Description
Technical field
The utility model belongs to machine tool technical field, refers in particular to the driven wheel on a kind of machine tool chief axis.
Background technology
In field of machining, labour cost, productivity effect and processing cost more and more must be paid attention at present.Double end collet chuck numerically controlled lathe special plane, except overcoming the above problems, also can solve the complete manufacturing procedure not becoming of centre numerically controlled lathe and not reach the precision of part processing.Therefore double end collet chuck numerically controlled lathe special plane application prospect is fine, but the main shaft of production double end collet chuck numerically controlled lathe special plane relies on the two-way main shaft in Taiwan at present, the two-way main shaft in Taiwan only adopts one-way hydraulic, that left and right corner contact bearing supports, interiorly with tapering displacement, block collet chuck, in use, there are a lot of disadvantages, the speed of mainshaft is at diameter below 32 millimeters, maximum speed also can only reach 2500 revs/min, diameter is more than 72 millimeters, maximum speed is 1000 revs/min of left and right, oil leakage phenomenon is a lot, main shaft uses synchronous pulley drive and cannot be arranged on main shaft middle-end, moment of torsion is little, be not suitable for roughing feed cutting, need heavy-duty motor to drive, can cause in addition sealing poor, adding man-hour, cooling fluid is all penetrated on Timing Belt, Timing Belt is easily damaged, production efficiency is on the low side, cost is higher in addition, maintenance is also inconvenient.The gear that homogenous material is made in addition, major part is that the good noise of wearability is low, but intensity is bad, and the life-span is short; Intensity is good, and the noise that wears no resistance is also large, and the especially utilization on machine tool chief axis is turned round for a long time under high-speed case, adds lubricating condition not good, and the life-span of gear just shortens more.
Summary of the invention
The purpose of this utility model is to provide that a kind of intensity is high, muting function good, antiwear property is strong, meet the driven wheel on the machine tool chief axis of run up demand and long service life.
The purpose of this utility model is achieved in that the driven wheel on machine tool chief axis, comprise main shaft, wherein, on described main shaft, be provided with gear, described gear comprises inner ring and outer ring, described inner ring is fixedly connected with described main shaft, described inner ring adopts metal material to make, and outer nose circle is provided with groove, described outer ring adopts plastic material to make, and interior nose circle is provided with the projection fastening with described groove, outside described outer ring, nose circle is provided with the gear teeth, rigidity and tenderness combines, good toughness, shock-resistant, intensity is high, resistance to wear, noise is little, and outer ring can produce separately and be installed on inner ring, cost of manufacture is low, assemble simple and convenient, and long service life.
According to the driven wheel on the machine tool chief axis of the above, wherein, the outer nose circle of described inner ring is provided with anti-slop serrations, inner ring is combined more firm with outer ring, and in the course of the work, and inner ring and outer ring can relative slidings, work more stable.
According to the driven wheel on the machine tool chief axis of the above, wherein, described gear is positioned at the middle part of described main shaft, makes the acting on main shaft of power equilibrium of gear output, guarantees that main shaft has reliable and stable circumferential rotating speed.
According to the driven wheel on the machine tool chief axis of the above, wherein, described gear is spur gear or helical gear.
According to the driven wheel on the machine tool chief axis of the above, wherein, the plastic material that described outer ring adopts is specially nylon, and intensity is high, muting function good, antiwear property is strong, dimensional stability is good.
The utility model compared to existing technology outstanding and useful technique effect is: adopt nylon as the outer ring of gear, the characteristic that utilize the intensity of nylon high, antiwear property is strong, dimensional stability is good, can meet the demand of main shaft High Rotation Speed, and muting function is good, long service life, cost of manufacture is low.

Fig. 2 is the structural representation of main shaft and inner ring in Fig. 1;
In figure: 10-main shaft, 11-inner ring, 12-outer ring, 13-groove, 14-anti-slop serrations, 15-projection, the 16-gear teeth.
The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-2: the driven wheel on machine tool chief axis, comprise main shaft 10, wherein, on described main shaft 10, be provided with gear, described gear comprises inner ring 11 and outer ring 12, described inner ring 11 is fixedly connected with described main shaft 10, described inner ring 11 adopts metal material to make, and outer nose circle is provided with groove 13, described outer ring 12 adopts plastic material to make, and interior nose circle is provided with the projection 15 fastening with described groove 13, the outer nose circle in described outer ring 12 is provided with the gear teeth 16, rigidity and tenderness combines, good toughness, shock-resistant, intensity is high, resistance to wear, noise is little, outer ring 12 is integrated by cast and inner ring 11, and outer ring 12 also can produce separately and be installed on inner ring 11, cost of manufacture is low, assemble simple and convenient, and long service life, also easy maintain and replace.
Further optimize, the outer nose circle of described inner ring 11 is provided with anti-slop serrations 14, make inner ring 11 with outer ring 12 in conjunction with more firm, and in the course of the work, inner ring 11 and outer ring 12 can relative slidings, work more stable.
Further optimize, described gear is positioned at the middle part of described main shaft 10, makes the acting on main shaft 10 of power equilibrium of gear output, guarantees that main shaft 10 has reliable and stable circumferential rotating speed, improves the machining accuracy of product.
Preferably, described gear is helical gear, and engagement property is good, and stable drive, noise are little, and registration is large, has reduced the load of every pair of gear, has improved the bearing capacity of gear, and the minimum teeth number that does not produce undercut is few.
Further optimize, the plastic material that described outer ring 12 adopts is specially nylon, and intensity is high, muting function good, antiwear property is strong, dimensional stability is good.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
