Abstract
The utility model relates to a pump shaft and paddle wheel hub installation structure of an axial flow pump. The installation structure comprises a pump shaft and a paddle wheel hub. The periphery of the flange at the end part of the pump shaft is provided with pump shaft holes. The end part of the paddle wheel hub is provided with paddle wheel hub holes corresponding to the pump shaft holes. The end part of the pump shaft is provided with two keyways. The end part of the paddle wheel hub is provided with two protruding keys in fit with the keyways. The protruding keys of the paddle wheel hub are disposed in the keyways of the pump shaft. The pump shaft is connected to the paddle wheel hub through bolts or screws that pass through the pump shaft holes and the paddle wheel hub holes. The original pump shaft end is provided with two keyways, the original paddle wheel hub end is provided with two protruding keys, and the keyways are in fit with the protruding keys. In the installation process, the protruding keys of the paddle wheel hub are disposed in the keyways of the pump shaft end. Bolts are used for fixation to complete the assembly process. The installation structure changes cylinder pin transmission torque into rectangular key transmission torque. Transmission torque is increased, service lifetime is prolonged, and operation is more reliable.
Description
Technical field
The utility model relates to the mounting structure of a kind of pump shaft and impeller boss, be specifically related to a kind of at two keyways of original pump shaft end processing, at original two protruding keys of impeller boss end processing, the mounting structure of pump shaft and impeller boss in the axial-flow pump of the two corresponding matching.
Background technique
The installation of at present general axial-flow pump pump shaft and impeller boss is all that bolt is connected, by straight pin transmitting torque, straight pin is arranged between pump shaft and impeller, because straight pin mounting hole is to join to process, all to arrive scene special device and process, pretty troublesome also very difficult.People transform this conventional construction by every possible means for this reason, improve its mounting process.
Fig. 1 is the structural representation that common pump shaft is connected with impeller boss at present, Fig. 2 is the structural representation of the pump shaft end in the structure that common pump shaft is connected with impeller boss at present, Fig. 3 is the sectional view of Fig. 2, Fig. 4 is the structural representation of the impeller boss in the structure that common pump shaft is connected with impeller boss at present, and Fig. 5 is at present common pump shaft and the structural representation of impeller boss assembling.Existing pump shaft end construction form and impeller boss end construction form be as Figure 1-5: the one group of pump shaft hole 5 that has circle distribution in pump shaft 2 end flange, also there is one group of impeller hub bore 6 with pump shaft hole 5 correspondences impeller boss 1 end, by bolt 3 by the two connection, there is the semicylindrical opening (401 and 402 in Fig. 2 and 4) that straight pin 4 is installed the two end, moment of torsion will lean on straight pin 4 to transmit, required precision is higher, is processed into so join at the two rear scene of on-the-spot installation.Scene needs the process equipments such as drilling machine, very inconvenient.
Model utility content
For the problems referred to above, it is a kind of at original two keyways of pump shaft end processing that main purpose of the present utility model is to provide, at original two protruding keys of impeller boss end processing, the mounting structure of pump shaft and impeller boss in the axial-flow pump of the two corresponding matching.
The utility model solves above-mentioned technical problem by following technical proposals: the mounting structure of pump shaft and impeller boss in a kind of axial-flow pump, described structure comprises pump shaft and impeller boss, the end flange of described pump shaft has one group of pump shaft hole of circle distribution, the end of described impeller boss has the one group impeller hub bore corresponding with pump shaft hole, the end of described pump shaft is processed with two keyways, two protruding keys that coordinate with keyway of end processing of impeller boss, the protruding key of impeller boss is installed in the keyway of pump shaft, by pump shaft and impeller boss, the two couples together through pump shaft hole and impeller hub bore to adopt bolt or screw.
In preferred embodiment of the present utility model: described pump shaft hole and impeller boss hole number are equal, number scope is 6-10.
Positive progressive effect of the present utility model is: the utility model is at original two keyways of pump shaft end processing, at original two protruding keys of impeller boss end processing, the two corresponding matching, is installed to the protruding key on impeller boss in the keyway of pump shaft end when installation, can complete assembling with bolt is fixing.The utility model is changed into square key transmitting torque by original straight pin transmitting torque, and transmitting torque strengthens, and extend working life, moves more reliable.The utility model is easy for installation, and all assembling sets all complete at manufacturing shop, has avoided the trouble of on-the-spot processing.The utility model has reduced installation cost, has shortened the installation time.
