According to the cross shaft type universal coupling, the problems that in the prior art, a cross shaft is prone to breakage, the roots of a fork are prone to cracking are solved.
Description
Technical field
The present invention relates to field of mechanical technique, be specifically related to universal coupling with spider.
Background technique
Universal coupling with spider is a kind of the most frequently used coupling.Utilize the feature of its structure can make comparatively not large at same axis or axis knuckle or move axially larger diaxon isogonism speed continuous rotary, and reliably transmitting torque and motion.Transmitting torque in the mechanical axis system of lifting, engineering transportation, mine, oil, boats and ships, coal, rubber, papermaking equipment and other Heavy duty maching industry can be widely used in.
The main feature of universal coupling with spider is: 1. have larger angle compensation ability.2. compact structure is reasonable.SWC-BH type adopts integrated type jaw, makes delivery have more reliability.3. bearing capacity is large.Compared with the shaft coupling of other pattern identical with swing diameter, its moment of torsion transmitted is larger, and this is to the restricted machinery of swing diameter, and its supporting scope has more superiority.4. transmission efficiency is high.Its transmission efficiency reaches 98-99.8%, and for high-power transmission, energy-saving effect is obvious.5. steadily, noise is low, installs and removes easy to maintenance in delivery.
Universal coupling with spider allowable rotating speed scope is that to adjust two shaft assignment more difficult for the linear velocity that allows according to Hooks coupling universal coupling different materials and heavy-duty machines equipment, reduces shaft part stress due to torsional vibration.Can absorb and reduce the fluctuation of diesel engine Driving Torque, for the diesel power plant that reduction gear box is housed, when can reduce variation torque, face of gear be knocked, answer choice for use durable and change easily damaged parts coupling easily.Metallic elastic unit property flexible coupling is generally than the long service life of non-metal elastic element flexible coupling.Need seal lubrication and use non-resistant universal coupling with spider, must maintenance workload be increased.For the occasion operated continuously for a long time and economic benefit is higher, industrially developed country in the world, the common diaphragm shaft coupling suitable replacement drum-shaped tooth type shaft coupling selected long service life, need not lubricate and safeguard, not only increases economic benefit, also can purify working environment.There is good damping vibration attenuation characteristic, can absorption portion vibrational energy, be reduced by vibration amplitude when to shake, extend service life of gear.
The universal coupling with spider of prior art has following shortcoming: cross axle easy-rupturing, and jaw root easily occurs crackle.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, the universal coupling with spider that a kind of structure is simple, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution used in the present invention is: it comprises left half-coupling, right half-coupling, knuckle joint; Described left half-coupling is connected by knuckle joint with right half-coupling; Described knuckle joint is formed by connecting by two cross-axle universal shaft joints; Described cross-axle universal shaft joint comprises cross axle, pin, sleeve, straight pin; Be inserted with sleeve in the vertical center hole of axle journal of described cross axle, in sleeve, be inserted with pin, in the axle journal horizontal centre hole of cross axle, be inserted with straight pin; The adjacent axle journal root of described cross axle becomes arc-shaped, and the wall thickness between the axle journal of cross axle and center hole is 15 ~ 25mm.
As preferably, described cross axle adopts 40Cr cross axle, and adopts heat treatment process, and hardness is 58 ~ 62HRC.
As preferably, described left half-coupling and the joint of right half-coupling and knuckle joint are provided with circular arc gusset.
When the present invention operates, because crackle root and breaking part all occur from the knuckle of axle root, so stress is herein comparatively concentrated, stress distribution gradient is large, the arc-shaped of neck root and the wall thickness between the axle journal of cross axle and center hole design make axle root concentrated stress value reduce, and cross axle stress distribution is comparatively balanced; The design of circular arc gusset makes the part stress concentrated seamlessly transit, and strengthens knuckle joint and the bearing strength between left half-coupling and right half-coupling.
After adopting said structure, the beneficial effect that the present invention produces is: universal coupling with spider of the present invention, solve the cross axle easy-rupturing of prior art, problem that crackle easily appears in jaw root, the present invention have structure simple, arrange rationally, the advantage such as fabricating cost is low.

Embodiment
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Referring to such as Fig. 1---shown in Fig. 2, this embodiment adopts following technological scheme: it comprises left half-coupling 1, right half-coupling 2, knuckle joint 3; Described left half-coupling 1 is connected by knuckle joint 3 with right half-coupling 2; Described knuckle joint 3 is formed by connecting by two cross-axle universal shaft joints; Described cross-axle universal shaft joint comprises cross axle 4, pin 5, sleeve 6, straight pin 7; Be inserted with sleeve 6 in the vertical center hole of axle journal of described cross axle 4, in sleeve 6, be inserted with pin 5, in the axle journal horizontal centre hole of cross axle 4, be inserted with straight pin 7; The adjacent axle journal root of described cross axle 4 becomes arc-shaped, and the wall thickness between the axle journal of cross axle 4 and center hole is 15 ~ 25mm.
