Description

The drive unit that is used for the slide that can move controllably
Technical field
The present invention relates to a kind of drive unit that is used for the slide that can move controllably with respect to lathe base of lathe by claims 1 as described in the preamble.
Background technology
The driving mechanism of generic is for example produced on the lathe with other at the machine tool with axle long linear guide and that controllably move or slide and is used.
Linear axes drives by trapezoidal, sphere or roll forming screw drive mechanism at present usually, utilizes described linear axes can realize long and the axle of rigidity mechanically.But because often do not have operational hollow shaft motor, so main shaft or mainshaft nut must connect by odontoid belt with electric servomotor.For the reason of power match, need the transmission mechanism of preposition connection generally speaking.
The shortcoming of these solutions is, these systems are owing to need a large amount of parts (main shaft, mainshaft nut, odontoid belt, transmission mechanism), and are both complicated on the structure, purchases and very expensive.In addition, the high rigidity of main shaft is ineffective owing to the odontoid belt of the relative flexibility of being made up of elastomeric material.The inside of transmission mechanism can produce in addition reverses the gap, thus axle possible accuracy location no longer.
For making cost minimization, be known in the linear axes upper saddle in addition and directly connect with CD-ROM drive motor or transmission mechanism, thereby can cancel axis system by odontoid belt.But the cost-effective advantage that reaches thus is associated with following shortcoming, and the linear axes of Shi Xianing mechanically is not unusual rigidity in this manner, can not accurately locate.
In other solutions, use the linear DC motor.In this case, primary components (coil system) is connected with the bed piece bolt with slide and secondary parts (magnet).Therefore driving force directly produces on slide, thereby can cancel the intensive transmitting element of cost of any kind.This drive system also can mechanically be implemented under the situation that the adjusting parameter is optimized very rigidly.The shortcoming of these drive system aspects is, track must be installed on the whole length of mobile route, and this is associated with very high cost.In addition, produce very high magnetic attraction between primary components and the secondary parts, the Ci attraction is a kind of additional load to linear guide.
US 4.750.970 has introduced a kind of driver with rack and pinion combination, and its middle rack is arranged on the bed piece and pinion is arranged on the slide together with transmission mechanism and CD-ROM drive motor.Therefore pinion and tooth bar engagement also drive the slide of linear guide.Based on for the gap may appear reversing in the necessary transmission mechanism of power match, this makes that accurately the location is impossible.
DE 101 60 014 C2 disclose a kind of drive unit that is used for the slide that controllably moves of machine tool, and the servo motor that its replacement has transmission mechanism uses torque motor.Torque motor is multipole, synchronous, the strong electro-motor of torque, the direct driving pinion of transmission mechanism that connects in the middle of they can not have.Pinion and motor drive shaft are whole to be constituted.Motor is fixedlyed connected with the U-shaped bearing body of restriction circumferential chambers.Though the U-shaped cross-section by bearing body can weight reduction, this rigidity to rotor has adverse effect.Because between rotor and stator, produce magnetic attracting force,, rotor produces vibration like that so can being similar to tuning fork.This shortcoming can be avoided by additional ring flange.But any additional parts are associated with higher cost.In addition, the U-shaped make with great penetraction depth of bearing body is difficult to by the turning processing and manufacturing.Itself brings shortcoming equally the whole implementation of pinion and motor drive shaft.Because pinion should be made by hardened steel for wear reason, but axle do not need to be quenched, so this structure is unnecessarily expensive.Shortcoming in addition is, rotor is clamped on the axle like this by clamp assembly, and making rotor is not directly to center on axle, but centers by clamp assembly basically.Under the situation that the bolt on the clamp assembly is not evenly tightened, can cause the radially bump of rotor, this radially clashes into is so big, so that the operate as normal of motor may be influenced unfriendly or be even destroyed.This can seriously arrive following degree, and rotor is skidded on stator.
In the drive unit that DE 101 60 014 C2 introduce, the overhang bracket of motor drive shaft is on rolling bearing.In embodiment shown in Figure 3, use taper roll bearing.For making the reliable and long-term stable operation of taper roll bearing, the prestressed adjustment of correct bearing is most important.Two taper roll bearings are arranged on the opposed position of driver, and therefore CD-ROM drive motor and different machine parts are between the bearing.Form very long tolerance chain thus, this can make normal prestressing force adjustment be difficult to or may not.Be arranged on two stators between the taper roll bearing that clamps relatively and produce hear rate at normal operation period.Because the thermal expansion that causes thus in the shell can influence bearing prestressing force or make this bearing prestressing force change exceed the permission size greatly, thereby cause bearing to be scrapped in advance.Compare with for example ball bearing, taper roll bearing has higher moment of friction.This point can cause the intensification of taper roll bearing Nei Genggao and therefore cause bearing to be scrapped in advance.
Summary of the invention
Therefore purpose of the present invention is, provides a kind of drive unit that is improved that is used for controllably mobile slide from DE 101 60 014 C2, and this drive unit is characterised in that simple in structure and can realizes inexpensively.
Foundation purpose of the present invention is by being achieved according to the described drive unit of appended claim 1.
Be characterised in that according to drive unit of the present invention,, use a kind of rolling bearing and a kind of rolling bearing that constitutes floating bearing that constitutes rigid bearing for bolster.
Be characterised in that in addition the rotor of electro-motor directly passes through mechanical fixed part with axle, preferably connects by clamp assembly.Reach thus rotor on axle by bigger length cylinder center, thereby rotor can enough accurately center under the radially vibropendulous error situation of minimum.
Be that according to major advantage of drive unit of the present invention because fixing-unsteady bearing arrangement, the thermal expansion that causes by stator and shell intensification does not influence bearing prestressing force.The foundation of this point is, and is opposite with rigid bearing, the known permission of floating bearing thermal expansion in the vertical.
What have advantage in addition is, with opposite by the pre-disclosed solution of DE 101 60 014 C2, does not use the monoblock type embodiment of axle and pinion according to solution of the present invention, and is to use spool and the embodiment of two parts formula of pinion.Because the wearing and tearing of bearing with the pinion of tooth bar engagement are bigger than the wearing and tearing that bearing is subjected to, so pinion can be by the material manufacturing stronger than the material resistivity of axle.In addition, pinion can need not bigger repacking spending and be replaced.
According to a kind of embodiment with advantage, pinion is made up of hardened steel and axle is made up of not hardened steel with low cost.In this manner, can realize tangible cost savings.
In a kind of particularly preferred embodiment, rigid bearing is embodied as double angular contact ball bearing and is arranged in the zone of pinion.Can optimize the radial load that support is produced by the prestressing force and the driving force of pinion and tooth bar by the very high bearing of this enabling capabilities.
Floating roller may be embodied as deep groove ball bearing.
Opposite with taper roll bearing, need not the outside adjustment of bearing prestressing force complexity for ball bearing.The prestressed internal part that is adjusted at double angular contact ball bearing of bearing is internally solved.Owing to need not outside the adjustment, the long tolerance chain that makes normal prestressing force adjustment become difficulty also not producing in taper roll bearing.Ball bearing similarly has the moment of friction littler than taper roll bearing under the physical dimension situation usually in addition.Therefore ball bearing heats up by force and wear and tear unlike taper roll bearing under identical service condition obviously slowlyer thus, and this improves operational reliability and causes cost savings.
Fact proved have advantage especially be cross section of rotor T shape make.The rotor of this moulding is characterised in that weight is low weight.Although realized reduction weight, rotor itself still has required rigidity.Therefore do not need to be used for the optional feature of rotor stability, from and cause the reduction of manufacturing cost.
The embodiment that has advantage according to another kind, axle with the opposed end of pinion on rotary encoder is set, this rotary encoder is used to detect the change in location of slide.
In addition according to purpose, at the plug connector that deviates from the electric contact connection that is provided for electro-motor on the coverboard of pinion.As selection, contacting for example also can connect or the terminal box realization by the cable screw.
In a kind of particularly preferred embodiment, use torque motor as electro-motor.Utilize this powerful motor to connect transmission mechanism in the middle of can need not and provide for the necessary high torque (HT) of driving pinion.
Another advantage according to drive unit of the present invention is that employed version can be used as the combiner solution particularly well.By the conversion of motor length or diameter of motor, the driver solution of being introduced can be complementary with different load data according to type simple with low cost and mode.This point can be implemented under the situation that keeps mechanical interface (bolted physical dimension) and electric interfaces (plug connector).Wholely in addition also can under the situation of maintenance that may need or reconditioning work, save into this locality and play a role.
