Driving gear assembly comprises drive sprocket axle 5, capstan 3 and driving gear 1, and capstan 3 uses for being wound around waterproof insulation winding 13.The bottom of drive sprocket axle 5 is fixedly mounted on guide rail mechanism 7, and capstan 3 is fixedly mounted on driving gear 1 top and is arranged on drive sprocket axle 5 tops by bearing A6, and handle 12 is installed on capstan 3.Handle 12 can be arranged on the position, inclined to one side outer of capstan 3, and capstan 3 is fixed as one with driving gear 1, by driving handle 12, drives capstan 3 to rotate, and also drives driving gear 1 to rotate.Compress guide wheel assembly and comprise compression guide wheel 4, driven gear 2 and follower shaft 10, compress guide wheel 4 for coordinating the cooperation guide wheel of capstan 3, capstan 3 is corresponding with the installation site that compresses guide wheel 4, by cooperatively interacting of capstan 3 and compression guide wheel 4, has been guaranteed waterproof insulation winding 13 at capstan 3 and has been compressed the transmission on guide wheel 4.
As shown in Figure 9 and Figure 10, in order there to be the wet type electric motor that facilitates better different size, the excircle of capstan 3 is provided with main line 23, the excircle that compresses guide wheel 4 is provided with from groove 24, groove can be semicircular arc, its size can be taken into account all specifications design of wet type electric motor product waterproof insulation winding wire used by considering, and within the displacement scope of gear.Waterproof insulation winding 13 is at main line 23 with between groove 24, under the drive of capstan 3, move, can also all be stained with at main line 23 with from groove 24 thermal shrinkable sleeve, wear-resistant, corrosion-resistant, shock proof characteristic that thermal shrinkable sleeve has, avoids the direct contact of wire insulation and plain conductor and damages.When waterproof insulation winding 13 is pressed onto by the groove of capstan 3 and compression guide wheel 4, gently draw waterproof insulation winding 13, utilize the frictional force between waterproof insulation winding 13 and capstan 3 and the groove of compression guide wheel 4, the compression and the positioning action that are aided with three compression guide wheels 4, making waterproof insulation winding 13 can be driving gear 1 and driven gear 2 transmissions and move along with capstan 3.
Compressing guide wheel 4 is fixedly mounted on driven gear 2 tops and is arranged on follower shaft 10 tops by bearing B11, compressing guide wheel 4 and driven gear 2 is fixed as one, driving gear 1 is corresponding with the installation site of driven gear 2, when driving gear 1 advances while putting in place at guide rail mechanism 7, together with driving gear 1 is intermeshing with driven gear 2, by driving gear 1 and cooperatively interacting of driven gear 2, has guaranteed at capstan 3 and compressed the rotation that drives driving gear 1 and driven gear 2 when guide wheel 4 rotates.If driving gear 1 and driven gear 2 are not installed in capstan 3 and the bottom that compresses guide wheel 4, for the waterproof insulation winding 13 that reaches hundreds of rice in use, cannot promote capstan 3, the manpower of required use is also larger than pure manual operations.Install respectively after driving gear 1 and driven gear 2 bottom of capstan 3 and compression guide wheel 4, when driving handle 12 drives capstan 3 to rotate, compressing guide wheel 4 coordinates capstan 3 to rotate, and driving gear 1 under capstan 3 is also driven, by driving gear 1 and the engagement of driven gear 2, carry out transferring power, reduced greatly the active force of required use.
The quantity that compresses guide wheel assembly can be 3, and 3 compress the outside that guide wheel assembly is distributed in driving gear assembly, can three directions except handwheel 14 be installed by cooperation at driving gear assembly.By 3 compression guide wheels 4, coordinate with capstan 3 like this, can better guarantee the transmission of 3 pairs of waterproof insulation windings 13 of capstan and stablize; By coordinating of 3 driven gears 2 and driving gear 1, can more reduce the active force of driving handle 12, promote capstan 3 lighter.In order to adjust more easily parallel at stator support 19 two ends of threading mechanism A17 and threading mechanism B18, can also comprise adjustable feet 16, the quantity of adjustable feet 16 is 4, adjustable feet 16 is arranged on respectively the below of support 15.By adjusting adjustable feet 16, can make within the specific limits easily threading mechanism A17 or threading mechanism B18 keep horizontal direction parallel.
The modulus of driving gear 1 is that 8mm, pressure angle are that 20 degree, the number of teeth are that 55, reference diameter are that 440mm, tip diameter are that 456mm, root diameter are that 420mm, height of teeth top are that 8mm, height of teeth root are that 10mm, whole depth are 18mm.The modulus of described driven gear 2 is that 8mm, pressure angle are that 20 degree, the number of teeth are that 12, reference diameter are that 96mm, tip diameter are that 112mm, root diameter are that 76mm, height of teeth top are that 8mm, height of teeth root are that 10mm, whole depth are 18mm.Driving gear 1 is that 268mm, gear ratio are 4.583 with the centre-to-centre spacing of driven gear 2.Driving gear 1 and driven gear 2 adopt large modulus straight gear, can allow gear under displacement condition in a big way, mesh operation, to make capstan 3 and the compression guide wheel 4 of direct connection with it can clamp and drive the winding wire of different wire diameters to complete threading work, widened the working range of this covering device.Driving gear 1 and driven gear 2 modulus m=8, whole depth reaches 18mm, is engaged with a larger displacement, when winding wire around small diameter (the large external diameter that refers to having insulation sheath), meshes morely, and displacement is smaller; When around larger-diameter wire gauge, engagement is few, and displacement is larger, does not in either case affect the effect of transmission.In manual transmission operation, displacement transmission is negligible on the impact of gear.Driving handle 12 drives winding wire to rotate, and gearratio i=4.583 winding mode compares to manual direct cable, and its labour-saving effect is apparent.And driving gear 1 and driven gear 2 can Bidirectional drivings, not only can be for coiling, can also be for the bracing wire of taking out stitches.
When reality is used, as shown in Figure 6, at one, hold and have in the Special seal in clear water pond operating room, stator core in motor casing 22 20 use stator supports 19 are propped, at stator support 19 two ends, place threading mechanism A17 and threading mechanism B18, adjust the height of adjustable feet 16, make to treat that the closed slot 21 of stator core 20 is highly basically identical with threading mechanism A17 and threading mechanism B18.Before threading, first rotate the handwheel 14 on threading mechanism B18, by handwheel, 14 sliding guides mechanisms 7 retreat, and driving gear 1 and capstan 3 are pulled out, and now driving gear 1 exits engagement with driven gear 2.The distance of capstan 3 and 4 grooves of compression guide wheel widens, and can hold waterproof insulation electromagnetism winding wire 13 and pass, and now places on threading mechanism A17 and threading mechanism B18 and does not have waterproof insulation winding 13.
Operative employee's hand is carried the end of incoming cables of waterproof insulation winding 13, is passed stator core 20 corresponding closed slot silicon steel sheet 21(the first grooves), make again afterwards the end of incoming cables of waterproof insulation winding 13 pass the groove that threading mechanism B18 goes up capstan 3 and compresses 4, guide wheel.After the main line 23 of waterproof insulation winding 13 capstan 3 from threading mechanism B18 is pulled out, rotate again the handwheel 14 on threading mechanism B18, guide rail mechanism on threading mechanism B18 7 is done to forward travel, thereby drive driving gear 1 and capstan 3 on threading mechanism B18 to reset with driven gear 2 and compression guide wheel 4, driving gear 1 and driven gear 2 engagements.The end of incoming cables that hauls waterproof insulation winding 13 uses the same method and allows winding wire pass through threading mechanism A17 at stator support 19 other ends after passing from another iron core slot (the second groove) of corresponding span again.Handwheel 14 on same moving threading mechanism A17, retreats guide rail mechanism 7, and driving gear 1 and capstan 3 are pulled out, and driving gear 1 exits engagement with driven gear 2.By the end of incoming cables that hauls waterproof insulation winding 13, on capstan 3, now the waterproof insulation winding 13 on capstan 3 can rotate freely, and the end of incoming cables of waterproof insulation winding 13 is drawn on the ground after the capstan 3 through threading mechanism A17.
Now rotate respectively the handle 12 on threading mechanism A17 and threading mechanism B18 simultaneously, winding wire slowly moved, until the first diatom by winding wire across two wire casings.All draw threading mechanism A17 on one side remaining winding wire.Stop the rotating operation of handle 12, the handwheel 14 that unscrews threading mechanism B18 exits line.Now winding wire has passed in two iron core slots, the other end of winding wire by fabrication techniques of the prior art on corresponding iron core slot.Now winding wire has been the situation of tension between threading mechanism A17 and threading mechanism B18, cannot take off from threading mechanism B18, therefore at this, need to unscrew the handwheel 14 of threading mechanism B18, guide rail mechanism on threading mechanism B18 7 is retreated, to stator support 19 directions, move, the winding wire being wrapped in like this on threading mechanism B18 just can become flexible, thereby takes out from the capstan 3 of threading mechanism B18.And then the moving threading mechanism A17 of continuation dish,, to iron core root, colligation is in winding wire end to tighten up last point winding wire (winding wire taking out from the capstan 3 of threading mechanism B18).
The end of incoming cables of waterproof insulation winding 13 passed to first groove and threading mechanism B18 to repeat above-mentioned steps again thereafter, until all move line to threading mechanism B18 on one side, unclamp the guide rail mechanism 7 of threading mechanism A17, tighten up last point winding wire (winding wire taking out from the capstan 3 of threading mechanism A17) to iron core root, colligation winding wire end.So move in circles, until a waterproof insulation winding wire that reaches hundreds of meters all pierces in corresponding two wire casings of stator core 20.Last colligation is exposed at the winding wire of end, completes and squeezes into slot wedge, makees joint, the work such as shaping, so that complete the threading work of whole stator core 20.
