Abstract
The utility model discloses a dustproof and waterproof reinforced direction machine, which belongs to the technical field of automobile steering gears. A technical key point is as follows: the dustproof and waterproof reinforced direction machine comprises a shell in which a gear bar and a gear rack are arranged, wherein one end of the gear rack is engaged with the gear bar; the other end of the gear rack penetrates through the shell to extend to the external side of the shell; the gear bar is arranged in the shell by a bearing; a threaded cover is arranged between the gear bar on the external side of the bearing and the shell; and an oil seal is arranged between the external surface of the threaded cover and the gear bar, wherein a protective cover is arranged on the gear bar on the external side of the shell; the protective cover is arranged on the periphery of the end part of the shell; and the threaded cover and the oil seal are both positioned in the protective cover; and the utility model aims at providing the dustproof and waterproof reinforced direction machine with compact structure and good use effect; and the dustproof and waterproof reinforced direction machine is used for automobile steering gears.
Description
Technical field
The utility model relates to a kind of motor turning and uses the direction machine, more particularly, relates in particular to a kind of dustproof and waterproof enhancement mode direction machine.
Background technology
In automobile steering system, direction machine assembly is contained in the car body outside, and in order to guarantee its ability long-term use, it is inner just must to prevent that dust and water from getting into assembly.Existing direction machine assembly, the dustproof and waterproof at the ratch place generally is through oil sealing sealing and be coated with aquaseal at the threaded cap inner tooth part realizes leak free.But, because the difference of vehicle usage condition exists the part oil sealing aging; Cause the not enough shortcoming of sealing; Cause water and dust approach axis machine assembly inner, make the inner tooth bar of direction machine assembly get rusty, have some setbacks when turning to; Fluency when influencing motor turning is when serious even can cause traffic accident.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of compact conformation, result of use good dust-proof waterproof enhancement mode direction machine are provided.
The technical scheme of the utility model is achieved in that a kind of dustproof and waterproof enhancement mode direction machine, comprises housing, in housing, is provided with ratch and tooth bar; One end of said tooth bar and ratch engagement, the other end passes housing and extends to hull outside; Described ratch is arranged in the housing through bearing; Be provided with threaded cap between ratch outside bearing and the housing; Be provided with oil sealing between described threaded cap outside face and the ratch; The ratch of wherein said hull outside is provided with protective cover, and described protective cover is arranged on the periphery of shell end, and described threaded cap and oil sealing all are positioned at protective cover.
In the above-mentioned dustproof and waterproof enhancement mode direction machine, be coated with the butter layer on the described protective cover inwall.
The utility model covers threaded cap and oil sealing through in the ratch periphery protective cover being set after adopting said structure.It plays the effect of a double seal with threaded cap and oil sealing.Exterior rainwater and dust drop on the cover, drop on the ground along the protective cover outer wall.Greatly reduce and reduced the possibility of water and dust approach axis machine, the service life that can improve direction machine assembly.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of Fig. 1 middle shell and ratch junction.
Among the figure: housing 1, ratch 2, tooth bar 3, bearing 4, threaded cap 5, oil sealing 6, protective cover 7.
The specific embodiment
Consult illustrated in figures 1 and 2ly, a kind of dustproof and waterproof enhancement mode direction machine of the utility model comprises housing 1, in housing 1, is provided with ratch 2 and tooth bar 3; One end of said tooth bar 3 and ratch 2 engagements, the other end passes housing 1 and extends to housing 1 outside; Described ratch 2 is arranged in the housing 1 through bearing 4; Between the ratch 2 in bearing 4 outsides and housing 1, be provided with threaded cap 5; Be provided with oil sealing 6 between described threaded cap 5 outside faces and the ratch 2, on the ratch 2 in housing 1 outside, be provided with protective cover 7, described protective cover 7 is arranged on the periphery of housing 1 end; Described threaded cap 5 all is positioned at protective cover 7 with oil sealing 6, and the approach axis machines such as exterior water and dust that effectively prevent are inner.Further, on protective cover 7 inwalls, be coated with the butter layer, butter make when ratch 2 rotates and the friction of the housing 1 of direction machine very little, can not produce different sound.
