Abstract
The utility model discloses an oil-free oscillating type driving device for an air compressor, which comprises a crank and connecting rods, wherein the crank driven by a driving wheel is symmetrically provided with a front crankthrow type crankshaft and a rear crankthrow type crankshaft, on which a pair of connecting rods are arranged respectively, the connecting rod adopts a split type, the hole of the connecting rod is internally provided with a rolling bearing, and two rolling bearings are respectively connected on the front crankthrow type crankshaft and the rear crankthrow type crankshaft. The oil-free oscillating type driving device for the air compressor has simple structure, is convenient to use and easy for detachment and installation, and is used for discontinuous transportation, loading and unloading of granular and powdered matters.
Description
Technical field
The utility model relates to the air compressor field of components, particularly relates to a kind of transmission device that does not have oily swing type air compressor.
Background technique
The transmission device of the nothing oil swing type air compressor that former cement bulk is automobile-used all adopts single connecting rod bearing shell formula (singly turning connecting rod), mainly by connecting rod, bent axle, connecting rod shank bearing housing, bearing shell, oil pump (lubricating) gear, parts such as umbrella gear are formed, and by prime motive power drives such as motor car engine or motor, drive bent axle through belt, connecting rod makes swing-rotor do swing repeatedly in cylinder, produces working force.The bent axle of this kind transmission device and bearing shell are by the oil pump oil injecting lubricating, and oil pump connects power by gear, umbrella gear again and could work.The defective of this device is: the sliding bearing friction area is big, and the working environment of high temperature and high speed can only continuous operation≤60 minute, and operating time long slightly very easily " tile kilning " and noise are big, and power consumption is big, and vibrations are big, poor work stability; Because of lubricating pump can only be given the bearing shell oiling when just changeing, thereby this transmission device can only just change, and can not reverse, and is restricted thereby install and use all; Lubricated many with the pump work link, arbitrary link goes wrong, and causes lubricant oil fuel feeding undesired moment will cause device damage; While, when using the parallel bars malaria, to a direction swing, driving mechanism strength imbalance, fortune grade load in a state of excitement were big simultaneously, cause and shake and shorten the working life of each parts easily at single connecting rod bearing shell formula transmission device.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, discloses a kind of transmission device that does not have oily swing type air compressor.Replace sliding bearing with rolling bearing, need not oil pump and relevant gear, umbrella gear transmission part, use stablely, balance is good, increases the transmission device of the nothing oil swing type air compressor in parts working life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of transmission device that does not have oily swing type air compressor, comprise crankshaft-and-connecting-rod, described bent axle is by drive wheel, crank shaft and after crank axle before on bent axle, being symmetrical arranged, pair of links is separately positioned on preceding crank shaft and the after crank axle, described connecting rod is split type connecting rod, and rolling bearing is housed in the tie rod holes, and 2 rolling bearings are connected on preceding crank shaft and the after crank axle.
The further improved technological scheme of the utility model is:
Described bent axle is that split type hyperbolic turns bent axle, is connected with nut by crank throw, tapering axle, hole, key to combine.
The beneficial effects of the utility model are:
Rolling bearing is set than sliding bearing (bearing shell) between crankshaft-and-connecting-rod, friction area is little, and greasy property is good, thereby can reduce air horsepower by a relatively large margin, reduces noise and obviously prolongs stream time.Because adopt double link, hyperbolic turns bent axle, when work, make two malarias swing round about simultaneously of air compressor, make its driving force keep balance, running is stable, impulsive load is little, effectively prolongs the working life of each parts, and reduces the rate of fault of parts.Owing to remove lubricating pump, motive force is not limited by forward and backward, installs more conveniently, can the simplified apparatus structure reduce product cost again, minimizing equipment operation fault.Bent axle is taked compound mode, for convenience detach and assembling, and the while also is convenient for changing the assembly of damage, more meets economical and practical principle.In sum, the utility model is simple in structure, and is easy to use, is convenient to dismantle, installs, is used for granular, and powder-shaped matter is interrupted the conveying of operation and the air compressor transmission device of loading and unloading.
Description of drawings
Fig. 1 is the structural drawing of the transmission device of no oily swing type air compressor described in the utility model;
Fig. 2 is a linkage plane view described in the utility model.
The division mark is as follows among the figure: 1, bent axle; 2, connecting rod; 3, preceding crank shaft; 4, after crank axle; 5, rolling bearing.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined purpose is taked, and below in conjunction with accompanying drawing and preferred embodiment, is described in detail as follows.
Mode of execution one
A kind of transmission device that does not have oily swing type air compressor, comprise bent axle 1 and connecting rod 2, bent axle 1 by drive wheel, crank shaft 3 and after crank axle 4 before on bent axle 1, being symmetrical arranged, pair of links 2 is separately positioned on preceding crank shaft 3 and the after crank axle 4, described connecting rod 2 is split type connecting rod, 5,2 rolling bearings 5 of rolling bearing is housed in the hole of connecting rod 2 is connected on preceding crank shaft 3 and the after crank axle 4.When mounted, pair of links 2 is connected respectively with malaria on the cylinder body, is used to drive the malaria piston motion, one of bent axle 1 connects driving wheel, the other end is fixed on the compressor, when running, and drive wheel bent axle 1, bent axle 1 drivening rod 2, connecting rod 2 drives malaria, owing to adopt hyperbolic axle 1, hyperbolic turns bent axle, when work, make two malarias swing round about simultaneously of air compressor, make its driving force keep balance, running is stable, impulsive load is little, and take rolling bearing 5 to replace sliding bearing in the existing design, this will reduce the parts of transmission device, these parts of minimizing lubricating pump, more reasonable structure is used more convenient.
Mode of execution two
On the basis of mode of execution one, the utility model is further improved, described bent axle 1 turns bent axle for split type hyperbolic, and bent axle 1 is connected with nut by crank throw, tapering axle, hole, key and combines.Bent axle 1 is taked compound mode, for convenience detach and assembling, and the while also is convenient for changing the assembly of damage, and the upgrading of mode of execution one just of split type double throw structure can further be optimized the transmission of power, energy saving simultaneously.
In sum, the utlity model has above-mentioned plurality of advantages and use value, no matter it all has bigger improvement on product structure or function, obvious improvement is arranged technically, and produced good and practical effect, the market demand that meets multifunctional all really is a new and innovative, progressive, practical new design.Easy-to-operat, practical safety, advantage such as cost is lower is convenient to promote and is made, and has wide market application prospect.
Obviously the foregoing description is not to restriction of the present utility model, and above-mentioned a kind of transmission device that does not have oily swing type air compressor can also have other many variations.Though gone through the utility model in conjunction with above-mentioned example, some that should be understood that professional person in the industry can expect apparently are identical, and alternative scheme all falls within the protection domain that the utility model claim limited.
