Description
Technical field
The utility model relates to a kind of coupling, particularly relates to filling industry pump coupler in a kind of concreting machinery.
Background technique
When exporting, adopt the power of prime mover (like motor) coupling to connect usually.Coupling in transferring power as take place axial float can produce transmission excessive noise, vibrations steadily in addition too much axial float make high speed rotary coupling and bell jar or Oil pump flange end face interference friction and damage coupling and oil pump.
In concreting machinery; Usually coupling that designs or select for use and motor output shaft and oil pump input shaft means of fixation are that Cock screw or lock screw are fixed, but are transmitting high-power and the variable power frequency big, only depend on Cock screw to be difficult to limit the axial locking of coupling when being easy to generate the concrete pumping equipment power of shake.Because coupling is the vibrations of transmitting power all the time and bearing big frequency; Will inevitably produce excessive axial float after coupling work a period of time causes axle sleeve and axle to disconnect; It is red to make the friction of Oil pump flange end face high speed rotary burnt by high temperature, damages coupling, oil pump bearing and sealing.Therefore need after a period of time bell jar is pulled down in machine works, the inspection coupling is readjusted coupling and is connected the gap, adopts this coupling to delay work and mistakes and part dismounting inconvenience.
The model utility content
The utility model technical problem to be solved provides the filling industry pump coupler that a kind of transferring power is steadily reliable, quick and easy for installation, can effectively prevent the coupling axial float.
For solving above technical problem; The utility model provides following technological scheme: a kind of filling industry pump coupler; Comprise axle sleeve 1, elastomer 7, axle sleeve 28, said axle sleeve 1 is provided with convexity and the groove that cooperatively interacts with axle sleeve 28 opposing end faces, is provided with the interior gear teeth at protruding and groove inwall; Said elastomer 7 is provided with the outer gear teeth, is arranged between convexity and the groove of axle sleeve 1 and axle sleeve 28 and is meshed with the axle sleeve 1 and the interior gear teeth on the axle sleeve 28; Radially be furnished with lock screw 11 and Cock screw 9 respectively on said axle sleeve 1 and the axle sleeve 28; In said axle sleeve 1 or axle sleeve 28, have at least endoporus one end of an axle sleeve to be provided with step.
The endoporus of said axle sleeve 1 and output shaft adopt the spline connecting sleeve to be contained on the output shaft; Step end face at said axle sleeve 1 is provided with the pressing plate 4 that contacts with step; Bolt 5 passes the end face of pressing plate 4 spinnings at said output shaft, connects said axle sleeve 1, output shaft fixing.
Said axle sleeve 28 cooperates through flat key and is connected with input shaft, and said Cock screw 9 radially passes axle sleeve 28 and contacts with flat key on the input shaft.
In the utility model; With motor outputting power to oil pump (filling industrial pump) is example, and oil pump is fixedly installed on the bell jar 3 through bolted flange, promotes to the oil pump direction vertically with axle sleeve 1; Make axle sleeve one 6 end faces withstand on the oil pump shaft shaft shoulder; Again pressing plate 4 is pressed on the step of inner splined hole in the coupling axle sleeve, tights a bolt 5, again lock screw 11 usefulness torque spanners are tightened.Axle sleeve 28 is pushed to suitable distance to motor direction vertically, and this distance assembles the gap decision of reserving between the back by axle sleeve 1 and axle sleeve 28, and the gap generally is decided to be 3～5mm.Again Cock screw 9 is tightened the locking motor reel, the rotating motor axle makes the gear teeth meshing on axle sleeve 1 and axle sleeve 28 and the elastomer 7 through the observation hole on the bell jar 3 again.
Reach the oil pump input shaft from power warp beam sleeve 28, elastomer 7, the axle sleeve 1 of motor output shaft transmission; Because the concrete pumping equipment operating mode is complicated; Pulsatile impact is big, and the variable power frequency is big, and axle sleeve 1 receives pulsatile impact power will inevitably produce axial float vertically.Repeatedly experiment draws under the situation that only adopts lock screw 11 locking axle sleeves 1; Lock screw 11 can become flexible under pulsatile impact power, make axle sleeve 1 vertically play and with bell jar 3 internal surface interference friction the high temperature that arrives damages coupling and oil pump end-face seal ring and leakage of oil.Employing is tightened pressing plate 4 with bolt 5 and is withstood on oil pump output shaft end face; Make coupling axle sleeve 1 can not produce the axial float displacement with respect to oil pump shaft; Bell jar 3 and axle sleeve 1 near inwall on be provided with and step trough that axle sleeve one 6 sizes are fit to; Strengthened the gap of axle sleeve 1, can produce under the situation of small axial displacement, prevented that axle sleeve 1 and bell jar 3 inwalls from producing interference on one 6 on axle sleeve with bell jar 3.Be arranged at elastomer 7 between axle sleeve 1 and the axle sleeve 28 play a part transferring power and adjustment radially, axially loaded imbalance and bumper and absorbing shock.
From the above mentioned: the related a kind of filling industry pump coupler transmission of the utility model is steadily reliable, noise is little; Can effectively prevent coupling because damage coupling and the oil pump end-face seal ring that axial float causes; And convenient for installation and maintenance quick, can be widely used in the concreting machinery.
