Description
Background technology
The present invention relates to a kind of method for being used to match the rotating speed of transmission-drive device.To be passed in addition, the present invention relates to one kind
Dynamic-drive device, is particularly suited for being used in the present inventive method.In this transmission-drive device especially automobile
The part of comfortable driver, such as seat regulation driver, window lifting driver or similar device.Here, motor
Drive shaft pass through drive screw drives drive.The drive either directly otherwise by other gears via output shaft with
There are element to be regulated such as glass for vehicle window or seat coupling.Due on having element to be regulated and having regulation to be applied
The power customer requirement different with governing speed, different requirements may be produced in terms of the gearratio of transmission-drive device.It is actual
On, therefore drive screw is accurately consistent with drive for every kind of application target.Thus require, not only generally make all the time
The drive being made of plastics for spray to cast part, and drive screw also will ad hoc construct and be provided with special geometric form in other words
Shape.
The content of the invention
In the understanding of above-mentioned prior art, task of the invention is so proposed for matching transmission-drive device
The method of rotating speed, so as to realize different rotating speeds gearratio in other words, and thus without increase particularly for manufacturing not simultaneous interpretation
The required investments of driving wheel are spent.By the present invention, propose a kind of method for being used to match the rotating speed of transmission-drive device, have by
The drive screw of drive motor, its teeth portion engage with the pairing teeth portion on drive, wherein using identical drive
In the case of the different rotating speeds of drive are realized by using the drive screw with different line numbers, wherein the institute according to helical
The number used, n times of helical pitch when the helical pitch of the helical in drive screw is the drive screw of single line, wherein the drive
Tooth inclination angle be located at drive the tooth for different driving screw rod corresponding optimum inclination angle between.This means for
The different driving rotating speed of realization transmission-drive device and different size of driving torque is thus also realized, such as passed through
The drive screw of two-wire replaces the drive screw of single line, thus by the driving rotating speed of drive to dividing and turning over driving torque
Times.But according to the geometrical construction of drive screw and drive, the application is not restricted to single line and two-wire drive screw
On, driving rotating speed can be realized in principle on the contrary（Drive screw on single line）Size be 1/n different indexing, wherein
N means the number of helical in drive screw.
The combination that all features by least disclosed in specification and/or accompanying drawing are formed is within the scope of the present invention.
It is particularly preferred that it is used as drive screw using single line and two-wire drive screw.Because in this biography
Part in the stock size of dynamic-drive device as comfortable driver in automobile is also realized all the time in the drive screw of two-wire
Engagement of at least one helical in the teeth portion of drive, and especially described drive need not have undesirable major diameter.
It is preferably suitable for being distinguished by using transmission-drive device in the present inventive method, the driving spiral shell
Bar be made of metal and drive at least in the range of the pairing teeth portion of the teeth portion for drive screw by plastics preferably by POM
（Polyformaldehyde）It is made.By realizing flexibility of the drive to different drive screws in other words by constructed in plastic material drive
With property, and thus without the abrasion increased friction in other words for causing increase.
In order to realize that the two of drive screw helicals persistently lean against the pairing teeth portion of drive in the drive screw of two-wire
On, preferably propose to be arranged to make itself and drive simultaneously at least two subregions of the helical of the drive screw of two-wire
Teeth portion engages.
In order that the load for obtaining the pairing teeth portion of drive minimizes makes its reduction in other words, particularly preferably carry in addition
Go out, the inclination angle of the tooth of the pairing teeth portion of the drive be located at the corresponding optimum of the tooth of different driving screw rod inclination angle it
Between.
Brief description of the drawings
Further advantage, feature and the details of the present invention obtains from following description of preferred embodiments and with reference to the accompanying drawings
.
Accompanying drawing is shown：
Fig. 1 be by the present invention transmission-drive device exploded view,
Fig. 2 is the enlarged drawing in teeth portion region between drive screw and drive in transmission-drive device by Fig. 1, and
Fig. 3 is the view that Fig. 2 is corresponded in the case of using the drive screw for the two-wire for being used to lower driving rotating speed.
Embodiment
Figure 1 illustrates transmission-drive device 10, as it is especially used as the part of comfortable driver in automobile,
Such as but it is used as window lifting driver, seat regulation driver or similar device without limitation.
Transmission-the drive device 10 includes motor 11, and the motor has the shelly of armature unit 12 and two and half
Permanent magnet 13.The armature unit 12 and permanent magnet 13 are contained in the pole shell 14 of peviform, and the pole shell is formed from steel and structure
Cause deep-draw part.The motor 11 is applied in the drive screw 25 being made of metal, and the drive screw is transmission device 17
Part.The transmission device 17 is used for the rotating speed that the motor 11 is reduced while 11 moment of torsion of motor is increased, wherein
Driving torque is delivered in drive shaft 18 by transmission device 17.
The transmission device 17 is contained in the housing 20 of two-piece type, and the housing is with part 21 below being made of plastics
Part 22 above casting are configured to by aluminium.The lower part 21 and upper part 22 pass through integrally formed part 21 below
On 23 mutual shape sealed of card nose connect.The housing 20 being thusly-formed on the mounting flange 24 of upper part 22 with pole shell
14 connections.Here, pole shell 14 is rolled with its corresponding wall section towards mounting flange 24, so as to be formed between pole shell 14 and housing 20
The connection of shape sealed.
In the embodiment shown in fig. 1, the driving element of the form of drive screw 25 is integratedly configured to one of armature shaft
Point.The drive screw 25 for being configured to independent component can also be used within the scope of the invention, and it is with driving element with suitable
Methods are attached, for example, by pyrocondensation to driving element, by bonding or by the connection of shape sealed for example
Teeth portion.
As especially known from Fig. 2, helical 29 has helical pitch s to the teeth portion of the drive screw 25 of single line in other words.Here, drive
The teeth portion of dynamic screw rod 25 engages with the pairing teeth portion of the transmission device 17 with drive 26.The pairing teeth portion of the drive 26 is
This has helical teeth portion in a conventional manner.The drive 26 is made of plastics, preferably by POM（Polyformaldehyde）It is made, and constructs
Into spray to cast part.Realized in transmission-drive device 10 of the drive screw 25 with the single line with helical pitch s shown in Fig. 1 and 2
n1Rotating speed.
Itd is proposed by the present invention, drive screw 25 is replaced according to Fig. 3（As shown in Figure 2）Drive screw can alternatively be used
25a, the drive screw are configured with the drive screw 25a of the two-wire of helical 31,32 in the illustrated embodiment.It is important herein
, the helical pitch S of each helical in drive screw 25a two helicals 31,32 is（Single line）The helical of drive screw 25
Twice of 29 helical pitch s.Thus, motor 11 in other words drive screw 25,25a rotating speed it is identical when, to dividing rotating speed, also
It is the rotating speed n for saying drive 262, compared to the rotating speed n of the drive 26 when using drive screw 251For half.Two driving spiral shells
Other sizes of bar 25,25a, especially its diameter, pitch, the width etc. of helical 29,31,32 are at least substantially configured to identical
