Description
Technical field
The present invention relates to a kind of line belt and belt wheel, particularly a kind of special conveyer belt and belt wheel that is used for pumping unit.
Background technique
Used for oil extractor belt of the prior art nearly all is the infantees band, lean on friction driving between band and the belt wheel, particularly two belt wheels are bigger frequently for the two diameter that slows down, small pulley is a driving wheel, big belt wheel is a follower, the cornerite of big belt wheel is far longer than the cornerite of small pulley, thereby causes the small pulley skidding very general, and sleety weather is particularly serious.Skid and cause belt wearing and tearing aggravation, skid and cause pumping unit idle running, oil recovery efficiency reduces even the stopping production of recovering the oil greatly.Operating characteristic at the synchronous band of pumping unit.How this patent prevents the small pulley problem of skidding with regard to main research.The solution problem the best way that skids is to adopt engagement driving just to come transmission with sprocket wheel, but, sprocket driving only is applicable under the state of low speed transmission, and, sprocket driving is not a kind of transmission stably, the caused vibration of the moment impact of chain between sprocket wheel is enough to cause the chatter of whole pumping unit, and this is fatal to pumping unit.Because the counterweight of the kowtow part (pumping unit is commonly called as the machine of kowtowing) and the both sides of pumping unit is very heavy, little by little vibration is enough to cause big accident.In view of this, we have vetoed sprocket driving.
Chinese patent publication number CN2804496 discloses a kind of belt of oil pumping machine cornerite controlling device, and by motor pulley, oil pumping unit base, cylinder, support, belt, speed reducer belt pulley are formed.Motor pulley is installed on the pumping-unit motor output shaft, the speed reducer belt pulley is installed on the oil pumping unit reduction gearbox input shaft, belt is installed on motor pulley and the speed reducer belt pulley, support is installed on the oil pumping unit base, cylinder is rack-mount, cylinder is pressed in the belt top, make the belt top bending occur, thereby increase belt through distance, increase belt tightening, increase belt at motor pulley, cornerite on the speed reducer belt pulley, make belt and motor pulley, do not occur skidding between the speed reducer belt pulley, the oil well pump jig frequency of oil well can not reduce, and can not influence oil well output, can not cause oil well to stop production yet, avoid economic loss because of belt slippage causes the scaling loss of belt.The disclosed belt of oil pumping machine cornerite of this utility model patent controlling device, say from the side and solved pumping unit to a certain extent in the running, all adverse consequencess that can prevent belt slippage and cause, cause economic loss, but load the belt contact controlling device and can not fundamentally solve the pumping unit skidding, controlling device itself is also damaged easily, loading adjusting device is on belt, the stationarity of belt is affected, the curvature of belt is constantly changed, cause the shakiness that passes band, also make belt aging easily simultaneously, reduce the life-span of using.
Summary of the invention
The technical issues that need to address of the present invention are, overcome the deficiencies in the prior art part, provide a kind of novel structure simple, easy to use, can fundamentally solve pumping unit belt slippage phenomenon in the running, guarantee the normal operation of pumping unit to a great extent, prolonged the working life of belt synchronously.
The objective of the invention is to be achieved through the following technical solutions:
A kind of special conveyer belt and belt wheel, comprise line belt and belt wheel, described line belt comprises viscose and core rope, described line belt is provided with profile of tooth, described belt wheel is provided with pulley groove, is provided with recessed tooth in the described pulley groove, and the profile of tooth on the described line belt is meshed with pulley groove concave tooth, described line belt and belt wheel are complementary, and line belt rotates with the rotation of belt wheel.Belt wheel described here is the small pulley in the pumping unit, drives big belt wheel by small pulley by line belt.The present invention's line belt and the engagement driving between the belt wheel are had a few similar in appearance to the engagement driving between synchronous band and its belt wheel, but are different from the engagement driving of synchronous band.Band transmission synchronously is a kind of motion of precision, and the rotating ratio between two belt wheels is constant, does not allow to change; Therefore, with two wheels of transmission tooth is arranged all synchronously.And the present invention's transmission is power and moment, to big belt wheel, big belt wheel is rotated power on the small pulley and transmission of torque as long as can take care of yourself, unimportant as for the rotating ratio between big belt wheel and the small pulley, therefore, big belt wheel is unnecessary is with recessed tooth, does not also just need the accurate requirement of band synchronously.Moreover, if the words that big belt wheel designs by the requirement of synchronous band, the increase of cost also is unacceptable, both made big belt wheel make synchronous band belt wheel still more, synchronous band so long and so big specification also can't move, because the elongation percentage of so long band synchronously is for a long time considerably beyond the necessary lit range of synchronous band precision.The present invention has been designed to recessed tooth with small pulley, and big belt wheel is still kept intact.Power that small pulley will transmit and moment are still transmitted by friction, and the designed recessed tooth of small pulley only only limits to anti-skidding.In order to prevent that the climbing tooth phenomenon that synchronous band is occurred from taking place, when the flute profile design of band between profile of tooth and the recessed tooth with tangent line excessively to guarantee the steady of transmission.Because line belt and big belt wheel and follow small pulley in conjunction with the time curvature different, so when line belt moved between belt wheel, the curvature of line belt was constantly changing.Basically the curvature that is in operation of line belt has three kinds of forms, and a kind of is and big belt wheel binding portion that a kind of is and the small pulley bound fraction to be exactly the straight portion between the two-wheeled in addition.Since line belt during fabrication profile of tooth and the flute profile of the recessed tooth of small pulley guarantee by mould, can the manufactured place very accurate, but when operation its in its curvature of different positions all among the variation that does not stop.Line belt is a rubber material, because the tooth that the straight portion between big belt wheel and two-wheeled does not match with line belt so the flute profile on its line belt changes not influence of operation, has just improved the degree of deflecting of line belt.And the recessed heel of small pulley transmits and has the engagement requirement, promptly is exactly that to require small pulley and line belt to mesh as much as possible smooth and easy, and climbing tooth is not interfered.But in engagement driving particularly the flute profile of line belt always among the variation that does not stop, climbing tooth and not interfere almost be impossible not.Adopted two kinds of ways to solve this problem.The one, thus when line belt and small pulley design, line belt and small pulley are designed to the circle-arc tooth assurance when climbing tooth takes place with interference, and climbing tooth between line belt and the belt wheel and interference impact are as much as possible little and can justify excessively suitable; The 2nd, both made and climbing tooth taken place and interfere to drop to minimum because the resiliently deformable of line belt self is impacted motion, thereby and since big belt wheel be anodontia when small pulley generation climbing tooth and when interfering big belt wheel line belt partly little slip can take place and automatic deviation correction makes small pulley recover normal operation.Because the diameter of big small pulley is bigger than very, the angular velocity of small pulley is more much bigger than the angular velocity of big belt wheel, so the big slight slip of belt wheel is enough to allow the climbing tooth of small pulley and interference obtain correcting.And the slight slip of big belt wheel can't have any influence to the oil pumping action of pumping unit, skidding can not occur thereby make line belt understand the problem that takes place at the volley.Thereby the major function of flute profile of the present invention is to prevent skid on the small belt pulley smooth transmission of assurance power and moment of line belt.The main stress surface of line belt still on two V faces of line belt, the profile of tooth of line belt want the least possible stressed be purpose so that it is skidded on small pulley.Therefore, the degree of wear of line belt is reduced to minimum and is made the life-span of belt reach the longest, at first make the flute profile of small pulley and the flute profile of line belt want enough engagements in order to make small pulley, between the two excessively want enough steadily and smooth and easy; Secondly, the small pulley flank of tooth wants enough smooth to reduce the wearing and tearing to line belt; Moreover, the convex and concave teeth of small pulley and the profile of tooth of line belt nibble with the time also enough heat-dissipating spaces to be arranged so that the distributing and transmitting of heat.In order to guarantee the degree of finish on belt wheel surface, adopt and be processed as the higher material of surface finishment easily, as iron and steel, aluminum alloy, Cuprum alloy, magnalium etc.The profile of tooth of line belt described here is an axial tooth profile, and in the last radially profile of tooth that is provided with, the convex and concave teeth in described profile of tooth and the small pulley in the pulley groove is meshed at axial tooth profile.
