Product Description

Brief introduction to our company

Chengke was established in 2000, 15 years of designing and manufacturing experiences in material handling industry. Now we have 100 - 200 full time employees, Registered Capital: RMB 30,000,000, we have 3 subsidiaries: one is specialized in providing dust removal solutions to customers and the other is dedicated in supplying conveyor maintenance tools and the third is specialized in developing status and temperature monitoring products. We have more than 30 engineers and have passed ISO9001:2008 certification in 2012 and obtained CE certificate for belt conveyor system. It takes only 1 hour from our company to Tianjin port and 30min to Beijing.

Samples are acceptable. Rush order and large quantity are acceptable. 

Belt Conveyor Pulley, Pulley
CK pulleys can be divided into three categories based on different load: light type, normal type and heavy type. Large torque pulley is made from the turbine and cast welded steel structure. The connection between pulley and shaft can be key jointed structure or distensible cover structure which will profoundly reduce the total weight of the pulley and shaft weight and can be disconnected easily.

Belt Conveyor Pulley, Pulley
CK pulley adopts the CO2 gas shielded welding and submerged arc welding, and the welding seam is inspected by ultrasonic and X-ray. The surface of CK driving pulley is vulcanized with herringbone and argyle rubber lining. Before shipping, the pulleys need to take static balancing test to get minimum rotary resistance. The bearing house of CK pulley is the split structure which ensures its simple maintenance. 

 Driving pulley

Driving pulley is the main part to convey driving force. CK driving pulley is divided into light sized, middle sized and heavy sized pulley. The diameter varies  from 500mm, 630mm, 800mm, 1000mm, 1250mm, 1400mm, 1600mm.We can provide different shaft diameter under the same pulley diameter for users and designers. CK pulley is available for the range of B=500-2400 and the resultant force rang from 5KN to 1650KN.

-- Light sized: the shaft diameter is 80-100mm. The shaft and hub is single plate welded structure connected by single key, and the shaft can be extended outside the shell in one end.
--Middle sized: the shaft diameter is 120-220mm. The shaft and the hub are connected by keyless locking device.
-- Heavy sized: The shaft diameter is 200-400mm or larger. The shaft and the hub are connected by keyless locking device. The pulley is cast welded structure. There are two types: the single end extended shaft and two end extended shaft.

The driving pulley surface is bold steel and can be casted with herringbone and diamond rubber lagging.

Bend pulley

 Bend pulley is used to change the direction of conveyor and increase the surrounding angle between the belt and driving pulley. Same with driving pulley, CK bend pulley is also divided into light sized, middle sized and heavy sized according to its carrying ability. The diameter division is 50-100mm, 120-220mm and 200-400mm. It has the  same structure with the driving pulley. Its surface also has the cover of bold steel, herringbone rubber, diamond rubber and smooth surface vulcanized rubber.

  The bend pulley is used to change the operation direction of belt. It should be placed on the tail end or take-up device when changing the direction with 180°while placed on the upper side of the take-up device when changing the direction with 90°.Surface-increased pulley is generally used to change direction with less than 45°. Bend pulley can be selected according to belt width and resultant force.

Pulley production techniques

CK pulleys are manufactured by strictly implementing the following steps:

--Cutting: The light tracking cutting machine ensures cutting accuracy.

-- Welding: CO2 gas shielded welding and submerged arc welding guarantee the reliable quality.

--Non-destructive testing: The welding seam will undertake non-destructive testing by ultrasonic and X-ray to ensure the welding quality.

--Annealing: Annealing treatment should be taken to eliminate the internal force.

--Static balancing: Static balancing test should be taken after assembling to ensure pulley's service life.

--Vulcanized rubber casting: All the pulleys should take vulcanized rubber. We have professional vulcanized workshop, equipment and technology. Besides we are equipped with special devices specializing in cutting herringbone and argyle pattern. They can secure us to provide high level precision pulley: the excircle runout displacement is less than 0.2mm (Better than the required 0.5mm for high quality products in national standard).
