Description
technical field:
The utility model belongs to machine tool field, relates to a kind of building-block machine drive mechanism
,relate in particular to the poor gear of a kind of building-block machine gap drive mechanism that disappears.
background technology:
At present, in prior art in the power part of milling head, the first-class building-block machine of boring, the size of the drive gap between mainshaft gear and shaft gear, often has influence on the robust motion of milling head, thereby have influence on the machining accuracy of workpiece, also have influence on the durability of cutter.Traditional way is generally taked helical gear structure and is improved accuracy of gear grade, reduces the drive gap between gear with this, improves the stationarity of transmission.But in real work, although equipment precision is very high, the gapped existence of federation.Need a kind of device of eliminating main shaft and shaft gear drive gap badly, eliminate milling head, the first-class building-block machine power part of boring gear drive gap in the time working to realize, improve the stationarity of transmission, improve machining accuracy and the tool life of workpiece.
utility model content:
The purpose of this utility model is to provide a kind of compact conformation, easy to use, dependable performance, can eliminate milling head, the first-class building-block machine power part of boring gear drive gap in the time of work, the poor gear of building-block machine that improves Workpiece Machining Accuracy and the tool life gap drive mechanism that disappears.
The technical solution of the utility model is: the poor gear of the building-block machine gap drive mechanism that disappears, comprises shaft gear, driving key, power transmission shaft, mainshaft gear, main shaft, clearance elimination gear, bakelite plate friction plate, hold-down ring, butterfly spring, packing ring, holding nut, holds out against screw, feather key, housing screw, resilient sleeve; Travelling gear is fixedly connected with power transmission shaft by driving key, mainshaft gear is fixedly connected with main shaft, clearance elimination gear cooperation is arranged on mainshaft gear, the relative mainshaft gear of clearance elimination gear can do circumference relative motion, clearance elimination gear engages with shaft gear together with mainshaft gear, and holding nut is fixed on mainshaft gear by screw thread.
On described mainshaft gear, be provided with feather key and hold-down ring, coordinate the rear hold-down ring of installation and mainshaft gear to do axially and relatively move; Mainshaft gear and main shaft junction are provided with housing screw and resilient sleeve.
Described holding nut is along the circumferential direction arranged one group of screw, installs one group and hold out against screw in screw, holds out against screw and holds out against hold-down ring by pad and butterfly spring, and hold-down ring holds out against clearance elimination gear.
In described clearance elimination gear both ends of the surface, be consolidated with bakelite plate friction plate.
The utility model adopts after technique scheme can reach following beneficial effect: the poor gear of this novel building-block machine gap drive mechanism that disappears
,serviceability is reliable, can effectively eliminate the drive gap of mainshaft gear and shaft gear, guarantee mainshaft gear and shaft gear tight mesh all the time in transmission process, further improved transmission stability, thereby improved machining accuracy and the tool life of workpiece.
accompanying drawing explanation:
Fig. 1 is the disappear main TV structure schematic diagram of gap drive mechanism of the poor gear of the utility model building-block machine.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 1: the poor gear of the building-block machine gap drive mechanism that disappears, comprises shaft gear 1, driving key 2, power transmission shaft 3, mainshaft gear 4, main shaft 5, clearance elimination gear 6, bakelite plate friction plate 7, hold-down ring 8, butterfly spring 9, packing ring 10, holding nut 11, holds out against screw 12, feather key 13, housing screw 14, resilient sleeve 15.Travelling gear 1 is fixedly connected with power transmission shaft 3 by driving key 2, mainshaft gear 4 is fixedly connected with main shaft 5 with resilient sleeve 15 by housing screw 14, bakelite plate friction plate 7 is fixedly connected in clearance elimination gear 6 both ends of the surface, clearance elimination gear 6 cooperations are arranged on mainshaft gear 4, the relative mainshaft gear 4 of clearance elimination gear 6 can do circumference relative motion, clearance elimination gear 6 engages with shaft gear 1 together with mainshaft gear 4, hold-down ring 8 coordinates installation by feather key 13 with mainshaft gear 4, hold-down ring 8 can do axially and relatively move with mainshaft gear 4, holding nut 11 is fixed on mainshaft gear 4 by screw thread, holding nut 11 is along the circumferential direction arranged one group of screw, in screw, install one group and hold out against screw 12, holding out against screw 12 holds out against at hold-down ring 8 by pad 10 and butterfly spring 9, hold-down ring 8 holds out against the clearance elimination gear 6 of pasting bakelite friction plate 7.
When work, shaft gear 1 engages mainshaft gear 4 and clearance elimination gear 6 simultaneously, and clearance elimination gear 6 is than more than 4 gear teeth of mainshaft gear, therefore, the every rotation one of main shaft 5 is enclosed, and clearance elimination gear 6 will rotate to main shaft 5 the circumference swing offset of a tooth of rightabout rotation with respect to mainshaft gear 4, and this relative swing offset promotes clearance elimination gear 6 by the driving cog back side of shaft gear 1 and produces, meanwhile, the driving cog front of shaft gear 1 is just promoting mainshaft gear 4 and is rotating.Because clearance elimination gear 6 is held out against screw 12 by packing ring 10, butterfly spring 9, hold-down ring 8 holds out against on mainshaft gear 4 sides, make clearance elimination gear 6 rotation relative to mainshaft gear 4, shaft gear 1 must act on contrary power to mainshaft gear 4 and clearance elimination gear 6, namely the driving cog front and back of shaft gear 1 promotes the corresponding flank of tooth of mainshaft gear 4 and clearance elimination gear 6 simultaneously, this power exists all the time in transmission process, thereby guarantee that shaft gear 1 contacts with the gapless of mainshaft gear 4 and clearance elimination gear 6, realize gapless driving, improve transmission stability, improve machining accuracy and tool life.
