Abstract

The utility model relates to a watt-hour meter graphite bearing counter. A bend frame is provided with a character axle, a transmission axle, a column-shaped first shaft and a second shaft. One side of the bend frame is provided with a T-shaped stopper, and while, the other side is provided with an end cover. The character axle is provided with a bottom wheel, a middle wheel and a top wheel. The transmission axle is provided with a transmission wheel. The second shaft is provided with a C bit gear and a D bit gear. The column-shaped first shaft is provided with an A bit worm wheel, a B bit gear and a gear stopper. The column-shaped first shaft, the bend frame and the end cover are cooperatively provided with a column-shaped graphite bearing. The utility model has the advantages of simple structure, low cost, small and stable friction moment, small alteration, etc., and the utility model increases the light-load eligibility rate of the watt-hour meter and prolongs the service life.

Description

Watt-hour meter graphite bearing counter

The utility model belongs to the counting mechanism technical field, relates in particular to be used for indication counter directly perceived mechanism count results.

The counter that uses in watt-hour meter at present is equipped with jewel bearing on its curved frame, I axle two ends axle journal is conical, and two conical axle journals of I axle are placed in the jewel bearing, and I axle and jewel bearing are centre support.Adopt the bearing and the centre support mode of this material and structure fabrication, owing to be easy to wearing and tearing after the long-time use of jewel bearing, after the heavy wear, axial, radial play between I axle and the jewel bearing increase, the moment of friction increase of counter also non-steady state occurs, variation increases, and makes that the watt-hour meter error increases, the underloading qualification rate reduces, the shortening in serviceable life.Another kind of watt-hour meter counter, although the structure of jewel bearing and I axle two ends axle journal is changed into cylindrical, still there is the major defect of aforementioned counter in this counter.

The purpose of this utility model is to overcome the shortcoming of above-mentioned watt-hour meter counter, provide a kind of simple in structure, cost is low, moment of friction is little, the watt-hour meter counter of stable performance, long service life.

For achieving the above object, the solution that the utility model adopts is: curved frame is provided with print wheel shaft, transmission arbor wheel, I axle, II axle, is provided with T shape stop in a side of curved frame, side is provided with end cap in addition.Wheel, great wheel in the end wheel, 3 or 4 are installed on print wheel shaft, 4 or 5 power wheels are installed on power axle, C position gear and D position gear are installed on the II axle, A position worm gear, B position gear, two ends are installed on the I axle stop also is installed, the I axle graphite bearing that matched with curved frame and end cap.

I axle of the present utility model and graphite bearing are cylindrical.

The utility model is compared with watt-hour meter jewel bearing counter, has advantages such as simple in structure, that cost is low, moment of friction is little, moment of friction is stable, variation is little, has improved the underloading qualification rate of watt-hour meter and has prolonged serviceable life.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the local amplification profile at I position among Fig. 1.

Below in conjunction with drawings and Examples the utility model is further described.

In Fig. 1,2, print wheel shaft 2, power axle 3, cylindrical I axle 13, II axle 10 are housed on curved frame 4, at the left side of the curved frame fastening T shape stop 1 of screw fastener, T shape stop 1 is used to prevent that print wheel shaft 2, power axle 3, II axle 10 from deviating from from curved frame 4, with the fastening end cap 9 of screw fastener, be used to prevent that print wheel shaft 2, power axle 3, cylindrical I axle 13, II axle 10 from deviating from from curved frame on the right side of curved frame 4.At the left end of print wheel shaft 2 end wheel 5, a right-hand member are installed a great wheel 8 is installed, wheel 6 in being equipped with between end wheel 5 and the great wheel 8, the counter of 5 bit digital is equipped with in 3 takes turns 6, the counter of 6 bit digital is equipped with in 4 takes turns 6, is marked with from 0 to 90 numeral at the cylindrical outer surface of end wheel 5, middle wheel 6, great wheel 8.Power wheel 7 is installed on power axle 3, the counter of 5 bit digital is equipped with 4 power wheels 7, the counter of 6 bit digital is equipped with 5 power wheels 7, between end wheel 5 and the middle wheel 6, between middle wheel 6 and the middle wheel 6, rotation between middle wheel 6 and the great wheel 8 all comes transmission by power wheel 7, from right to left, great wheel 8 is rotated a circle, first power wheel 7 of the right rotates, take turns 6 rotation numerals (36 °) in first on the right of driving, the right in first wheel 6 rotate a circle, second right power wheel 7 rotates, and drives in the second right wheel 6 numeral (36 °) that moves in turn, by that analogy.A C position gear 11(gear wheel is installed on II axle 10) and a D position gear 12(pinion wheel), the tooth engagement on tooth on the D position gear 12 and great wheel 7 cylindrical outer surfaces.At B position gear 14 of the right side of cylindrical I axle 13 fixed installation, A position worm gear 15 of left side fixed installation,

B position gear

14 and 11 engagements of C position gear, the worm mesh of A position worm gear 15 and watt-hour meter, match with an end-journal of cylindrical I axle 13 what be that riveting is contained in that cylindrical graphite bearing 17, other end axle journal on the curved frame 4 match is that riveting is contained in the cylindrical graphite bearing 17 on the end cap 9, in the inboard of the curved frame 4 of an end of cylindrical I axle 13 and the inboard of other end end cap 9 tooth shelves 16 are installed respectively, are used to reduce the axial string momentum of cylindrical I axle 13.
