(2) background technique
In road construction work, liquid bitumen in the asphalt mixing plant is carried and is sprayed, and pitch factory asphalt delivery, canned, discharging, all be unable to do without bitumenpump.The present pitch gear oil pump that adopts, the engagement between driving gear and the driven gear are the monodentate engagements, and the asphalt delivery amount is little, and noise is big, and the rate of putting is low, and load concentration, and bearing capacity is little, has reduced the working life of pump.
(3) summary of the invention
The technical problems to be solved in the utility model provides that a kind of asphalt delivery amount is big, noise is little, stable working, efficient height, the pitch gear oil pump of long service life.
The employing technological scheme is:
The pitch gear oil pump comprises the pump housing, motor, driving shaft, driven shaft, front cover, rear end cover and base.After loading onto circular tooth gear respectively on driving shaft, the driven shaft, pack in the pump housing, circular tooth gear on the driving shaft and the multiple tooth engagement of the circular tooth gear on the driven axle at the front and back ends difference fit on front cover and the rear end cover of the pump housing, and are fixed by bolts on the pump housing respectively.There are driving shaft bearing and driven shaft bearing in the front cover inboard, is provided with setting sleeve at driving shaft bearing liner, is equiped with active bearings in setting sleeve, in the driven shaft bearing, is lined with setting sleeve, is equiped with driven bearing in setting sleeve.Equally, driving shaft bearing and driven shaft bearing are arranged respectively in the rear end cover inboard, be equiped with setting sleeve and active bearings, passive bearing in two bearing supports respectively.The two ends of driving shaft and driven axle are supported by the active bearings and the passive bearing that are installed in forward and backward end cap inboard respectively.Driving shaft has axially extended stuffing box gland in the rear end cover upper edge, between stuffing box gland and the driving shaft stuffing box packing is housed, on driving shaft, be equiped with Gland, adjust the degree that compresses of Gland, can not only realize dynamic seal (packing), and rotate flexibly, in the pump housing bottom conduction oil is set and stores and the flowing space, and be connected with the deep fat source, constitute the conduction oil flow circuits by pipeline, on pipeline, can install control valve, the break-make and the flow direction of control conduction oil.Valve body is fixed on the base.Motor is fixed on the base, and motor output shaft is connected by coupling with the pump driving shaft.
Above-mentioned coupling adopts the shaft coupling sprocket wheel to connect, and is covered with protective housing, and the protective housing lower end is fixed on the base.
The utility model is owing to adopt Double circular arc gear drive, and enough facewidth can realize multiple tooth engagement, and every pair of tooth all has a plurality of contact pointss, and the contact points outer curvature radius is very big.Therefore, the Novikov gears with double circular arc tooth profiles of multiple spot engagement is little with the quantity delivered of straight-tooth wheel pump in the past, and noise is big, and efficient is low etc., and drawback is compared, and has very high contact strength, stable drive, and quantity delivered is big, and noise is little, the efficient advantages of higher.And make a contact become the line contact after the carrying running-in gradually, avoided the theoretic line contact of involute gear to making the receptance of alignment error, prevent load concentration, improved bearing capacity, the double circular arc tooth root is stronger, the flexural strength height.Point gearing does not exist each contact points of involute gear to have different Sliding velocitys, has improved transmission efficiency and working life.The utility model seals tightly everywhere, and the oil immersion packing filling is adopted in the revolution dynamic seal (packing), and is wear-resistant under the high temperature, good sealing effect.Pump housing bottom is provided with conduction oil and stores and the flowing space, to the pitch heating, guarantees that fed sheet of a media-pitch is in pump all the time and inhales on the temperature, is convenient to carry.
