Abstract
The utility model relates to a leak-proof connecting device for the lubricating oil pump-connecting pipeline of a tatra type automobile engine, composed of a sleeve pipe 1, an O-shaped ring 2, a threaded stud 3, a bend pipe 4, a clamp 5, a rubber pipe 6, flange plates 7, 8 and a straight pipe 9. The leak-proof connecting device can thoroughly solve the problem of the tatra engine that the connecting part of a crankshaft box and the lubricating oil pump leaks engine oil seriously. The device has the advantages of convenient assembly and maintenance, long service life, low cost, etc.
Description
The utility model relates to a kind of leakage-proof connecting that is used for Tatra type automobile engine oil pump connecting pipeline.
The oil pump of Tatra 815 types (T815) motor of being made by Czechoslovakia is the secondary gear formula, and it is installed in the crankcase outside, and oil sump tank then is contained on the oil sump.Pipeline from the oil sump tank to the oil pump is that steel pipe connects, and the connecting mode of two ends flange plate is the plane butt joint, and clamping bolt is for being screwed into formula, and pump case silk hole is a cast aluminium, and sealing gasket adopts paper washer.Owing to design and structural reason, the motor shear vibration that produces that is in operation causes bolt looseness, in crankcase and oil pump connection place machine oil often taking place and seriously leak outside, not only cause direct economic loss, and holds the machine looks for traffic safety and machine and cause very big influence.For addressing the above problem, prevent leakage of oil, the emergency measure of taking at present is to flange plate connection place, oil pump two ends at oil sump tank, the oil resisting rubber jointing sealing is replaced by in original paper washer sealing, be screwed into stud bolt in the silk hole of oil pump housing, use nut fastening again, but fail of the effect.
The purpose of this utility model provides a kind of oil pump connecting pipeline leakage protection device, utilizes this device can thoroughly solve Tatra h type engine h crankcase and the serious machine oil of oil pump point of attachment (oozing) problem that leaks outside.
The utility model is to realize like this.It is made up of sleeve pipe 1, " O " type ring 2, stud bolt 3, bend pipe 4, clamp 5, sebific duct 6, flange plate 7,8 and straight tube 9.Its number of assembling steps is as follows: sleeve pipe 1 φ 28 1 ends that " O " type ring 2 will be housed insert flange plate 7 center holes and from wherein bend pipe 4 is inserted in the below, and φ 30 1 ends are then in the insertion machine oil pump oil-sucking hole; With two stud bolts 3 oil suction of flange plate 7 and two-stage pump housing being connect dish is linked together; Similarly, the flange plate 8 that will be welded into one with straight tube 9 with stud bolt is connected in oil sump tank and connects on the dish; At last, sebific duct 6 two ends are linked to each other with straight tube 9 with bend pipe 4 respectively, and block with clamp 5.After connecting assembling and finish by above-mentioned steps, machine oil flows to the machine oil pipe by oil sump tank, the suction that produces during the work of twin-stage gear pump forms vacuum in connecting pipeline, machine oil is successively by straight tube 9, sebific duct 6, bend pipe 4 and sleeve pipe 1, enter the twin-stage gear oil pump, the service behaviour of vacuum effectiveness and pump is improved significantly, and can prevent the generation of oil pump joint oil leakage phenomenon effectively.
The utility model is reasonable in design, and is simple in structure, and sealability is reliable, can thoroughly solve the serious leakage problems of T815 h type engine h oil pump connecting pipeline machine oil, also has advantages such as assembling, easy to maintenance, long service life, cost be low, is suitable for extensive employing.
Fig. 1 is a general structure schematic representation of the present utility model.
Fig. 2 is clamp 5(a) and flange plate 7,8(b) structural representation.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
Sleeve pipe 1 one ends of the present utility model are φ 30, and the other end is φ 28, and long 18mm does with the 45# steel; " O " type ring 2 is the oil resistant rubber ring of φ 25 * 3; Stud bolt 3 is M10 * 60, material 45# steel; Bend pipe 4 and straight tube 9 are all φ 30, make straight tube 9 long 150mm with the 45# steel; Clamp 5 is garden hoop shape, and opening is tightened (see figure 2) with bolt, material 20Mn; Sebific duct 6 is φ 25 * 5, and long 200mm makes of oil resistant rubber; Flange plate 7,8(see Fig. 2) thick 10mm, there are a φ 28 center holes at the middle part, and respectively there are a φ 10 screw holes, material A3 in both sides.
Claims (3)
1, a kind of oil pump connecting pipeline leakage-proof connecting, form by sleeve pipe 1, " 0 " type ring 2, stud bolt 3, bend pipe 4, clamp 5, sebific duct 6, flange plate 7,8 and straight tube 9, it is characterized in that: sleeve pipe 1 φ 28 1 ends that " 0 " type ring 2 is housed insert flange plate 7 center holes and reach from below insertion bend pipe 4 wherein, then in the insertion machine oil pump oil-sucking hole, flange plate 7 usefulness stud bolts 3 connect dish with the oil suction of two-stage pump housing and link to each other φ 30 1 ends; The flange plate 8 usefulness stud bolts that are welded as a whole with straight tube 9 are connected in oil sump tank and connect on the dish; Connect with sebific duct 6 between bend pipe 4 and the straight tube 9 and with clamp 5 chuckings.
