Abstract

The utility model relates to a novel coupler used on hydraulic pump, which includes an outer connecting sleeve and two inner connectors; the novel coupler used on hydraulic pump is characterized in that the two ends of the inside of the outer connecting sleeve are respectively provided with an inner gear; the outside of each inner connector is provided with an outer gear matched with the inner gear of the outer connecting sleeve; the inner connector is inserted in the outer connecting sleeve; the hole of the inner connector is also provided with a key groove; and the inner connector is provided with a jackscrew. Both the outer connecting sleeve and the inner connectors of the structure are made of nylon materials; when a motor runs, the motor and an oil pump shaft buffer the vibration brought by the assembling error between shafts in a certain scope, without affecting the service life of the motor and the oil pump simultaneously. The coupler adopts engaging and connecting of inner gear and outer gear, has the advantages of large driving torque and stable transmission, etc, and meets the requirement of not causing loosening and clearance volume during the long term running of the hydraulic pump. In a word, the novel coupler used on hydraulic pump has the advantages of simple structure, convenient use, compact cooperation, safety, reliability, etc.

Description

A kind ofly be used for novel coupler on the oil hydraulic pump
Technical field
The utility model belongs to link manufacturing technology field, particularly relates to a kind of novel coupler on the oil hydraulic pump that is used for.
Background technique
Hydraulic power unit mainly is made up of fuel tank, motor, oil pump at present, motor shaft is connected with axle sleeve mutually with oil pump shaft, is processed with the keyway that mates with motor shaft and oil pump shaft in the axle sleeve, is provided with jackscrew at the two ends of axle sleeve, jackscrew one end withstands on the motor shaft, and the other end withstands on the oil pump shaft.Because oil pump is in the long-term running; when when motor shaft and oil pump shaft are adjusted, having the lower margin of error decentraction or motor pump loosening; can cause the wearing and tearing of axle sleeve loosening; make that key and keyway in the axle sleeve are constantly loosening at the volley; and then cause the bigger noise of generation when unit turns round, cause axle sleeve heavy wear to cause shutdown when serious.Therefore the axle sleeve weak point of making of steel part in working life causes heavy wear very soon in case become flexible.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to use, cooperate compact, the safe and reliable novel coupler on the oil hydraulic pump that is used for.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind ofly be used for novel coupler on the oil hydraulic pump, comprise outer connecting sleeve and two interior connecting heads, it is characterized in that: the inboard two ends of described outer connecting sleeve are shaped on internal tooth respectively, the outside of described each interior connecting head is equipped with the external tooth with outer connecting sleeve internal tooth coupling, interior connecting head is inserted in the outer connecting sleeve, interior connecting head endoporus also is processed with keyway, and described interior connecting head is provided with jackscrew.
The utility model can also adopt following technical measures:
Described outer connecting sleeve and interior connecting sleeve all adopt nylon material to make.
Advantage and the good effect that the utlity model has are: because the utility model adopts nylon material to replace existing metal connecting sleeve, utilized the pliability of nylon material, motor and oil pump shaft cushion the vibration that brings owing to the assembly error between axle and the axle within the specific limits when motor rotation gets up, and also can not influence the working life of motor pump simultaneously; The utility model has adopted inside and outside tooth engagement to connect, it is big to have driving torque, advantages such as transmission is stable, the long-term operation of having satisfied oil hydraulic pump can not cause loosening and gap value yet, the utlity model has advantages such as simple in structure, easy to use, that cooperation is compact, safe and reliable in sum.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model three-dimensional exploded view.
Among the figure: 1, outer connecting sleeve; 1-1, internal tooth; 2, interior connecting head; 2-1, external tooth; 2-2, keyway; 3, interior connecting head; 4, jackscrew; 5, pump shaft; 6, motor shaft; 7, key.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind ofly be used for novel coupler on the oil hydraulic pump, comprise outer connecting sleeve 1 and two interior connecting heads (2,3), outer connecting sleeve 1 and interior connecting head (2,3) all adopt nylon material to make.The inboard two ends of described outer connecting sleeve 1 are shaped on internal tooth 1-1 respectively, the outside of described each interior connecting head 2 is equipped with the external tooth 2-1 with outer connecting sleeve 1 internal tooth 1-1 coupling, interior connecting head 2 is inserted in the outer connecting sleeve 1, interior connecting head 2 endoporus also are processed with keyway 2-2, and described interior connecting head 2 is provided with jackscrew 4.
During use: respectively interior connecting head (2,3) is inserted on pump shaft 5 and the motor shaft 6, and it is fastening by jackscrew 4 and diaxon, interior connecting head (2,3) with both sides inserts in the outer connecting sleeve 1 respectively then, and by key 7 connections, the external tooth of connecting head matches with the internal tooth of interior connecting sleeve in guaranteeing when plug-in mounting.Therefore the utility model has utilized the pliability of nylon material, and motor and oil pump shaft cushion within the specific limits because the vibration that the assembly error between axle and the axle is brought when motor rotation gets up; The utility model has adopted inside and outside tooth engagement to connect, it is big to have driving torque, advantages such as transmission is stable, the long-term operation of having satisfied oil hydraulic pump can not cause loosening and gap value yet, the utlity model has advantages such as simple in structure, easy to use, that cooperation is compact, safe and reliable in sum.
