Post by SchultzMy Sentra (1994) is making a LOUD droning noise when I drive. The noise
level increases the faster I drive.
My mechanic said that it was a 5th gear problem, and that my generation
Sentras often have such problem. He wants $900 to rebuilt the tranny--he
says a failure
would be "catestrophic".
Does this sound right?
Thanks.
Skills for reducer selection
There are many kinds of reducers in the market while ach reducer has its own function. Different reducer is suitable for different industries, and the structure of different reducer is also different. Although the diversification of the reducers reflect technical retrofit and upgrade. But at the same time for buyers, choose a suitable reducer for their own industry is also slightly more important, because once you choose the wrong machine, it will bring d immeasurable damage, even worse, once there is an impact on work efficiency, it may bring more damage and a series of chain reactions. Thus, for the selection of the reducer, there is also a certain theoretical basis, as well as some skills. Here, the article will explain in detail for you to choose a suitable reducer and some skills.
Methods and Approach
The first step we go to buy a reducer, determining the purpose of our purchase. For the classifications of reducers in refinement, reducers can be divided into gear reducer, worm reducer, and so many small categories. But for us, we can change another way. Generally, we must first determine to buy imported reducers or domestic reducers, because, as different manufacturers, it has a set of their own definition. If we do not understand this, it may bring trouble to the following work.
Secondly, we should have a technical drawings of the reducer structure or the type of reducer. Because when we get the various parameters of the reducer, it can be better analysis the application suit for our production or not. Here, we need to have a wealth of theoretical knowledge on our understanding of the reference parameters to investigate. This requires a lot of accumulation, also need a certain amount of experience. Requires that we must continue to learn the technology, in the purchase of gear reducer, we must pay special attention to the daily maintenance and maintenance of gear reducer, regular use of gear box cleaning and maintenance machine can better help us to extend the service life of the reducers.
We need to understand some of the reducer parameters, what parameters need to know? Here will be a detailed explanation. What is the proofread of the thermal power of reducers? Is the temperature of the surrounding environment. This is one of the data we need to analyze, as a reducer, it should have a motor, how much is the exactly number of the motor, we need to do in-depth analysis. In addition, how is the safety factor of the reducer?, we can get a reliable guarantee or not? It is the most important thing, must not be ignored. There is the gear reducer on what equipment to use, and the use of it may be some of the results, but also absolutely not careless. We also need pay attention to the axial force and the axial force of the output shaft of the reducer.
