Description
Technical field
The utility model relates to a kind of cylinder assembly of Flying Dutchman.
Background technology
Existing Flying Dutchman comprises cylinder body and is connected to the end cap at cylinder body two ends, and end cap is provided with axle installing hole, and axle installing hole is built with the axle be connected with end cap, and axle is integral type structure.The inwall of cylinder body is provided with many annular grooves, forms ring muscle between adjacent annular groove, and the effect of annular groove is to gather condensed water, prevents condensed water from forming ring cascade, thus reduces heat transference efficiency; And annular groove need have machining equipment to process, because the build of cylinder body is comparatively large, processing and fabricating is wasted time and energy, very difficult, causes cost of manufacture to remain high.The axle of integral structure, bulky and weight is large, not only processing and fabricating difficulty, but also there is the shortcoming of assembling difficulty, in addition, during drying cylinder work, be connected with high temperature and high pressure steam in it, end cap will overcome the pressure of steam on the one hand, will overcome the axial elongated top pressure caused it because axle is heated on the other hand, thus cause the bearing capacity of end cap little, easily cause danger.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of cylinder assembly making easy and that cost is low Flying Dutchman.
For solving the problems of the technologies described above, the utility model provides a kind of cylinder assembly of following structure, comprise the cylinder body of steel, the two ends of cylinder body are connected with end cap, described end cap is provided with axle installing hole, its design feature is the soldered tabulator bars having many intervals to be periphery on described inboard wall of cylinder block, and the length direction of described tabulator bars is consistent with the axis of cylinder body.
Described tabulator bars is solid construction, and the tabulator bars heat transference efficiency of solid construction is higher.
The cylinder assembly of said structure, on inboard wall of cylinder block, the many ribs axially arranged are defined by the mode of the tabulator bars having many intervals to be periphery soldered on inboard wall of cylinder block, the water leg axially arranged is formed between adjacent rib, the condensed water entering the steam generation in cylinder body just can collect in water leg, can prevent condensed water in cylinder body rotation process from forming cascade, the transmission efficiency of heat can not be affected.Form water leg by the mode of welding tabulator bars, compared with the mode of existing machining, cost of manufacture is low, and speed is fast.
Described axle installing hole is built with the axle of hollow structure, and described axle is two body structures be made up of fore side half axle and transmission side half axle.The axle of two body structures, processing and fabricating is easily convenient.
The technical scheme improved is: described fore side half axle comprises fore side half axle body and is connected to the fore side spindle nose of fore side half axle body outer end, and fore side half axle body outer end is provided with fore side end flange for being connected with end cap, the inner is provided with end flanges in fore side; Described transmission side half axle comprises transmission side half axle body and is connected to the transmission side spindle nose of transmission side half axle body outer end, and transmission side half axle body outer end is provided with transmission side end flange for being connected with end cap, the inner is provided with end flanges in transmission side; In described transmission side, end flanges and the diameter of end flanges in fore side are all less than the diameter of axle installing hole and together with the two is bolted.
In transmission side, in end flanges and fore side, the diameter of end flanges is all less than the design of the diameter of axle installing hole, fore side half axle can be realized carry out installing and being connected with end cap from the two ends of cylinder body respectively with transmission side half axle, with bolt, end flanges in transmission side is connected with end flanges in fore side more afterwards, makes to install more easily quick.
The technical scheme of further improvement is, the chamber segment length sum that described fore side half axle and transmission side half axle are positioned at inner chamber of cylinder block is less than the axial length of inner chamber of cylinder block.
The chamber segment length sum being positioned at inner chamber of cylinder block due to fore side half axle and transmission side half axle is less than the axial length of inner chamber of cylinder block, after fore side half axle has been connected on end cap with transmission side half axle, gap can be produced between the two the inner, the bolt of end flanges in two can be fastenedly connected further, make gap shrinks, pretension is applied to two end cap, two end cap is made to occur inwardly elastic deformation to occur, like this, during drying cylinder work, the pressure that steam produces end cap and because axle is heated axially the elongated pressure on top surface that it is caused just can offset above-mentioned pretension, thus make end cap can bear higher pressure.
The technical scheme further improved is: be provided with pad between end flanges in end flanges and fore side in described transmission side.Due to the existence of pad, the bolted connecting end flanges in two to a certain extent time, pad will tightly be clamped by the inner of fore side half axle and transmission side half axle, even if fastening bolt further, also can not produce and pulling is further produced to end cap, can prevent the pretension of end cap applying excessive like this.
Described fore side half axle body and fore side spindle nose and transmission side half axle body and transmission side spindle nose are the integrative-structure by casting, its intensity of raising like this.
In sum, the utility model has the advantage of: cylinder body processing is easily quick, and cost of manufacture is low; Axle is easy to make, and assembling easily, can improve the bearing capacity of drying cylinder end cover.
