The specific embodiment
Core of the present utility model provides the assembling device of a kind of reductor and working shaft, the time suffers damage to avoid the assembling of reductor and working shaft.
In order to make those skilled in the art understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The reductor that the utility model provides and the assembling device of working shaft, reductor is shaft assembled speed reducer, comprises hoisting device, also comprises leading screw 6 and reductor thrust unit 1, and wherein, reductor thrust unit 1 has screwed hole, and screwed hole and leading screw 6 are used.
Please refer to Fig. 1, the sectional structure schematic diagram of the first specific embodiment of the reductor that Fig. 1 provides for the utility model embodiment and the assembling device of working shaft.During use, with hoisting device reductor is sling first, with leading screw 6 and working shaft 7 corresponding settings, then leading screw 6 passes from the axis hole 5 of reductor, be rotatably provided in the reductor thrust unit 1 on the leading screw 6, because reductor thrust unit 1 has the screwed hole that is used with leading screw 6, the reductor thrust unit 1 of rotation can promote reductor and move to the direction of working shaft 7 slowly, to the last reductor and working shaft 7 assemblings are complete, whole assembling process is steadily slow, there is not fierce collision cohesive process between reductor and the working shaft 7, suffer damage when having avoided reductor and working shaft 7 assembling, the shaft hole matching that has guaranteed simultaneously reductor and working shaft 7 is accurate, has guaranteed assembly quality.
Please refer to Fig. 2, the sectional structure schematic diagram of the second specific embodiment of the reductor that Fig. 2 provides for the utility model embodiment and the assembling device of working shaft.In the second specific embodiment, the assembling device of above-mentioned reductor and working shaft 7 also comprises platen 3, platen 3 is used for being pressed into reductor on working shaft 7, platen 3 movably is arranged on the leading screw 6, reductor thrust unit 1 is specially nut, nut is positioned at the side away from the platen 3 of working shaft 7, also comprises the nut whirligig.
In use, by nut whirligig rotating nut, nut promotes platen 3 in leading screw 6 motions, reductor is moved to the direction of working shaft 7 slowly, to the last reductor and working shaft 7 assemblings are complete, because the diameter of the axis hole 5 of reductor is larger, reductor thrust unit 1 will guarantee the contact area enough with reductor, so that promoting smoothly reductor moves, need special the making, and stamp screwed hole in the above, cost of manufacture is increased, simultaneously because reductor thrust unit 1 diameter is excessive, bad rotation, therefore use nut, directly purchase gets final product, and cost is lower, and nut is easy to rotation simultaneously, the nut whirligig is specially six Square handles, the diameter of nut six Square handles is enclosed within on the nut, rotates six Square handles and get final product, owing to can not guarantee the contact area enough with reductor, therefore, increase a platen 3, promote reductor and move, it is simple many that the making of platen 3 is wanted, as long as a diameter enough large sheet material make a call to a through hole, to save cost compared with beating screwed hole.
Simultaneously, be provided with pad 2 between nut and the platen 3, alleviate the frictional dissipation between nut and the platen 3, prolong both service life.
In addition, platen 3 also is provided with bearing 4, bearing 4 is between platen 3 and screw mandrel 6, because when nut moves at promotion platen 3, also can drive platen 3 rotations, platen 3 can produce certain force of sliding friction to nut, hinder the normal rotation of nut, and after bearing 4 was set, the rotation meeting of platen 3 was easy, had reduced the force of sliding friction to nut.
Concrete, leading screw 6 is fixed on the working shaft 7, certainly, also leading screw 6 can be fixed on the specific fixture, during use, leading screw 6 alignment work axles 7 are got final product, but can increase cost so undoubtedly, directly leading screw 6 is fixed on the working shaft 7, can weld at an end of leading screw 6 sheet material, stamp through hole, stamp screwed hole at working shaft 7 simultaneously, then by bolt leading screw 6 and working shaft 7 are fixed together.
Concrete, the end that leading screw 6 is fixedly connected with working shaft 7 is provided with flat board, has through hole on the flat board, the end that working shaft 7 is fixedly connected with leading screw 6 is provided with screwed hole, leading screw 6 is bolted to connection with working shaft 7, after the assembly work of finishing reductor and working shaft 7, leading screw 6 can be disassembled, retightening on working shaft 7 when using next time, can not disturb the work of working shaft 7 self.
Concrete, leading screw 6 and working shaft 7 welding after leading screw 6 is finished the assembly work of reductor and working shaft 7 like this, can be fixed on the working shaft 7 always, and do not need again install very convenience when using next time.
Concrete, leading screw 6 and working shaft 7 concentric settings are equivalent to the axis hole 5 concentric settings of leading screw 6 and reductor, and reductor thrust unit 1 is when rotary work, and the thrust that acts on the reductor is more even, and the moving stability of self is relatively good.
Concrete, the axle center of the screwed hole on the reductor thrust unit 1 and reductor thrust unit 1 center superposition, reductor thrust unit 1 are the central rotations around self when rotary work all the time, can obtain better stability.
More than the assembling device of reductor provided by the utility model and working shaft is described in detail.
Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
