Description
Technical field
The utility model belongs to Automotive Steering Technology field, is related to a kind of steering gear with sprocket drive spindle assembly；Especially fit
For high pulling torque load steering gear.
Background technology
Rack and pinion steering gear is converted into tooth bar the rotation torque transmitted from the diverted post of steering wheel and jackshaft
Linear motion, and then drive steering linkage to realize the steering of wheel；In order to the motion for realizing rack and pinion engagement system it is smooth, one
As gear adopt helical gear.The increase at gear inclination angle can cause the engagement of rack-and-pinion more steady, but while rack axis
The load in direction is also being increased by the load that helical gear teeth portion is delivered to Gear axis direction.Common rack and pinion steering
In device gear part structure, gear assembly is made up of gear, bearing and bearing limited location snap ring.In order to avoid being entered due to water, dust etc.
The engaging piece grease deterioration for entering rack and pinion engagement position and causing and engaging piece corrosion, using anti-dust seal gear upper end is realized
Sealing.
As increasing steering adopts electric power steering technology, the torque load of gear transmission is increasingly
Greatly, the axial load and radial load acted on gear is consequently increased.In the reliably working for realizing gear, it has to adopt
Take the bigger bearing of size；The increase of bearing outside diameter size directly results in matched housing inner diameter size, oil sealing outer diameter ruler
Very little increase；Housing is heavy, and the rigidity of oil sealing is substantially reduced, and the problems such as press-fiting crooked process oil sealing, poor sealing easily occurs；Especially
Ground, due to the increase of gear axial load, once bearing inner race fixation is abnormal with circlip press-in, may cause gear from shell
Body gear hole is deviate from, and causes rack and pinion engagement to fail, and to vehicle and personal property loss is brought.
The content of the invention
The utility model discloses a kind of steering gear with sprocket drive spindle assembly, to solve prior art in high pulling torque load
Direction converter bearing outside dimension, causes shell structure size, oil sealing size to increase；Housing is heavy, and the rigidity of oil sealing is substantially reduced,
Easily occur press-fiting that process oil sealing is crooked, poor sealing；The problems such as；There is the press-in of bearing inner race fixation circlip abnormal, lead
Cause gear from housing gear hole deviate from risk the problems such as.
A kind of steering gear with sprocket drive spindle assembly of the utility model, steering gear include gear axle assembly, tooth bar, housing,
End plug, anti-dust seal；Gear axle assembly includes gear shaft, steel ball, bearing outer ring, retainer；On gear shaft have the gear shaft shoulder,
Outer raceway；There is an interior raceway on the inwall of bearing outer ring, roller holder is arranged between rotary shaft and bearing outer ring；Steel
Ball, retainer are arranged between the outer raceway of gear shaft and the interior raceway of bearing outer ring；Resin cage is by steel ball circumference uniform distribution
Ground keeps being spaced on the interior raceway of the outer raceway of gear shaft and bearing outer ring；Gear axle assembly is arranged in steering gear housing body；
The bearing outer ring of gear axle assembly and steering gear housing interference fit；End plug is connected with steering gear housing screw-threaded coupling, with bearing
The spacing contact in outer ring；Anti-dust seal is arranged on end plug top, coordinates with gear axle assembly, housing seal.
Good effect of the present utility model is：In the case where identical steering output loads are provided, bearing is in footpath
Structure to direction is more compact, and cost is greatly improved；Oil sealing sealing reliability；Directly using the gear shaft shoulder as bearing steel
The support member of ball, gear shaft axial positioning structure is succinct, connection is reliable；Can thoroughly reduce in the past using collar or back-up ring
When airframe bearing axis is spacing process and assemble it is bad cause gear deviate from risk.
Description of the drawings
Fig. 1 is the utility model structural representation；
In figure：1 gear axle assembly, 2 tooth bars, 3 housings, 4 end plugs, 5 anti-dust seals, 1a gear shafts, 1b steel balls, 1c bearings
Outer ring, 1d retainers, the 1e gear shaft shoulders, the outer raceways of 1f.
Specific embodiment
One embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
The utility model embodiment is as shown in figure 1, steering gear includes gear axle assembly 1, tooth bar 2, housing 3, end plug 4, anti-
Dirt oil sealing 5；Gear axle assembly 1 includes gear shaft 1a, steel ball 1b, bearing outer ring 1c, retainer 1d；There is gear on gear shaft 1a
Shaft shoulder 1e, outer raceway 1f；There is an interior raceway, roller holder 1d is arranged in rotary shaft 1a on the inwall of bearing outer ring 1c
Between bearing outer ring 1c；Steel ball 1b, resin cage 1d are arranged on the interior of the outer raceway 1f and bearing outer ring 1c of gear shaft 1a
Between raceway；Resin cage 1d keeps steel ball circumference uniform distribution to be spaced in the outer raceway 1f's of gear shaft and bearing outer ring 1c
On interior raceway；Gear axle assembly 1 is arranged in steering gear housing 3；The bearing outer ring 1c of gear axle assembly 1 and steering gear housing 3
Interference fit；End plug 4 is connected with the screw-threaded coupling of steering gear housing 3, with the spacing contacts of bearing outer ring 1c；Anti-dust seal 5 is arranged on
The top of end plug 4, coordinates with gear axle assembly 1, the sealing of housing 3；Oil sealing sealing reliability；Gear shaft axial positioning structure is succinct,
