Abstract
A passenger car windscreen wiper reduction box bottom shell comprises a shell body, an end cover used for fixing a motor is arranged on the shell body, a motor shaft hole is formed in the end cover, a circular cavity and a strip-type cavity are arranged in the shell body, the circular cavity can contain a worm wheel, the strip-type cavity is positioned at one side of the circular cavity and can contain a worm, the head portion of the strip-type cavity is communicated with the motor shaft hole, a support seat is arranged at the tail portion of the stripe-type cavity, a mounting groove is concavely arranged in the support seat and an opening of the mounting groove is towards the stripe-type cavity, and a glue injection hole is formed in the support seat and is vertically communicated with the mounting groove. The passenger car windscreen wiper reduction box bottom shell has the advantages that the structure mentioned above is adopted, the mounting groove is matched with the worm, and glue is injected into the mounting groove through the glue injection hole, so that the worm is firmly and reliably installed in the strip-type cavity, even if the worm operates for a long time the phenomenon that a nut is loose and fallen off does not exist, besides the outer end of the mounting groove is closed, and sealing performance is good.
Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of car windshield wiper speed reducer drain pan.
Background technique
Existing car windshield wiper speed reducer drain pan, mainly comprise enclosure body, this enclosure body is provided with the end cap for fixed electrical machinery, this end cap is provided with motor axis hole, be provided with the round chamber that can hold worm gear in the described enclosure body and be positioned at a side of this round chamber and the bar shaped chamber that can hold worm screw, the head in this bar shaped chamber is connected with described motor axis hole, and the afterbody in this bar shaped chamber runs through described enclosure body.When mounted, motor is fixed on the end cap, the end of worm screw in the motor shaft of motor passes motor axis hole and is installed in the bar shaped chamber links to each other, the other end of worm screw passes outside the enclosure body and by nut and is fixed, thereby worm screw is fixed in the bar shaped chamber, the worm gear that is meshed with worm screw is installed in the round chamber, cover at last lid and get final product, by the transmission of worm gear and worm screw, thereby realize slowing down.Because the end of worm screw is fixed on the enclosure body by nut, the worm screw long-term operation, nut is loosening dropping easily, causes worm screw fixing insecure, thereby affect the performance of speed reducer, and sealing is poor.
Summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides that a kind of simple in structure, fixation is reliable, the car windshield wiper speed reducer drain pan of good airproof performance.
The technical scheme in the invention for solving the technical problem is: a kind of car windshield wiper speed reducer drain pan, comprise enclosure body, this enclosure body is provided with the end cap for fixed electrical machinery, this end cap is provided with motor axis hole, be provided with the round chamber that can hold worm gear in the described enclosure body, and be positioned at a side of this round chamber and the bar shaped chamber that can hold worm screw, the head in this bar shaped chamber is connected with described motor axis hole, the afterbody in described bar shaped chamber is provided with supporting base, be concaved with the mounting groove towards described bar shaped chamber opening on this supporting base, also be provided with on the described supporting base and the perpendicular hole for injecting glue that is communicated with of described mounting groove.
Further, described enclosure body and described end cap are one-body molded, so that structure is compacter, can effectively save material, reduce fabricating cost.
The utility model when mounted, motor is fixed on the end cap, the end of worm screw in the motor shaft of motor passes motor axis hole and is installed in the bar shaped chamber links to each other, the other end of worm screw inserts in the mounting groove of supporting base, then injecting glue in from hole for injecting glue to mounting groove, thereby with solid and reliable being installed in the bar shaped chamber of worm screw, the phenomenon that had both made the worm screw long-term operation also not exist nut loosening to drop, and the outer end of mounting groove sealing, then good airproof performance is equipped with the worm gear that is meshed with worm screw in round chamber, cover at last lid and get final product, by the transmission of worm gear and worm screw, thereby realize slowing down.
The beneficial effects of the utility model are: adopt said structure, match with worm screw by mounting groove, and by hole for injecting glue injecting glue in the mounting groove, thereby with solid and reliable being installed in the bar shaped chamber of worm screw, the phenomenon that had both made the worm screw long-term operation also not exist nut loosening to drop, and the sealing of the outer end of mounting groove, good airproof performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of car windshield wiper speed reducer drain pan, comprise enclosure body 1, this enclosure body 1 is provided with the end cap 2 for fixed electrical machinery, this end cap 2 and described enclosure body 1 are one-body molded, this end cap 2 is provided with motor axis hole, be provided with the round chamber 3 that can hold worm gear in the described enclosure body 1, and be positioned at a side of this round chamber 3 and the bar shaped chamber 4 that can hold worm screw, the head in this bar shaped chamber 4 is connected with described motor axis hole, the afterbody in described bar shaped chamber 4 is provided with supporting base 5, be concaved with the mounting groove towards described bar shaped chamber 4 openings on this supporting base 5, also be provided with on the described supporting base 5 and the perpendicular hole for injecting glue that is communicated with 6 of described mounting groove.
The utility model when mounted, motor is fixed on the end cap 2, the end of worm screw in the motor shaft of motor passes motor axis hole and is installed in bar shaped chamber 4 links to each other, the other end of worm screw inserts in the mounting groove of supporting base 5, then injecting glue in from hole for injecting glue 6 to mounting groove, thereby with solid and reliable being installed in the bar shaped chamber 4 of worm screw, the phenomenon that had both made the worm screw long-term operation also not exist nut loosening to drop, and the outer end of mounting groove sealing, then good airproof performance is equipped with the worm gear that is meshed with worm screw in round chamber 3, cover at last lid and get final product, by the transmission of worm gear and worm screw, thereby realize slowing down.
