Abstract
The utility model proposes a kind of automobile using multiple lead screw, including leading screw body, it is characterised in that：The lateral surface of leading screw body is provided with multiple thread, and the side of leading screw body is provided with available for the spline being installed on automobile, wherein, multiple thread includes multiple tooth portions, and the groove portion being formed between phase adjacent teeth portion.Automobile using multiple lead screw processing tooth head is trapezoidal, and its facing roughness is 5mm, more accurate.
Description
Technical field
The utility model belongs to leading screw field, more particularly to a kind of multiple lead screw of automobile using.
Background technology
Multiple lead screw refers to there is multiple thread on leading screw, and multiple thread herein refers to coaxially there is hand of helix one
Cause but the screw thread of the different two or more ridge of pitch is referred to as multiple thread.It is in the ridge number of the different screw thread of pitch
In the case of 2, multiple thread is referred to as double thread, in the case that ridge number is 3, is referred to as three-start screw, ridge number
In the case of 4, in the case of being referred to as four head thread ... .. ridges numbers for n, it is referred to as n head threads.
And existing multiple lead screw, its surface are more coarse, especially in applied to automobile, its precision does not reach much
Automotive needs, reduce overall service life.
The content of the invention
In order to solve the above problems, the utility model provides a kind of automobile using multiple lead screw, the automobile using multiple lead screw
Tooth head is processed to be trapezoidal, and its facing roughness is 5mm, it is more accurate.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of automobile using multiple lead screw, including leading screw body, the lateral surface of leading screw body are provided with multiple thread, leading screw sheet
The side of body is provided with available for the spline being installed on automobile, wherein, multiple thread includes multiple tooth portions, and is formed at phase
Groove portion between adjacent teeth portion.
As further optimization of the present utility model, the cross section in tooth portion is trapezoidal.
As further optimization of the present utility model, the helical angle of trapezoidal thread is 27.94 °.
As further optimization of the present utility model, the spacing between phase adjacent teeth portion is 299.9mm~300.1mm.
As further optimization of the present utility model, the facing roughness in tooth portion is 5mm.
As further optimization of the present utility model, multiple thread is 5 head threads of dextrorotation.
Compared with prior art, it is the advantages of the utility model with good effect：The more captaculas of the utility model automobile using
Thick stick, it processes tooth head to be trapezoidal, and under the processing of numerically-controlled precise screw-rolling machine, can reach facing roughness is 5mm, more accurate.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model automobile using multiple lead screw；
Fig. 2 is the sectional view of facing on automobile using multiple lead screw.
Above in each figure：1st, leading screw body；11st, tooth portion；12nd, groove portion；2nd, spline.
Embodiment
Below, the utility model is specifically described by exemplary embodiment.It should be appreciated, however, that do not having
In the case of being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations
In mode.
, it is necessary to explanation, term " interior ", " outer ", " on ", " under ", "front", "rear" etc. in description of the present utility model
The orientation or position relationship of instruction are based on position relationship shown in the drawings, are for only for ease of description the utility model and simplification
Description, rather than the device or element of instruction or hint meaning must have specific orientation, with specific azimuth configuration and behaviour
Make, therefore it is not intended that to limitation of the present utility model.
As depicted in figs. 1 and 2, automobile using multiple lead screw of the present utility model, including leading screw body 1, leading screw body 1 it is outer
Side is provided with multiple thread, and the side of leading screw body 1 is provided with available for the spline 2 being installed on automobile, wherein, bull spiral shell
Line includes multiple tooth portions 11, and the groove portion 12 being formed between phase adjacent teeth portion.Multiple-threaded setting, make the effect of lead screw transmission
Rate is significantly improved.
In above-mentioned, the processing of spline 2 realizes the direct-drive with motor in automobile, and precision is higher.Will during processing
Seek impulse- free robustness on spline 2.
With continued reference to Fig. 2, as shown in Fig. 2 the cross section of tooth portion described in above-mentioned 11 is trapezoidal.The tooth pitch change of phase adjacent teeth portion
Amount ± 0.1/300mm.In addition, in the utility model, in above-mentioned, the helical angle of trapezoidal thread is 27.94 °, the facing in tooth portion 11
Roughness control is 5mm, and three-needle measuring distance is 11.49mm, a diameter of 1.75mm of three pins.
Preferably, multiple thread is 5 head threads of dextrorotation in the utility model.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change is applied to other fields, but every without departing from the content of the technical scheme of the utility model, according to this reality
Any simple modification, equivalent variations and the remodeling made with new technical spirit to above example, it is new to still fall within this practicality
The protection domain of type technical scheme.
