In the ideal principle of gear transmission, if it is assumed that the two gears undergo pure rolling without any sliding at the pitch point and the gears themselves are regarded as rigid bodies, then theoretically, there should be no efficiency loss in gear transmission. However, in the actual real…
Cycloidal pinwheel reducers have a series of obvious disadvantages, and some of them, such as the high cost issue, are quite prominent. Some of these disadvantages happen to be the advantages of involute few-tooth difference reducers. The specific manifestations are as follows: First of all, cycloidal pinwheel reducers have strict…
When judging the quality of gears, the accuracy grade of the tolerance group is an important reference indicator. The following are examples for your illustration: Example 1: 7 — 6 — 6 GM GB10095 – 88 Here, “7” indicates the accuracy grade of the first tolerance group; the first “6”…
I need to achieve a bevel gear transmission with a shaft intersection angle ∑ of 90°, and it is required to have a high bearing capacity, frequent forward and reverse rotations, and a very compact structure size. Then, is it more appropriate to use spiral bevel gears? However, will reverse…
In a worm and worm gear transmission system, simply changing the transmission ratio of the worm and worm gear does not necessarily effectively reduce the wear of the worm gear if it wears out too quickly. The problem of the relatively fast wear rate of the worm gear can be…
When dealing with the tricky problem of motor vibration and noise, there are currently several practical and effective methods as follows. The first one is vibration reduction measures. Focusing on the source of vibration generation, by using advanced and scientific treatment methods, the amplitude of vibration waves is effectively reduced.…
In terms of the selection of (reducers), Shanghai Dianmai Transmission provides you with the following suggestions: First of all, reducers with a reduction ratio close to the ideal one should be selected as much as possible. The calculation method of the reduction ratio is: Reduction ratio = Rotational speed of…
(Planetary gear reducer) operates based on the principle of gear reduction. In its internal structure, there is a gear at the fixed axis position, which we call the central gear, also often known as the sun gear. Around the sun gear, there are a type of special gears that not…
In the field of mechanical lubrication, “engine oil” is a broad general term, referring to the lubricating oil used in various machines. However, usually when we mention engine oil, we more often refer to the engine oil specifically designed for gasoline and diesel engines. The characteristics of engine oil focus…
Among the numerous transmission equipment in modern industry, (gear reducers) occupy an important position with their outstanding performance and wide applicability. The gear reducer is an external meshing involute helical cylindrical gear reducer produced in strict accordance with the national professional standard ZBJ19004. It plays a key role in many…
