In the position structure of above-mentioned automobile crane oil sealing, the quantity of described clamping block is provided with four.Simultaneously, the quantity of mounting groove and position are corresponding with clamping block on the oil sealing on the locating slot, and clamping block can be installed in the locating slot correspondingly.
In the position structure of above-mentioned automobile crane oil sealing, the periphery wall of described oil sealing contacts with the inwall of above-mentioned mounting groove.Interference fit between oil sealing and the end cap mounting groove, so the periphery wall of oil sealing tightly pastes and on the inwall of mounting groove.
In the position structure of above-mentioned automobile crane oil sealing, the upper surface of described oil sealing and the upper surface of above-mentioned locating slot are positioned on the same horizontal plane.
In the position structure of above-mentioned automobile crane oil sealing, the inner ring diameter of described oil sealing is less than or equal to the diameter of above-mentioned bent axle.Through such design, guarantee to have good sealing effect between oil sealing and the bent axle, thereby avoid the lubricant oil on the bent axle can be from front end and back end axially not the spilling of bent axle along bent axle.
In the position structure of above-mentioned automobile crane oil sealing, described oil sealing is a rubber parts.
Compared with prior art, the position structure of this automobile crane oil sealing has the following advantages:
1, the position structure of this automobile crane oil sealing is through being provided with protruding from inside to outside clamping block on the periphery wall of oil sealing; On crank shaft oil seal mounting groove inwall, offer and clamping block shape, the corresponding locating slot in position; Through the caking block interference is connected in the locating slot; Prevent this oil sealing eccentric and circumferential rotation in mounting groove, make the fixing and location of crank shaft oil seal more reliable.
2, the position structure of this automobile crane oil sealing makes crank shaft oil seal when mounted; Be installed in the locating slot through clamping block; Under the prerequisite of design that guarantees locating slot and machining accuracy, can guarantee to have higher coaxality after crankshaft installed is to the motor, thereby avoid crank shaft oil seal and bent axle decentraction; Make to install to become convenient, sealing becomes reliable.
3, just on existing crank shaft oil seal and end cap, carrying out local improvement can effectively evade the oil seal failure risk to the position structure of this automobile crane oil sealing, changes little and brings notable results, and is fit to extensively promote the use of.
