Abstract
An open joggled shaft coupling relates to the single engagement tooth type shaft coupling of the flexible shaft coupling, belonging to the shaft coupling technique field, which is used in resolving the question that the shaft coupling has short service life and is easy to hit tooth in hostile environment, comprising a left, a right back-rest wheel and a counter shaft, the counter shaft is engaged with the left or the right back-rest wheel, which is improved that the counter shaft is engaged with the left or the right back-rest wheel via the spline tooth, the outer circumference of the counter shaft is provided with a spline tooth 4', the outer end face of the left or the right back-rest wheel is provided with a spline tooth 4, the spline tooth 4' and the spline tooth 4 is engaged with each other and socket mesh. The utility model employs the open spline tooth to expose the inner and the outer gear wheel originally concealed inside, and correspondingly extends the tooth shape section, because the engaged socket spline tooth basically has no relative slide, which can normally and reliably work under the unlubricated condition, greatly improve the reliability of the shaft coupling working and the service life, which has the advantages of high temperature resistance, water flush resistance, high bearing capacity, convenient observation and maintenance and the like, and is applicable to use in hostile working environment.
Description
Technical field
The utility model relates to the single engagement gear coupling in the flexible coupling, belongs to the coupling technical field.
Background technique
Single engagement gear coupling is made up of left and right clutch, jack shaft etc., internal gear in external gear on the jack shaft and the clutch is meshed, two transmission shafts are connected with another backrest with jack shaft respectively, be connected by bolt between the left and right clutch, allow the relative displacement within the specific limits of two transmission shafts, have very high bearing capacity.The inside and outside gear that is meshed in this kind coupling is hidden in clutch, need lubricate during work.When coupling is in the abominable working environment, as at high temperature, high dust and have cooling and splash when working under the environment of current, hiddenly sharply worsen at interior engaging tooth lubricating status under rugged environment, engaging tooth wearing and tearing aggravation, coupling shortening in working life, can occur continually beating the tooth accident, influence the normal operation and and then the influence production of equipment.Simultaneously, also can cause maintenance load and the big good fortune degree of spare parts consumption to rise because of overhauling, change coupling continually.The problems referred to above performance in the use of equipment such as steel rolling cooling chain bed is particularly outstanding, for guaranteeing the normal operation of manufacturing mechanism, must improve above-mentioned coupling.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of open type engagement coupling that overcomes above-mentioned use defective, reliable operation.
The alleged problem of the utility model realizes with following technical solution:
A kind of open type engagement coupling, left and right clutch and jack shaft are arranged in the formation, a jack shaft and a left side or right clutch are meshed, its improvement is, be meshed by spline tooth between described jack shaft 3 and a left side or the right clutch, the jack shaft excircle be provided with spline tooth 4 ', left or right clutch exterior edge face is provided with spline tooth 4, spline tooth 4 ' and the spline tooth 4 coupling engagement of pegging graft mutually.
Above-mentioned open type engagement coupling, described spline tooth 4 ' cross section be rectangle, it is trapezoidal that the cross section of described spline tooth 4 should be mutually, spline tooth 4,4 ' quantity be respectively 4～8.
The utility model adopts the design of open type spline tooth, outside former inside and outside gear in being hidden in is exposed to, and the corresponding profile of tooth cross section that increased, the essentially no slide relative of spline tooth that coupling is pegged graft, so work that also can normal reliable under unlubricated condition, and the factor amount is few, sectional dimension has very high structural strength greatly, thereby improved greatly the reliability and the working life of coupling work, have that high temperature resistance, anti-water dash, the bearing capacity height, observe advantages such as maintenance is convenient, suit in abominable working environment, using.

Fig. 3 is the end view of the jack shaft 3 among Fig. 1.
Embodiment
Consult accompanying drawing, 1 is left clutch, the 2nd among the figure, right clutch, the 3rd, jack shaft, right clutch 2 and jack shaft 3 are meshed, spline tooth 4 is located on the end face of right clutch 3, spline tooth 4 ' be located on the excircle of jack shaft 3, spline tooth 4 among Fig. 3 ' shape of cross section be rectangle, the cross section of spline tooth 4 should be trapezoidal mutually among Fig. 2, the two coupling is pegged graft and is meshed, and the quantity of the two is respectively 6.
