Simple in structure, the advantages such as bearing capacity strong, reliable operation that crank slide bar (piston) mechanism has, but there are the deficiencies such as quickreturn characteristics, transmission efficiency be lower in crank slide bar (piston) mechanism, its stroke increase also is very limited, increase stroke such as need, will increase in proportion the length of the turning radius and the slide bar (piston) of crank, the result will cause the rapid increase of complete machine weight, and the series of problems such as manufacturing cost, impact transportation and installation occur increasing considerably.
The cam sliding bar mechanism is higher pair mechanism simple in structure, the shortcoming such as exist that stroke is short, serious wear, transmission efficiency are low, and the main machinery that transmits smaller power of using is such as the gas distribution system of internal-combustion engine etc.
Pinion and rack has that proportioning is free, easy to manufacture, bearing capacity is strong, mobile steadily, not advantages of higher of Location accuracy is installed, in modern mechanical, be used widely.But gear rack wearing and tearing easily occur and needs compensation, its stroke size also to be subject to certain limitation.
Machining accuracy and the positioning requirements of bolt and nut (ball screw) mechanism are higher, need the positive and reverse return of power engine to transfer realization and cause transmission efficiency low, also have little, the easy appearance wearing and tearing of bearing capacity and the shortcomings such as needs compensation.
Linear electric motor mainly are used on the high-precision machine tool, and its outside supporting electric control system is too complicated.There is frequent starting in the linear electric motor that are used for reciprocator, and inrush current is several times as much as normal running current, so that the shortcoming such as the large and transmission efficiency of copper loss iron loss consumption is low.
In oil exploration equipment pumping unit the inside, existing with the key technology of tooth-gear teeth bar as linear shuttle mechanism, find in actual use that still the machining accuracy of gear-tooth bar and difficulty are higher, need special purpose machine tool to make, so that cost of production is larger; Equally harsher to lubricated requirement, in case a certain gear teeth fracture on the tooth bar, whole tooth bar all must be scrapped, so that maintenance cost increases and practical application is promoted and received very big restriction.
The model utility content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existing equipment, provide a kind of simple in structure, cost is low, convenient for installation and maintenance, reliability is high, bearing capacity is strong, smooth running, transmission efficiency is high, volume is little, stroke is large linear shuttle mechanism, to satisfy the mechanically operated needs of some linear reciprocation.Innovation of the present utility model is to realize first sprocket wheel
-The outer kneading of chain, and further brought into play sprocket wheel
-The functionality advantage of chain.
The technological scheme that the utility model adopts to achieve these goals is as follows:
A kind of sprocket wheel-chain type linear shuttle mechanism is characterized in that comprising frame, slide block, sprocket wheel and slide rail; Described slide block up and down two ends all is provided with the guide pad that turns to for the control sprocket wheel; Described frame two opposite sides inner chamber is provided with parallel chute, described slide block is assemblied between two chutes on the frame and along chute and pumps, and be installed with ring chain on the slide block, described slide rail is fixed on the frame and with chute and is the space criss-crossing, described sprocket wheel is assemblied on the slide rail and along the to-and-fro motion of the slide rail left and right sides, and sprocket wheel and chain remain outer gearing.
The technological scheme that is more preferably in the utility model is: this mechanism also comprises a power mechanism, this power mechanism connect sprocket wheel and with the sprocket wheel synchronizing moving, described power mechanism is made of motor and retarder, the output shaft of retarder connects sprocket wheel, motor and retarder are fixed on the connecting bottom board, the lower surface of connecting bottom board is provided with two upper rails, also is provided with the lower rail that is fixed on the frame and intersects with two upper rails under the connecting bottom board, and two upper rails are connected with lower rail by pulley.
The technological scheme that is more preferably in the utility model is: described two guide pads are the semicircle arcuation, and chain is fixed on the slide block by two chain stretching devices that are fixed on the slide block; And chain is welded on the chain stretching device at two ends up and down, and this chain stretching device is helical or wedge shape.
The utility model adopts chain to substitute the card article transmission, so transmission is more accurate, structure is compact, do not need very large tension force, and the load that acts on the axle is less; Be not afraid of greasy dirt, can adapt to the wild environment demand.And sprocket wheel-chain only need be purchased professional makers' standard piece and get final product.Aspect impact resistance, sprocket wheel-chain has more impact resistance, even a certain chain link failure on the chain also only need only be changed impaired chain link, safeguards more convenient.Aspect impact resistance, sprocket wheel-chain has more impact resistance, even a certain chain link failure on the chain also only need only be changed impaired chain link and get final product, therefore safeguard more convenient.Aspect the increase length of stroke, sprocket wheel-chain also has more competitive advantage than gear-tooth bar, and stroke is longer, and the difficulty of processing of tooth bar is more remarkable, and the assembling of chain is subjected to the restriction of long stroke not obvious.
Therefore the utlity model has simple in structure, cost is low, convenient for installation and maintenance, high reliability, also has the characteristics such as bearing capacity is strong, smooth running, transmission efficiency is high, volume is little, stroke is large.Be a kind of superior performance, be widely used, have the linear shuttle mechanism of significance of times, can be widely applied in industries such as lathe, lifting machine, internal-combustion engine, plunger pump, petroleum beam-pumping units.
