Description
Technical field
The utility model relates to cycloid rotor pump part field, specially a kind of cycloid rotor pump rotor.
Background technique
Cycloid rotor pump is called cycloid gear pump, is made of pinion gear (rotor) and internal gear (stator).Two gears
It is cycloid gear, pinion gear only than an internal gear few tooth.Since inner and outer rotors are multi-tooth meshings, which forms several close
Seal volume.Cycloid rotor pump has many advantages, and such as compact-sized, small in size, part is few, and revolving speed may be up to 10000r/mim, fortune
It is dynamic steady, noise is low, and volumetric efficiency is higher etc..Because of the plurality of advantages of cycloid rotor pump, it is widely used automobile, drags
In the hydraulic system of the various kinds of lubricating oil such as machine drawing pump and electronic injection gasoline engine, diesel engine and precision machine tool and engineering machinery.But
It is since the requirement to cooperation precision is high, rotor difficulty in actual processing is larger, according to traditional process for machining,
Difficulty of processing is big, and the utilization rate of material is not high.Serious waste of resources, and to the assurance of precision deficiency, yields is not high,
Certain obstruction is caused to the promotion and popularization of cycloid rotor pump, therefore is badly in need of a kind of cycloid rotor pump rotor and is asked to solve this
Topic.
Utility model content
The utility model provides a kind of cycloid rotor pump rotor, can effectively solve to mention in above-mentioned background technique due to right
Cooperate the requirement of precision high, rotor difficulty in actual processing is larger, according to traditional process for machining, difficulty of processing
Greatly, and the utilization rate of material is not high.Serious waste of resources, and to the assurance of precision deficiency, yields is not high, turns to cycloid
The problem of promotion and popularization of son pump cause certain obstruction.
To solve the above-mentioned problems, the utility model provides the following technical solutions: a kind of cycloid rotor pump rotor, including master
Body is provided with crescent moon arc slot in the main body, arc-shaped gear is provided between the crescent moon arc slot, is provided on the inside of the main body
Floral axis hole, the side in the floral axis hole are provided with floral axis tooth socket, and the side of the floral axis tooth socket is provided with pin groove.
Preferably, the quantity of the crescent moon arc slot is six.
Preferably, the quantity of the arc-shaped gear is six.
Preferably, the main body, crescent moon arc slot, arc-shaped gear, floral axis hole, floral axis tooth socket, pin groove pass through powder metallurgy
Technique is integrally formed manufacture.
Compared with prior art, the utility model has the beneficial effects that the utility model is scientific and reasonable for structure, use is safe
It is convenient:
Rotor is manufactured by powder metallurgical technique, and compared to conventional machining process means, the utilization rate of material is higher, efficiency
Production cost that is higher, and can be greatly reduced, reduces the waste of material, while effectively reducing difficulty of processing, the essence of manufacture
Du Genggao improves its cooperation precision with stator, can effectively improve the service life of cycloid rotor pump.
