架子和小齿轮机构的伸缩气缸设计和制造

ABSTRACT:

伸缩气缸千斤顶是抬起重物的机制。千斤顶经常在升起车辆中使用，以便可以改变轮胎。许多类型的千斤顶通常与汽车一起使用，但也用于许多其他方式，包括工业机械甚至飞机。

The screw has a thread designed to withstand an enormous amount of pressure. This is due to the fact that it is generally holding up heavy objects for an extended amount of time. Once up, they normally self-lock so that they won’t fall if the operator lets go, and they hold up well to the wear of repeated use. If they are made with a ball nut, they will last longer because there is less friction created with this type of jack.

千斤顶可以升高并用插入千斤顶插入的金属杆降低。操作员用手顺时针方向将杆转向。这将螺丝转动千斤顶内并使其上升。螺丝抬起小金属缸和上方的平台。随着千斤顶上升，一旦插孔接触，就会放置在上面的任何东西。

Maximum jack lifts low level distance but we have to fabricate this model lift your needed distance, which is contain for rack and pinion drive in inner side of cylinder so, it is lift very high done it possible.

介绍:

Telescopic jacks have been around for decades. A recent teardown of a nine-story 1920s building in downtown Los Angeles uncovered an elevator operated by a water hydraulic unit and lifted by a telescopic jack. While such early designs were functional, in many cases, they were more trouble than they were worth. Non-synchronized telescopic jacks, for instance, had poor ride quality, since each stage acted independently of the other in either direction.

Today’s technology is far more advanced, and modern uses for telescopic jacks are far more versatile in that they satisfy the needs of a changing industry.

Telescopic jacks provide solutions for complicated space requirements, modernization, new construction designs and cylinder replacements, while also possessing intrinsic benefits like contamination reduction. Other advantages include no hole having to be drilled, and no ropes, governors or safeties. In some applications that may require partial embedment into the pit floor, a two-to four-stop hole-less telescopic jack would be recommended.

WORKING PRINCIPLE:

The telescopic cylinder jack it is one of the serious cylinder it is called stages. We have fabricate that telescopic cylinder jack three stages having, the rack and pinion connecting separate stages, which is connecting on lead screw for lifting purpose when you need the jack lifting condition drive the lead screw it is going up, by on rack and pinion drive.

Every stages connecting separate rack and pinion, it is serious connection and connecting through on lead screw, when it drives condition step by step going through up in stage by stage.
