Description
Technical field
The present invention relates to a kind of power equipment, especially a kind of power direction machine.
Background technology
In today of society's rapid development, power direction machine equipment is widely used in motor turning, compared to rack-and-pinion
Formula steering gear, power direction machine, so with higher transmission efficiency, it is light to manipulate comparison due to more relying on rolling friction
Just comfortable, the abrasion of mechanical part is smaller, and service life is relatively long, and in the past, that does not have the age of power steering, electric power
Steering wheel occupies dominant position.
Invention content
The purpose of the present invention is to provide a kind of power direction machine, to solve the problems mentioned in the above background technology.
The purpose of the present invention is be achieved by following technical proposals：A kind of power direction machine, including driving steering shaft
Circle, sector gear, steering shaft, ball nut's frame, ball-and-nut steering system, worm screw, roller, pedestal；The sector gear one
End installation driving turns to blowout patche and sector gear is installed on ball nut's frame surface；Ball nut's top of the trellis installs steering shaft
And steering shaft is through inside ball nut's frame；Installation ball-and-nut steering system and circulating ball type inside ball nut's frame
Steering side is installed by worm screw；Installation roller inside ball nut's frame；The worm screw bottom pedestal is set and pedestal with
Worm screw one end closely connects.
Further, it is a kind of loop configuration that the driving, which turns to blowout patche,.
Further, connection is engaged in described sector gear one end with ball nut's frame.
Further, the worm screw installs roller through ball nut's frame inside and worm screw inside.
Further, the multiple roller is arranged side by side inside ball nut's frame.
Compared with prior art, the beneficial effects of the invention are as follows novel a kind of power direction machine, pass through the connection of worm screw
Passing power, worm screw inside installation roller, can effectively realize worm screw smooth rotation, driving, which turns to blowout patche, can limit machine
The vibration frequency of itself ensures equipment safety operation, which is made of new material, and service life is long, makes suitable for promoting
With.
Description of the drawings
Fig. 1 is positive effect figure of the present invention；
In figure：1st, driving turns to blowout patche；2nd, sector gear；3rd, steering shaft；4th, ball nut's frame；5th, ball-and-nut steering system
System；6th, worm screw；7th, roller；8th, pedestal.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments, is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the invention discloses a kind of power direction machine, turn to blowout patche 1 including driving, sector gear 2, turn to
Axis 3, ball nut's frame 4, ball-and-nut steering system 5, worm screw 6, roller 7, pedestal 8；2 one end of sector gear installation driving
It turns to blowout patche 1 and sector gear 2 is installed on 4 surface of ball nut's frame；Steering shaft 3 is installed and is turned in 4 top of ball nut's frame
To axis 3 through inside ball nut's frame 4；The 4 inside installation ball-and-nut steering system 5 of ball nut's frame and circulating ball type
5 side of steering is installed by worm screw 6；The 4 inside installation roller 7 of ball nut's frame；6 bottom of worm screw set pedestal 8 and
Pedestal 8 is closely connect with 6 one end of worm screw；It is a kind of loop configuration that the driving, which turns to blowout patche 1,；Described 2 one end of sector gear with
The engagement connection of ball nut's frame 4；The worm screw 6 installs roller 7 through 4 inside of ball nut's frame and 6 inside of worm screw；It is described more
A roller 7 is arranged side by side inside ball nut's frame 4.
In the use of the present invention, when steering screw rotates, power is transmitted to by steering nut by steel ball, nut moves in an axial direction
It is dynamic.Meanwhile under the frictional couple effect between screw rod and nut and steel ball, all steel balls just roll in helix channel,
It is formed " ball stream ".When steering gear works, two row steel balls only recycle in respective closed flow, do not fall out, compared to tooth
Rack-and-pinion steering-gear, power direction machine is due to more relying on rolling friction, so with higher transmission efficiency, manipulation is got up
Lighter comfortable, the abrasion of mechanical part is smaller, and service life is relatively long.
It is obvious to a person skilled in the art that the present invention is not limited to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Profit requirement rather than above description limit, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims
Variation is included within the present invention.Any reference numeral in claim should not be considered as to the involved claim of limitation.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in each embodiment can also be properly combined, forms those skilled in the art
The other embodiment being appreciated that.
