Description
Technical field
This utility model relates to a kind of needle bearing, particularly relates to the needle bearing of a kind of door and window trolley.
Background technology
In building doors and windows field, door and window trolley is one of important handware, and the needle bearing in door and window trolley is then the critical piece affecting door and window trolley serviceability.The needle bearing of currently used door and window trolley, due to unreasonable structure, the gap between adjacent needle roller is bigger, make roller inner wall abrasion serious, cause needle roller not revolve round the sun, cause roller and roller bearing eccentric wear serious, seriously reduce the service life of needle bearing, have impact on the serviceability of door and window trolley.
Utility model content
Problem to be solved in the utility model is to overcome the deficiency in background technology, the needle bearing of a kind of door and window trolley is provided, the needle bearing of this door and window trolley, currently used needle bearing structure is improved, decrease the gap between adjacent needle roller, make needle roller can normally revolve round the sun at work, improve the service life of needle bearing.
For solving the problems referred to above, this utility model takes techniques below scheme:
The needle bearing of a kind of door and window trolley of the present utility model, it is made up of roller, needle roller, roller bearing and pad, described roller is cylindrical, described roller centrally along being axially machined with through hole, described through hole is provided with roller bearing, being provided with 12 needle rollers between described roller bearing and roller vertically, described pad is arranged on the two ends of through hole through roller bearing.
Further, described pad is arranged in the stepped hole at through hole two ends, and the outer transverse plane of described pad flushes with the medial plane of roller.
Further, the external peripheral surface of described roller is machined with annular arc groove.
Compared to prior art, the beneficial effects of the utility model are:
The needle bearing of a kind of door and window trolley of the present utility model, it is preferably used in plastic-steel pulley, and preferably 12 needle rollers are evenly distributed between the inwall of roller bearing and roller through hole, the gap between adjacent needle roller is made to be minimized, guarantee that needle bearing is at work, needle roller can normally revolve round the sun, and makes roller and roller bearing uniform wear, thus improves the service life of needle bearing；The needle bearing of a kind of door and window trolley of the present utility model, the most suitably adds the diameter of roller bearing simultaneously, enhances the intensity of roller bearing, thus also improve the bearing capacity of door and window trolley.
The needle bearing of a kind of door and window trolley of the present utility model, is arranged on pad in the stepped hole at through hole two ends, and makes the outer transverse plane of pad flush with the medial plane of roller, it is ensured that the good looking appearance of needle bearing；The needle bearing of a kind of door and window trolley of the present utility model, the external peripheral surface at roller is machined with annular arc groove, decreases force of rolling friction, improves the ride comfort that needle bearing rolls.
The needle bearing of a kind of door and window trolley of the present utility model, smart structural design, improve service life and the bearing capacity of needle bearing, this utility model has the advantages such as simple in construction, easily manufacture, easy for installation, low cost, life-span length.

Description of reference numerals: 1-roller, 2-needle roller, 3-roller bearing, 4-pad, 11-through hole, 12-annular arc groove.
Detailed description of the invention
As depicted in figs. 1 and 2, the needle bearing of a kind of door and window trolley of the present utility model, it is made up of roller 1, needle roller 2, roller bearing 3 and pad 4, described roller 1 is cylindrical, described roller 1 centrally along being axially machined with through hole 11, being provided with roller bearing 3 in described through hole 11, be provided with 12 needle rollers 2 between described roller bearing 3 and roller 1 vertically, described pad 4 is arranged on the two ends of through hole 11 through roller bearing 3.
Described pad 4 is arranged in the stepped hole at through hole 11 two ends, and the outer transverse plane of described pad 4 flushes with the medial plane of roller 1.
The external peripheral surface of described roller 1 is machined with annular arc groove 12.
Compared to prior art, the beneficial effects of the utility model are:
The needle bearing of a kind of door and window trolley of the present utility model, it is preferably used in plastic-steel pulley, and preferably 12 needle rollers 2 are evenly distributed between the inwall of roller bearing 3 and roller 1 through hole 11, the gap between adjacent needle roller 2 is made to be minimized, guarantee that needle bearing is at work, needle roller 2 can normally revolve round the sun, and makes roller 1 and roller bearing 3 uniform wear, thus improves the service life of needle bearing；The needle bearing of a kind of door and window trolley of the present utility model, the most suitably adds the diameter of roller bearing 3 simultaneously, enhances the intensity of roller bearing 3, thus also improve the bearing capacity of door and window trolley.
The needle bearing of a kind of door and window trolley of the present utility model, is arranged on pad 4 in the stepped hole at through hole 11 two ends, and makes the outer transverse plane of pad 4 flush with the medial plane of roller 1, it is ensured that the good looking appearance of needle bearing；The needle bearing of a kind of door and window trolley of the present utility model, the external peripheral surface at roller 1 is machined with annular arc groove 12, decreases force of rolling friction, improves the ride comfort that needle bearing rolls.
The needle bearing of a kind of door and window trolley of the present utility model, smart structural design, improve service life and the bearing capacity of needle bearing, this utility model has the advantages such as simple in construction, easily manufacture, easy for installation, low cost, life-span length.
Should be noted that; the foregoing is only preferred embodiment of the present utility model, be not limited to the present embodiment, all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
