Abstract
The utility model discloses a connecting device between gear pump and gear pump reduction gear belongs to extruder technical field. The connecting device between the gear pump and the gear pump speed reducer comprises a gear pump speed reducer, a crowned tooth coupling, a transition gear box, a crowned tooth coupling and a gear pump. The utility model provides an among the prior art connecting device after long-time work, because expend with heat and contract with cold's phenomenon can lead to structural part to take place deformation, the appearance of this deformation can lead to equipment wearing and tearing serious, reduces the life of equipment, increases production unit's manufacturing cost. Work as the utility model provides a connecting device utilizes the two-stage deformation compensation of universal wheel and cydariform tooth shaft coupling, has improved the life of equipment greatly, reduce cost.
Description
Technical Field
The utility model belongs to the technical field of the extruder, especially, relate to a connecting device between gear pump and gear pump reduction gear.
Background
The gear pump and the gear pump reducer of the extruder are used as core components of the extruder and play a vital role. Connecting device between gear pump and the gear pump reduction gear among the prior art all fixes subaerial, and this type of connecting device can lead to structural component to take place deformation because the phenomenon of expend with heat and contract with cold after long-time work, and the appearance of this deformation can lead to equipment wearing and tearing serious, reduces the life of equipment, increases production unit's manufacturing cost.
SUMMERY OF THE UTILITY MODEL
The utility model discloses after taking place expend with heat and contract with cold among the prior art, provide a gear pump and gear pump reduction gear between connecting device with deformation compensation function, this connecting device has long service life, low in production cost has a bit.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a connecting device between gear pump and gear pump reduction gear, connecting device include gear pump reduction gear 1, crowned tooth shaft coupling A2, transition gear box 3, crowned tooth shaft coupling B4 and gear pump 5. The gear pump speed reducer 1 is connected with the transition gear box 3 through a crowned tooth coupling A2, and the transition gear box 3 is connected with the gear pump 5 through a crowned tooth coupling B4.
Transition gear box 3 and gear pump 5 bottom be provided with the universal wheel, transition gear box 3 and gear pump 5 are placed on smooth working face, transition gear box 3 and gear pump 5 can move on the working face under the drive of thermal stress.
The utility model has the advantages that: when the connecting device works for a long time to generate thermal deformation, the transition gear box and the gear pump freely move on a working surface under the driving of thermal stress, and meanwhile, the crowned tooth coupling also has the function of compensating the deformation. The utility model discloses a two-stage deformation compensation of universal wheel and cydariform tooth shaft coupling has improved the life of equipment, reduce cost greatly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a gear pump speed reducer is included; 2. a crowned tooth coupling A; 3. a transition gear box; 4. a crowned tooth coupling B; 5. a gear pump.
Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the present invention is further described below with reference to the accompanying drawings in combination with the embodiments so that those skilled in the art can implement the present invention by referring to the description text, and the protection scope of the present invention is not limited to the embodiments.
