Description
Technical field
The invention belongs to ribbon conveyer tranmission techniques field, relate to a kind of contact sealing nylon carrying roller of adjustable bearing split bearing pretightning force.
Background technology
Ribbon conveyer is the capital equipment transporting continuously in fields such as metallurgy, mine, chemical industry, harbour, building materials. Carrying roller distributes along ribbon conveyer total length, and its gross weight accounts for 30%～40% of complete machine, is worth and accounts for 20% of complete machine. Carrying roller is vitals and the consumable accessory on ribbon conveyer, and its quality directly affects runnability and the safety of conveyer. The maintenance cost of carrying roller is the chief component of ribbon conveyer running cost, and rubber conveyer maintenance workload 80% be change carrying roller.
Steel carrying roller own wt is greatly, not corrosion-resistant, waterproof effect is poor, under coal mine under trickle or humidity, corrosive environment, and the shortcomings such as working life is short, conveyer energy consumption height. Along with rubber conveyer is to the at a high speed development of (being increased to 4.5m/s by 2.5m/s), large conveying quantity and long haul distance direction, carrying roller is also proposed to new requirement: at a high speed, heavy duty, long-life. But by the research of domestic rubber conveyer service condition is found, the average life of domestic carrying roller is far below projected life (30,000～50,000h), generally at 8000～10,000h. Transform traditional carrying roller, have: " a kind of high molecular plastic carrier roller " application number 201020212745.1, publication number CN201670549U, its quality is light, corrosion-resistant, but it is, in bearing block outer face, ring-type bulge loop is set, ring-type bulge loop coordinates with the cannelure of offering on roll body inwall, give like this inconvenience is installed, after long-term operation, bearing block is rotated along roll body, well fixed bearing block. " coal mine under-well plastic roller " application number 200920024488.6, publication number CN201406197Y, it carries out axial restraint with outer back-up ring to sealing ring, sealing ring is directly exposed to outside, easily contact with larger coal cinder, sealing property is bad, easily occurs stuck phenomenon. " nylon carrying roller " application number 200920282916.5, publication number CN201678269U, its bearing block the inside does not have sealing device, but by the seal cover of bearing block outer face, the indoor bearing of bearing block is sealed, moisture can directly enter in bearing block in a humid environment, corrode bearing, sealing effectiveness is poor. " a kind of carrying roller " application number 200910064235.6, publication number 101804905A, on its bearing block, edge is with the flange of location, but the contact area of this bearing block and roll body is larger, erection stress is large, and it does not have anti-sticking back-up ring, make the windrow on ribbon conveyer side cause damage to bearing block inside, reduce the life-span of carrying roller.
And the carrier roller of belt conveyer that China is generally used uses steel carrying roller more, steel carrying roller exists in the mill certain structures design and is difficult for processing, is restricting the employing of new construction, and is restricting to a certain extent the development of rubber conveyer. Compared with same kind of products at abroad, due to the usage quantity of carrying roller and the huge property that consumes the energy, extremely urgent to the transformation of carrying roller. Invent a kind of contact sealing nylon carrying roller of adjustable bearing split bearing pretightning force, to be extremely necessary having extremely important meaning the service life of improving carrying roller for this reason.
