Abstract
The invention provides a rotary valve assembly of a steering machine and an installation method thereof. The rotary valve assembly comprises a rotary valve assembly and a pinion and a bearing which are contained in the rotary valve assembly, a shell and a rack which is contained in the shell; the pinion and the bearing in the rotary valve assembly are arranged in the shell; the pinion and the rack in the shell are engaged with each other; the invention also comprises a sealing ring which is arranged on the shaft shoulder of the root of the pinion through a sealing ring liner. When installed, a protection sleeve is first sheathed at the tooth part of the pinion; the sealing ring linear and the sealing ring are then sheathed on the shaft shoulder at the root of the pinion of the rotary valve through the protection sleeve; the protection sleeve is then taken out; finally the pinion of the rotary valve assembly and the sealing ring linear as well as the sealing ring are arranged into the shell together to implement the assembly operation. As the sealing ring is arranged on the small gear through the protection sleeve, the phenomenon of trimming between the sealing ring and the pinion is avoided, and the qualified rate of the air tightness test of steering machine is greatly improved.
Description
Technical field
The present invention relates to the valve packe and the installation method of automotive steering structure.
Background technology
The present valve packe of producing, when assembly assemble, generally the method for Cai Yonging was: first the housing seal circle is pressed in the housing, passes the seal ring inner ring by miniature gears then, with the tooth bar correct engagement, thereby make the rotary valve tram of packing into, finish fitting work.Yet find that in actual production process if the lip internal diameter of the tip diameter of miniature gears and seal ring is very approaching dimensionally, will cause in fitting process, the tooth top of miniature gears is easy to scratch the seal ring lip.In case the seal ring lip is scratched, steering box can't pass through air tight test, tightness test, thereby cause leakage of oil
To this problem, adopt the position of transposing bearing and seal ring to satisfy functional requirement usually, but the increase that will bring part sourcing cost and frock purchase cost thus.Therefore, under the prerequisite that guarantees normal performance of product and reliable quality, design the low valve packe structure of a kind of cost and adopt the rational installation method of a cover to become those skilled in the art's technical issues that need to address.
Summary of the invention
Technical matters first aspect to be solved by this invention is to provide a kind of steering machine rotary valve assembly, to overcome the defective that the convertible valve seal ring scratches easily in fitting process.
Technical matters second aspect to be solved by this invention is to provide a kind of installation method of above-mentioned steering machine rotary valve assembly.
A kind of steering machine rotary valve assembly as first aspect present invention, comprise valve packe and be included in miniature gears and bearing in the valve packe, with housing and be included in tooth bar in the housing, miniature gears in the described valve packe and bearing installation are in housing, tooth bar engagement in described miniature gears and the housing, also comprise a seal ring, it is characterized in that described seal ring is installed on the shaft shoulder of miniature gears root by a seal ring lining.
Installation method as a kind of steering machine rotary valve assembly of second aspect present invention comprises the steps;
1, a protecting sleeve is sleeved on the tooth portion of miniature gears;
2, seal ring lining and seal ring are sleeved on by protecting sleeve on the shaft shoulder of miniature gears root of rotary valve, take out protecting sleeve;
3, the miniature gears of valve packe is packed into together with seal ring lining and seal ring and can be finished fitting work in the housing.
Owing to be filled on the miniature gears by protecting sleeve during seal ring, so avoided side cut phenomenon with pinion gear teeth.The present invention has enlarged the Applicable scope of present standard valve packe, especially to adopting the valve packe of large diameter miniature gears.Secondly relatively adopt the rotary valve structure of bearing and seal ring transposition, this scheme can effectively reduce cost, has avoided the input of extra frock clamp.The raising of reliability once more, at large diameter miniature gears, adopt this scheme after this position steering box air tight test, tightness test qualification rate be increased near 100%, met design and production requirement.After passing through the fatigue experiment to steering box, every technical index of steering box all meets the requirements at last, and the steering box that this part is housed has simultaneously been finished the examination of client road, proves that this scheme is to meet original designing requirement fully!
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the local structure scheme drawing of rotary valve of the present invention;
Fig. 2 is the scheme drawing of installation method of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Referring to Fig. 1, a kind of steering machine rotary valve assembly, comprise valve packe 1 and be included in miniature gears 2 and bearing 4 in the valve packe 1, with housing 3 and be included in tooth bar 5 in the housing, miniature gears 2 in the valve packe 1 and bearing 4 are installed in the housing 3, tooth bar 5 engagements in miniature gears 2 and the housing 3, seal ring 22 is installed on the shaft shoulder of miniature gears 2 roots by a seal ring lining 21.
During installation, at first a protecting sleeve 6 is sleeved on the tooth portion of miniature gears 2; Seal ring lining 21 and seal ring 22 are sleeved on by protecting sleeve 6 on the shaft shoulder of miniature gears 2 roots of rotary valve, take out protecting sleeve 6; At last the miniature gears 2 of valve packe 1 is packed in the housing 3 together with seal ring lining 21 and seal ring 22, open the effect of guiding and location in the external diameter by seal ring lining 21 in process of press in and the process that is engaged in pressure of housing 3, thereby guarantee that seal ring 22 can correctly be pressed onto position accurately.Pass through adjustment in addition, can guarantee after having pressed, guarantee that seal ring lining 21 can not produce play up and down the degree of depth of housing 3.
Although invention has been described for the foregoing description, for the technical personnel of the industry, still can do multiple variation to present embodiment, therefore, every employing similar variation of the present invention all should be listed protection scope of the present invention in.
