Description
Technical field
The invention belongs to deceleration device technical field, particularly relate to a kind of gear motor reducing gear, there is this motor subtract
The cleaning brush of speed mechanism and include the cleaning car of this cleaning brush.
Background technology
Generally, cleaning car can install one for clean cleaning brush, spray water to clean, it is to avoid dust
Flying upward, and be provided with gear motor reducing gear cleaning in brush, common gear motor reducing gear mostly is integral type
Structure, such as schematic diagram 1.
This gear motor reducing gear includes Gearbox 1 ', the case lid 2 ' being arranged on Gearbox 1 ', directly
The motor 3 ' being installed on case lid 2 ' and rotating shaft 30 ', directly processing the little gear 4 ' that motor 3 ' is upper and end is unsettled and with
The gear wheel 5 ' being arranged in rotating shaft 30 ' coordinates.Directly processing on motor 3 ' axle head due to little gear 4 ', this motor 3 ' does not has
Single protecgulum is also directly installed on reduction box case lid 1, and the end of little gear 4 ' is in vacant state rather than installation
On Gearbox 1 ', so, when needs increase motor 3 ' power time, can only by lengthen motor 3 ' entire length, as
This setting will cause the length of rotor to increase, and its mechanical strength can be the longest more poor；Additionally, due to the diameter of motor 3 ' cannot
Increasing, and cause the position that can not be suitable for confined space limiter stage high power requirements, product coverage is little.
In existing cleaning brush gear motor reducing gear, the sealing structure of sparge pipe is as in figure 2 it is shown, existing tooth
In wheel motor reducing gear, when installing or dismantle sparge pipe 6 ', Gearbox 1 ' can only be opened and install or change,
Reason is that sparge pipe 6 ' is to use nut 7 ' to be locked at case lid 2 ' inside (to have step at the fixing screw thread of sparge pipe 6 ', can keep off
The outside of case lid 2 ' motor-end, inside nut 7 ' is locked on the fixing screw thread of sparge pipe 6 '), can only fix from inside, as
Shown in Fig. 2: open total cartridge screw, split out Gearbox 1 '；Split out gear wheel 5 '；The O taken out on sparge pipe 6 ' (is not marked
Show)；Dismantle nut 7 '；Sparge pipe 6 ' could be extracted to the outer motor side of case lid 2 '.Said gear motor reducer structure is structurally
Not fully taking into account sealing property, the sealing of sparge pipe 6 ' is poor, and water is back to Gearbox easily by sparge pipe 6 '
1 ' is internal, causes decelerator to lose efficacy.And, sparge pipe 6 ' is installed complex, will take whole reduction box internally installed apart
Could realize, also be difficult to the most after sale safeguard, main is that after cost is high.
In conjunction with Fig. 1 and Fig. 2, internal in order to prevent water to be back to Gearbox 1 ', in the water inlet end shaft core of rotating shaft 30 '
Inside is provided with O groove, and O is contained in this groove and is enclosed within sparge pipe 6 ', with the threaded tip on sparge pipe 6 ' be press-fitted with
Playing waterproof function, axle head does not has water-proof function in the internal also outer end of Gearbox 1 ' yet, and O slightly weares and teares, and water will
It is likely to enter Gearbox 1 ' internal, to cause Gearbox 1 ' to lose efficacy.
Existing gear motor reducing gear will cause it to there is problems in that gear motor slows down due to self structure
Mechanism noise is big, sparge pipe 6 ' poor sealing performance, easily leaks, sparge pipe 6 ' installation difficulty, and after-sales service cost is high, due to merit
Rate size affects and makes the coverage series of problems such as little grade of product.
