Description

A kind of carriage

Technical field

This utility model relates to household implements technical field, is specifically related to a kind of carriage.

Background technology

A lot of plant equipment can be used slide mechanism, realize the linear sliding motion of some parts, if directly making two parts relative slidings can produce very big sliding-frictional resistance, need the parts dyskinesia slided, at present, it is common to adopt sliding bearing to realize the linear sliding motion of slide mechanism, Sliding bush is the critical piece of sliding bearing, being made up of special material and smooth surface, adopt hydrodynamic lubrication at slide unit with Sliding bush part in use, force of sliding friction is less.

The linear sliding motion adopting sliding bearing to be capable of less friction at present more, although bearing base part Technical comparing is ripe, especially rolling bearing, in all kinds of environment, almost used good transmission performance, but, sliding bearing technology is ripe not as rolling bearing, owing in use slide unit and Sliding bush are plane-plane contacts, although there being fluid lubricant, still can wear and tear the smooth surface of Sliding bush, so that the transmission performance of sliding bearing reduces, force of sliding friction increases, particularly when high temperature transmission or high-speed drive, you can there is abrasion in the short period in bearing shell, life-span is short.The smooth surface of one end Sliding bush occurs that trace weares and teares, and Sliding bush can lose efficacy at short notice, loses the slip transmission performance of routine, force of sliding friction increases, make linear slide difficulty, and now change sliding bearing and there is a need to shut-down dismounting, delay the duration and relatively costly.

Utility model content

The purpose of this utility model is in that: for the problem that the easy wear-out life of current slipping drive is short, it is provided that a kind of wear extent is less and the carriage of life-span length.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of carriage, including the limiting component that slide unit and at least three of rectilinear movement can rotate, the distribution of described limiting component is arranged on the both sides of the glide direction of described slide unit, each limiting component matches with described slide unit respectively, make described limiting component rolling when sliding of described slide unit, so, slide unit slides relative to the earth on the limiting component that can rotate, but being absent from relative sliding between slide unit and limiting component, slide unit is difficult to limiting component is caused sliding frictional wear；And, even if slide unit is because skidding the Micro-friction abrasion that limiting component causes local, owing between slide unit and limiting component being rolling transmission, the abrasion of limiting component has no effect on slide unit and rolls transmission with limiting component, slide unit remains able to do rectilinear motion when minimum frictional resistance, frictional force between slide unit and gag lever post is almost negligible, namely slide unit can under the effect of minimum frictional force linear slide, drive the kinetic equation loss that slide unit slides less, save the energy.

Additionally, limiting component distribution is arranged on the both sides of the glide direction of slide unit, so, it is possible to make slide unit be only capable of doing rectilinear motion, it is thus possible to prevent slide unit from coming off from limiting component, it is possible to make carriage more firm, work relatively reliable.

As preferably, the limiting component quantity of the glide direction both sides being arranged on described slide unit is identical and positioned opposite, and so, carriage runs more steady, and transmission performance is better.

As preferably, the pivot center of described limiting component is parallel to each other, and the pivot center of described limiting component is perpendicular to the direction of motion of described slide unit, and so, carriage is cheap for manufacturing cost, and runs more steady, and transmission performance is better.

As preferably, the surface configuration limited location groove of described limiting component, described limited impression is adaptive with the outer surface of described slide unit, so, it is prevented from slide unit to come off from limiting component, carriage can be made more firm, work relatively reliable, and, the contact area of limiting component and slide unit can be increased, thus reducing the contact stress of limiting component and slide unit, it is possible to reduce the wear extent of limiting component and slide unit, it is possible to improve service life further.

As preferably, the surface configuration of described slide unit has sliding recess, described sliding recess is adaptive with the outer surface of described limiting component, that is, described limiting component is provided with projection, this projection is adaptive with sliding recess, so, it is prevented from slide unit to come off from limiting component, carriage can be made more firm, work relatively reliable, and, the contact area of limiting component and slide unit can be increased, thus reducing the contact stress of limiting component and slide unit, the wear extent of limiting component and slide unit can be reduced, can improve service life further.

As preferably, the cross sectional shape of described limited impression and/or sliding recess is circular arc, so, simple in construction, low cost of manufacture, and run more steady, transmission performance is better.

As preferably, described limiting component is connected by gear pair with described slide unit, it is to say, described limiting component and described slide unit can engage each other, now limiting component is similar to gear, slide unit is similar to tooth bar, the connection of limiting component and slide unit is similar to the annexation of wheel and rack, so, it is possible to avoid slide unit relative limit members slides in the process slided, it is thus possible to avoid the abrasion on limiting component surface, it is possible to improve the life-span further.

In sum, owing to have employed technique scheme, the application provides the benefit that:

1, the life-span is high: slide unit is relative limit members slides not, and slide unit is difficult to cause the sliding frictional wear of limiting component, and the wear extent of limiting component is little, and the life-span of carriage is high；

2, frictional resistance is minimum: owing between slide unit and limiting component being rolling transmission, the abrasion of limiting component has no effect on slide unit and rolls transmission with limiting component, slide unit remains able to do rectilinear motion when minimum frictional resistance, and the frictional force between slide unit and gag lever post is almost negligible；

3, save the energy: slide unit can under the effect of minimum frictional force linear slide, drive slide unit slide kinetic equation loss less, save the energy.
