Description

A kind of new gear for auto pump

Technical field

The utility model relates to gear, particularly a kind of new gear for auto pump.

Background technique

The gear structure that uses on the auto pump is simple, generally be provided with an axis hole in discoidal main body exactly, around main body, be provided with some tooth bars, the patent No. is 201020572128.2 1 kinds of gears that are used on the auto pump, mainly be to adopt the material-saving hole that is provided with some circles in disc-shaped body, although this design has alleviated the weight of gear and has saved material, but destroyed the integrity intensity of gear, this is economical with materials and the weight reduction that reaches on the basis that reduces gear quality, lose more than gain, damage such as the corresponding part that therefore makes automobile, produce maintenance expenses, just run counter to design itself.

So be necessary automobile is used for the further technological innovation of gear structure of water pump.

The model utility content

The purpose of this utility model is for the defective of prior art and deficiency, provide a kind of simple in structure, a kind of new gear for auto pump reasonable in design, easy to use, it adopts the gear middle part is provided with hollow shape, bulk strength and the quality of gear have been guaranteed like this, saved again material and alleviated weight, served multiple; It is lightweight, integrity intensity high, economical with materials has prolonged working life.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of new gear for auto pump described in the utility model comprises gear disk shape body, axis hole and tooth bar, and described gear disk shape body center is provided with axis hole; Evenly be provided with several tooth bars around the described gear disk shape body; It also comprises the annular hollow band, and described gear disk shape body middle part is provided with the annular hollow band.

Further, described annular hollow band cylindrical is equal to the distance of axis hole to gear disk shape body outer end distance and annular hollow band inner circle; Described distance is: 2.2cm.

After adopting said structure, the utility model beneficial effect is: its employing of the utility model is provided with hollow shape with the gear middle part, has guaranteed like this bulk strength and the quality of gear, has saved again material and has alleviated weight, serves multiple; It is lightweight, integrity intensity high, economical with materials, has prolonged working life.
