Item Description

Rubber wrapping drum is an essential part and component of belt conveying system. The rubber wrapping of the drum can successfully boost the procedure condition of the conveying method, safeguard the metal drum from wear, stop the slip of the conveyor belt, and make the drum run synchronously with the belt, so as to make certain the productive and massive volume operation of the belt. The rubber coating of the drum can also efficiently avoid the sliding friction in between the drum and the belt, decrease the materials bonding on the drum floor, and decrease the deviation and use of the belt. Extensively employed in: Iron and steel, metallurgy, coal, cement, electrical power technology, chemical fertilizer, CZPT depot, port and other industries.

Coating content

Normal rubber, nitrile rubber, neoprene, EPDM, polyurethane, and so on. can be utilised.


There are 2 kinds of rubber wrapping roller technological innovation. The conventional rubber wrapping technology, such as very hot vulcanization technology, mainly vulcanizes its rubber with the roller through the vulcanization tank to make certain the bonding energy amongst the rubber wrapping panel and the roller. The second is cold vulcanization technological innovation, which uses a unique cold vulcanization strategy to immediately bond its roller with the rubber wrapping panel, which can be employed for on-internet site rubber wrapping, underground rubber wrapping, etc, Its technological innovation is far more innovative, but also tremendously minimizes the labor price.

Producing method: usually, in conditions of the primary shaft of the drum, it can be divided into the pursuing 2 varieties according to the load: (1) the mandrel only bears bending moment, such as the shaft of the drum team (2) The CZPT shaft bears bending moment and torque at the exact same time, this kind of as the shaft of the transmission drum team The content of the shaft is usually rolled or forged carbon steel or alloy metal. The typical material is medium carbon metal. No. forty five metal is the most commonly used. For the shaft with massive anxiety and minimal dimension, and some shafts with unique demands, alloy steel can be utilized. The material is forty chromium. In accordance to the requirements, the shaft generally wants heat remedy or floor strengthening remedy, In buy to boost its mechanical qualities and put on resistance, the distinction of elastic modulus among alloy steel and carbon metal is extremely small at standard temperature, so the use of alloy metal can not improve the stiffness of the shaft The shaft material is usually subject to quenching and tempering remedy. For the transmission drum team, when the shaft energy index does not meet the demands, it can also be merged and quenched and tempered, and checked according to the allowable pressure of symmetrical round bending The complex specifications for shell design and style are: (1) when the shell is curled, it must adhere to the rolling course of the steel plate (2) The misalignment at the joint shall not be greater than 1mm (3) Ultrasonic or X-ray flaw detection have to be carried out for the longitudinal weld soon after the drum is coated with glue: ultrasonic flaw detection shall be carried out for ten%, and the weld shall get to grade II in the common Radiographic flaw detection commences from 1 end and detects twenty% of the whole length. The weld reaches grade II of the national standard. If the flaw detection duration is doubled and nonetheless unqualified, entire-size flaw detection shall be carried out till it satisfies the needs (4) The roundness tolerance of the rolled shell shall not CZPT .5 (5) Materials: Q235 area steel with yield energy of 235 n / m2 For medium-sized drum group and gentle-obligation drum team, when the outer diameter of the hub is higher than 220mm, forged metal shall be utilised. For mild-responsibility drum group, when the outer diameter of the hub is less than 220mm, sizzling-rolled spherical metal shall be utilized, which shall fulfill the national common.


A rack is a portion of a cylindrical disk with an infinite radius, the floor of which is lower with involute teeth. The racks are exclusively mated to spur gears with the same module, pressure angle, and preferred confront width. EP gives racks in a selection of components, configurations, modules, and lengths. A special feature of our racks is that most of them appear with concluded items. This type of creation allows numerous racks to be connected stop to conclude to make a constant duration of racks. A lot of of our offerings allow for secondary operations this kind of as shortening lengths, adding threaded holes, or making use of heat treatment method. Our products also incorporate goods that have accomplished some of these secondary functions.
There are numerous sorts of gears, and the most frequent classification strategy is by gear shaft. Typically, there are 3 kinds of the parallel axis, cross-axis, and staggered axis. 1) Parallel shaft gears: like spur gears, helical gears, internal gears, racks, and helical racks, and so forth. 2) Cross shaft gears: straight bevel gears, spiral bevel gears, zero-degree bevel gears, and so on. 3) Staggered shaft gears: There are staggered shaft helical gears, worm gears, hypoid gears, and so on.
