Abstract
The utility model discloses a kind of cycloid type lubricating pump internal rotor, the Outside radius (R1) of internal rotor is 30mm, and root radius (R2) is 24.6mm.Internal rotor molded line of the present utility model connects nature transition, without cusp, thus makes oil pump smooth running, noise free.
Description
Technical field
The utility model relates to a kind of internal rotor of cycloid type lubricating pump.
Background technique
Cycloid type lubricating pump structure is simple, and volume is little, lightweight, and oil transportation amount is large.Cycloid rotor pump system adopts the structure of inner and outer rotors engagement, and the number of teeth is few, compact dimensions, just can not form Seal cage by other isolated components, and its number of spare parts is few.Therefore, the commercial Application of cycloid type lubricating pump is increasingly extensive.But in the prior art, due to unreasonable to the Profile Design of cycloid type lubricating pump internal rotor, rotor tooth top and tooth root place exist certain wedge angle, thus when causing oil pump to work, running is uneven steady, and noise is large.
Therefore those skilled in the art are devoted to develop the internal rotor of lubricating pump of a kind of molded line without wedge angle.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the internal rotor of lubricating pump of a kind of molded line without wedge angle.
For achieving the above object, the utility model provides a kind of cycloid type lubricating pump internal rotor, and the Outside radius of internal rotor is 30mm, and root radius is 24.6mm.
The beneficial effects of the utility model are: internal rotor molded line of the present utility model connects nature transition, without cusp, thus makes oil pump smooth running, noise free.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of the oil pump that the utility model one embodiment is applied.
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of cycloid type lubricating pump internal rotor, the Outside radius R1 of internal rotor is 30mm, and root radius R2 is 24.6mm.
As shown in Figures 2 and 3, the oil pump that this internal rotor is applied, comprises the pump housing 100 and pump cover 200 that are connected to each other, is provided with internal rotor 300 and the external rotor 400 of gerotor type in the pump housing 100.
Owing to having carried out appropriate design to the parameter of internal rotor, therefore make the molded line of internal rotor connect nature transition, without cusp, thus made oil pump smooth running, noise free.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
