

More on selection of gearboxHow to choose a proper type of Gearbox : It is recommended that as much as possible of the following information be given in the enquiry or order so that a check can be made and advice given on the most suitable size of Worm Speed Reducer for any application. 1.Type of prime mover. 2. Horse-power of prime mover. 3. Output torque required from driven member. 4. Input speed of gear unit. 5. Output speed of gear unit. 6. Configuration of drive required and shaft disposition. 7. Total daily hours of running. If running is intermitte To get the type-choose reference.please contact our technical rep or sales rep .For Good performance of Gear Box. The right selection is very important. The Gear Unit Selection is made by comparing actual transmitted loads with catalogue ratings are based on standard set of load conditions. which invariably changes for different conditions. Therefore service factor must be used to calculate a theoretical transmitted load or equivalent load. before comparing the same. apply the formula : Equivalent Load = Actual Load x Service Factor Mechanical ratings measure capacity in terms of life and / or strength. assuming 10 hours per day continuous running under uniform load conditions. when lubricated with an approved oil and working at a maximum oil temperature of 100°C for normal application lubricant equivalent to ISO VG 320 should be used. When a unit transmits less than catalogue rating. its life is increased. a service factor from Table of Mechanical Service Factor ensure selection of a unit which transmits less than the catalogue rating. its life is thus increased consistent with the increased daily running time. Catalogue ratings allow 100% overload at starting. braking or momentarily during operation. up to 10 times per day. The unit selected must therefore have a catalogue rating equal to. or greater than half the maximum overload. If the unit is subjected to sustained overloads or to shock loads. these must be reflected in the chosen service factor. If overloads can be calculated or estimated then the actual loads should be used instead of a factor. Thermal ratings measure the unit’s ability to dissipate heat. If they are exceeded the lubricant may overheat and break down. with consequent life failure. Both mechanical and thermal ratings are given on next page. Thermal ratings are effected by If the running time is more than 8 hours per day. Mechanical Ratings & Service Factors : Thermal Ratings and Service Factors : ambient temperature and not by mechanical consideration such as increased running time or shock loads. Catalogue ratings assume 20°C running temperature. the oil temperature then rising as the unit transmits power and generate heat. If the ambient temperature is more than 20° C. a lower temperature rise is allowed therefore less power may be transmitted. Similarly in cooler temperatures the thermal ratings may be exceeded. When selecting unit use a service factor from Table of Thermal Service Factor to calculate equivalent loads. For unit sizes 40 to 200. the relevant mechanical and thermal service factors are selected from tables and whichever is higher is applied to find out the equivalent output power and output torque. For unit size 200 to 350. mechanical service factor should be applied to mechanical ratings and thermal service factor should be applied to thermal ratings. Higher of these should be considered for selection of the unit. Thermal ratings assume fan cooling which is standard feature of all Speed Reduction Units. For intermittent running with ample cooling time during rest periods. thermal ratings may be exceeded without overheating and since fan it ineffective. it can usually be removed. It is recommended that as much as possible of the following information be given in the enquiry or order so that a check can be made and advice given on the most suitable size of Worm Speed Reducer for any application.

Materials:cast iron gear case. worm shaft is of Alloy Steel. duly hardened and tempered. The worm wheel is made of Chill Cast Phosphorous Bronze. Fabrication Crafts:liberal ribbing for increasing heat dissipation area. streamlined sump for carrying more oil and fan of ample size which is effective in both side of rotation. Design Standards:We practically apply American.EU.Japan or Indian Design standards .Worm Shafts conform to case- hardening Alloy Steels. Worm Wheels conform to phosphorous-bronze as per BS 1400. While Gear case conforms to C.I. Grade 20. IS210. Other exclusive features :Worm & Worm Wheels: The worm is made of case-hardening / alloy steel. duly hardened. ground and lapped and is integral with the shaft. Bearing journals ate accurately ground. Worm Wheels is made of chill cast phosphorous bronze and tightly fitted with the C.I. Centres. Worm Wheels teeth are generated on precision hobbing machines and high accuracy hobs. Adaptable Worm Gearbox Bearings: The Worm and Worm Wheels are supported on Extra Heavy Duty Tappet roller anti friction bearings of ample margin of safety to allow adequate journals as well as thrust loads. Overhung loads arising Out of sprocket or pinion drive are generally permissible because the gear case and bearing are designed for this duty. In case of heavy overhung load. and extra roller bearing can be provided. Wheel Shafts: The Worm wheel Shafts are made of high tensile carbon steel. duly hardened and ground. It is of large diameter of carry the torsional as well as the bending loads which may be induced by overhung drives. Lubrication: Lubrication in Worm gearbox is by splash of oil from the sump. Thus. no special care is required except for the occasional oil topping of the oil to the required level. An oil filler cum breather plug is provided along with the drain plug and level plug. Oil seals of appropriate size are provided on all input and output shafts.Only For very low input speed of below 50 RPM. and heavy loads in sizes above 350 mm. forced lubrication is required. Worm Gearbox Cooling: Air cooling is effected by means of standard propylene or metal fans which direct air over the ribbed surface of the Case. The fan is designed to operate in both the direction of rotation and is so arranged in conjunction with the ribbing of the case to allow maximum heat dissipation. Overload Ratings: All the Components of the Gear Unit are so designed that they can withstand 100% overload for 15 seconds 50% overload for one minute 40% overload for 15 minutes 25% overload for 1 hour How to choose a proper type of Gearbox : It is recommended that as much as possible of the following information be given in the enquiry or order so that a check can be made and advice given on the most suitable size of Worm Speed Reducer for any application. 1.Type of prime mover. 2.
