Detailed description of the invention
Core of the present invention is to provide the assembling device of a kind of reductor and working shaft, to avoid suffering damage when reductor and working shaft assembling; Another core of the present invention is to provide the assembly method of a kind of reductor and working shaft.
In order to make those skilled in the art understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The assembling device of reductor provided by the invention and 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, screwed hole and leading screw 6 with the use of.
Please refer to Fig. 1, the sectional structure schematic diagram of the first detailed description of the invention of the assembling device of the reductor that Fig. 1 provides for the embodiment of the present invention and working shaft.During use, first with hoisting device, reductor is sling, arrange corresponding with working shaft 7 for leading screw 6, then leading screw 6 passes from the axis hole 5 of reductor, be rotatably provided in the reductor thrust unit 1 on leading screw 6, due to reductor thrust unit 1 have with leading screw 6 with the use of screwed hole, the reductor thrust unit 1 rotated can promote reductor and move to the direction of working shaft 7 slowly, to the last reductor and working shaft 7 assemble complete, whole assembling process is steadily slow, fierce collision cohesive process is not had between reductor and working shaft 7, avoid when reductor and working shaft 7 assemble and suffer damage, ensure that the shaft hole matching of reductor and working shaft 7 is accurate simultaneously, ensure that assembly quality.
Please refer to Fig. 2, the sectional structure schematic diagram of the second detailed description of the invention of the assembling device of the reductor that Fig. 2 provides for the embodiment of the present invention and working shaft.In the second detailed description of the invention, the assembling device of above-mentioned reductor and working shaft 7 also comprises platen 3, platen 3 for being pressed into reductor on working shaft 7, platen 3 is movably arranged on leading screw 6, reductor thrust unit 1 is specially nut, nut is positioned at the side of the platen 3 away from working shaft 7, also comprises nut whirligig.
In use, by nut whirligig rotating nut, nut promotes platen 3 and moves on leading screw 6, reductor is moved to the direction of working shaft 7 slowly, to the last reductor and working shaft 7 assemble complete, because the diameter of the axis hole 5 of reductor is larger, reductor thrust unit 1 will ensure the contact area enough with reductor, to promote reductor smoothly to move, need special making, and stamp screwed hole above, cost of manufacture can be made to increase, simultaneously because reductor thrust unit 1 diameter is excessive, bad rotation, therefore nut is used, directly to buy, cost is lower, nut is easy to rotate simultaneously, nut whirligig is specially six Square handles, six Square handles are enclosed within nut, rotate six Square handles, because the diameter of nut can not ensure the contact area enough with reductor, therefore, increase a platen 3, promotion reductor moves, the making of platen 3 wants simple many, as long as make a call to a through hole on the sheet material that diameter is enough large, cost will be saved compared with beating screwed hole.
Meanwhile, between nut and platen 3, be provided with pad 2, alleviate the frictional dissipation between nut and platen 3, the service life of both prolongations.
In addition, platen 3 is also provided with bearing 4, bearing 4 is between platen 3 and leading screw 6, because nut, when promoting platen 3 and moving, also can drive platen 3 to rotate, platen 3 can produce certain force of sliding friction to nut, hinder the normal rotation of nut, and after arranging bearing 4, the rotation of platen 3 easily, can reduce the force of sliding friction to nut.
Bearing 4 is positioned at the side away from reductor thrust unit 1 on platen 3, and to avoid bearing 4 directly to contact with nut, nut is when promoting platen 3 and moving, and too much thrust drops on bearing 4, occurs the phenomenon that bearing 4 is separated with platen 3, and impact normally works.
Concrete, leading screw 6 is fixed on working shaft 7, certainly, also can be fixed in specific fixture by leading screw 6, during use, by leading screw 6 alignment work axle 7, but can cost be increased undoubtedly like this, directly leading screw 6 is fixed on working shaft 7, can one end of leading screw 6 welding on sheet material, stamp through hole, on working shaft 7, stamp screwed hole simultaneously, then by bolt, leading screw 6 and working shaft 7 are fixed together.
Concrete, leading screw 6 and working shaft 7 concentric are arranged, be equivalent to leading screw 6 arrange with axis hole 5 concentric of reductor, reductor thrust unit 1 is when rotary work, and the thrust ratio acted on reductor is comparatively even, and the moving stability of self is relatively good, if the axle center of the screwed hole on reductor thrust unit 1 overlaps with reductor thrust unit 1 center of gravity, reductor thrust unit 1, when rotary work, is the center of gravity rotation around self all the time, can obtains better stability.
The present invention also provides the assembly method of a kind of reductor and working shaft, and reductor is shaft assembled speed reducer, comprising:
Step 1) leading screw is set, the axis hole 5 of reductor, just to working shaft 7, is enclosed within leading screw by leading screw 6;
Step 2) the reductor thrust unit 1 that has screwed hole is set on leading screw 6, screwed hole and leading screw 6 with the use of.
Step 3) rotate reductor thrust unit 1, promote reductor, make working shaft 7 enter the axis hole 5 of reductor.
Whole assembling process is steadily slow, does not have fierce collision cohesive process between reductor and working shaft 7, avoids when reductor and working shaft 7 assemble and suffers damage, ensure that the shaft hole matching precision of reductor and working shaft 7 simultaneously, ensure that assembly quality.
Concrete, step 2) also comprise step 21) platen 3 is set on leading screw 6, reductor thrust unit 1 is nut,
Step 3) be specially with six Square handle rotating nuts, nut promotes platen 3 along leading screw 6, and platen 3 extrudes reductor, makes working shaft 7 enter the axis hole 5 of reductor.
Because the diameter of the axis hole 5 of reductor is larger, reductor thrust unit 1 will ensure the contact area enough with reductor, moves to promote reductor smoothly, cause reductor thrust unit 1 diameter excessive, bad rotation, therefore uses nut, and nut is easy to rotate, six Square handles are enclosed within nut, rotate six Square handles, because the diameter of nut can not ensure the contact area enough with reductor, therefore, increase a platen 3, promote reductor and move.
Concrete, step 1) middle leading screw 6 is just being specially leading screw 6 to working shaft 7 and working shaft 7 concentric is arranged, when leading screw 6 and working shaft 7 concentric, be equivalent to leading screw 6 arrange with axis hole 5 concentric of reductor, reductor thrust unit 1 is when rotary work, the thrust ratio acted on reductor is comparatively even, and the moving stability of self is relatively good, and reductor thrust unit 1 promotes when reductor moves more steady on leading screw 6.
Above the assembling device of reductor provided by the present invention and working shaft and assembly method are described in detail.
Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
