Abstract
The utility model relates to a combination oil seal of crank shafts of diesel engines, employing for a rear oil seal of crank shafts of a diesel engine 110. The utility model is substantially composed of a base plate, a main sealing lip and a dust proof auxiliary lip. The main sealing lip is stuck to the base plate on which the dust proof auxiliary lip is vulcanized. The utility model has the advantages of simple and compact structure, reliable sealing performance, and further the utility model is not easy to produce oil leakage. The utility model is convenient in installment and usage, is capable of being installed to the engine without twice installation, and does not influence the usage of users.
Description
The utility model relates to a kind of crankshaft of diesel engine combination oil seal, is used on 110 diesel engines as the bent axle Rear oil seal.
Before the utility model was made, in prior art, 110 diesel engines (6110,4110) bent axle Rear oil seal assembly mainly was made up of standard oil sealing and oil sealing base.Earlier the standard oil sealing is pressed in the oil sealing base, again they is installed to motor together and gets on.The bent axle combination oil seal spare complex structure of this kind structure is installed and used trouble, the oil spill rate height.
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple in structure, and sealing is reliable, is difficult for producing leakage of oil, and is easy to install, can be directly installed on the crankshaft of diesel engine combination oil seal on the motor.
Main solution of the present utility model is achieved in that it mainly is made up of substrate 1, the main lip 4 of sealing, dustproof secondary lip 3.Seal main lip 4 and be bonded on the substrate 1, the dustproof secondary lip 3 of sulfuration on the substrate 1.
Description of drawings:
Fig. 1 is the utility model structural representation:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model substrate 1 adopts the steel plate punching press to make, and its function is a skeleton as this device.Seal main lip 4 and adopt the filled polytetrafluoroethylenes compacting to form, its inwall is carved with the derotation thread groove, and it has contacting of broad with main shaft, when main axis rotation, can produce one strong to inner suction, can stop oily leaking.Sealing master's lip 4 directly is bonded on the substrate 1.Dustproof secondary lip 3 adopts rubber to make, and directly sulfuration is on substrate 1, and its major function is to prevent that extraneous dust is inhaled into.Use when installing and mix O type rubber seal 2, after substrate 1 is installed on the motor, make whole Sealing static sealing.
Compared with the prior art the utility model has the following advantages: 1, simple in structure, compact; 2, close Reliable, the difficult generation leakage of oil of sealing property; 3, easy to install, can be directly installed on the engine, do not have, Need secondary installing, do not affect the user and use.
Claims (2)
1, a kind of crankshaft of diesel engine combination oil seal is characterized in that adopting substrate (1), dustproof secondary lip (3), seals main lip (4) and forms, seals main lip (4) to be bonded on the substrate (1), and substrate (1) is gone up and vulcanized the secondary lip (3) that prevents dust.
2, crankshaft of diesel engine combination oil seal according to claim 1 is characterized in that described substrate (1) inwall is carved with the derotation thread groove.
