Description
Technical Field
The utility model relates to a conveyor means especially relates to a novel conveyer belt of off tracking is prevented to resistance to deformation.
Background
In modern production processes, various conveyor belts are used to increase production efficiency. The conveyor belt is often used for machine transportation in modern industry due to its high efficiency, short path, and high mechanical properties. Meanwhile, the conveyor belt conveyor is continuously perfected under the influence of technical progress of mechanical manufacturing, motors, chemical industry and metallurgical industry, and becomes an indispensable component part for mechanization and automation of a material handling system. Different transmission devices can be divided into friction transmission, meshing transmission, traction transmission and the like according to a transmission mode; they can also be classified into rigid belt drives, gears, chains, tape drives, etc. according to the components of the drive.
A new metal belt was designed and published in 3 rd volume, journal of agricultural machinery, 31 st date. It combines three transmission modes, namely gear, adhesive tape and chain transmission. It is composed of engaged tooth profile and metal thin band with engaged hole, and its transmission structure is very simple. It has absorbed chain drive and sticky tape transmission's advantage: the metal teeth are meshed with the high-power transmission characteristic and the continuous flexible process of the contact of all the non-tooth parts with wheels and belts is realized; a large center distance transmission shared by the two is provided; the extremely unstable and polygonal effects generated by the rigid motion of the chain in the chain transmission are overcome; meanwhile, the problem of slippage caused by obvious elastic sliding and large power in the transmission of the adhesive tape is solved.
However, the metal rigid belt transmission also has a plurality of problems during the use process, namely deviation. The deviation of the strip steel is extremely harmful, the quality of the strip steel is influenced, even serious damage to the whole production equipment can be caused, the safety of a production line is influenced, and the reliability of the production line is reduced. When the metal belt is operated in a normal state, the longitudinal center lines of the metal belt and the wheel must be coincident, and the rotation direction of the circumference of the wheel is consistent with the speed direction of the metal belt. Otherwise, the deviation phenomenon will occur. The metal belt is deviated mainly for two reasons:
(1) with parallel pulley axes, maintaining the running track of the metal belt may be more difficult than other types due to the quality of the belt. This is because the metal strip cannot rely on elongation to compensate for system non-flatness or misalignment, uneven loading and strip beading. Crimping means that the edges of the belt are not straight but curved, so that the belt may be tapered, and when the belt is placed on a straight two-wheel system and tensioned, one side of the belt is tensioned more than the other side due to the shorter length of the belt. When the belt is driven, the running track of the belt moves from the more tightly tensioned side to the more loosely tensioned side.
(2) Slack-side tightness also occurs when the belt is straight and the dual wheel axes are not parallel.
In addition, steel belts often suffer from deformation wear. If the meshing type transmission is used for overcoming the deviation problem, although the meshing bulges are arranged on the wheels and the meshing holes are arranged on the belt, the belt can be prevented from falling off due to deviation, the metal belt can be seriously abraded due to compression deformation, simultaneously, great noise can be generated, the belt can be seriously torn due to local stress concentration, and the service life of the belt can be seriously influenced.
