Abstract
The utility model discloses a modified electric gate roller, which comprises an outer ring and a stud shaft. An inner hole of the outer ring is provided with two rows of raceways, two pairs of retainers are arranged between the outer ring and the stud shaft, two rows of steel balls are evenly distributed in the outer ring raceways and the two pairs of retainers so as to form connection of the outer ring in manner of rotation relative to the stud shaft, hole ends on two sides of the outer ring are respectively provided with a sealing ring and a rigid sealing ring which are mutually fastened, and simultaneously the end, close to the outer ring, of the stub shaft is a torque transmission shaft such as a double-flat shaft, a square shaft or a regular hexagonal shaft. The design adopting the outer ring in a drum-shaped structure, and the two pairs of retainers and the two rows of steel balls between the outer ring and the stud shaft leads the roller to be stable and smooth in the process of sliding along a guide rail, and also reduces the contact face between the roller and the guide rail so as to reduce friction and abrasion and prolong service life. Additionally, the torque transmission shaft on the stub shaft enables roller installation to be assisted by tools for operation, thereby being convenient and saving labor.
Description
Technical field
The utility model relates to the modified roller structure of a kind of electric door along the guide rail slippage.
Background technology
The electric door roller is the crucial requisite member of electric door along the guide rail slippage, no matter is translation door or stopping sliding door, singly opens or two opening, and all roller must be arranged, and just can make the keying of electric door slippage easily realization door, and the crucial effect that is roller.Roller is made of outer ring, bolt shaft, retainer, steel ball, sealed at both ends circle etc., but the outer ring circular surfaces of its roller is the face of cylinder, big with the guide rail contact surface of slippage, frictional force is big, easy to wear, this is an one, and it two is only to establish single track raceway and steel ball between outer ring and the bolt shaft, make that electric door running balance is poor, not steady.It three can't be by instrument when also existing roller install to connect, not only inconvenience but also require great effort.
Summary of the invention
Goal of the invention of the present utility model be to overcome the defective of prior art and provide a kind of make the electric door slippage steady, smooth and easy, can reduce wear, increase the service life and install modified electric door roller easy to connect.
Goal of the invention of the present utility model realizes by following technical proposal:
A kind of modified electric door roller, comprise outer ring, bolt shaft, the outer ring endoporus has raceway, and be provided with retainer between the bolt shaft, steel ball is divided equally in outer ring raceway and retainer, forms the relative bolt shaft in outer ring and is rotationally connected, and be respectively equipped with the sealing ring that is interlockingly connected with it and band rigid seal circle at outer ring two side holes end, described outer ring circular surfaces is cydariform, and endoporus is provided with double raceway, corresponding second mate's retainer and the double steel ball that is provided with relative installation; Bolt shaft is being a torque transmitting shaft near the outer ring end simultaneously.
Described band rigid seal circle coats steel disc by sheet rubber and forms.
Described torque transmitting shaft is two flat axles or square shaft or regular hexagon axle.
Compared with prior art, the utility model modified electric door roller is modified into drum organization with the cylindrical surface structure of outer ring circular surfaces on the original structure basis, the outer ring endoporus adopts double raceway, second mate's retainer and double steel ball, bolt shaft is processed into torque transmitting shaft, make this roller reach steady, smooth and easy along the guide rail slipping, can reduce the contact surface of roller outer ring circular surfaces and guide rail again, thereby reduce friction and wear and tear, increase the service life, install easy to connect, laborsaving.

Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the utility model contour structures schematic diagram.
The specific embodiment
Below in conjunction with above-mentioned accompanying drawing the utility model embodiment is specifically described again.
Shown in Fig. 1～3, modified electric door roller is installed in both sides, electric door lower edge, advances along the slippage of doorframe guide rail, comprise the outer ring 2 along the guide rail slippage, the circular surfaces of this outer ring is cydariform, guarantees and guide rail contact area minimum, wear-resistant with the power of reducing friction, increase the service life.Outer ring 2 endoporus have double raceway, and bolt shaft 7 between corresponding second mate's retainer 4 and the double steel ball 3 of being provided with, the slotted eye of second mate's retainer 4 is arranged installation relatively, double steel ball 3 totally 14 divide equally in outer ring 2 raceways and retainer 4, forming the relative bolt shaft in outer ring is rotationally connected flexibly, similar in appearance to bearing arrangement, the nose end sealing ring 1 and the band rigid seal circle 5 of snapping band turnup structure respectively in 2 both sides, outer ring simultaneously makes double steel ball etc. built-in.For this reason, both sides, outer ring nose end is processed into the inner groovy structure, so that open snapping after making two sealing rings utilize material elasticity to be pressed into, makes waterproof and anti-dust performance splendid.
Bolt shaft 7 of the present utility model is being processed into torque transmitting shaft near outer ring 2 ends, can be two flat axles or square shaft or regular hexagon axle 6, and present embodiment adopts regular hexagon axle 6.
Described sealing ring 1 is made with steel disc, and band rigid seal circle 5 coats steel disc by sheet rubber and forms.Not only guarantee rigidity but also have sealing.
The axle head of bolt shaft 7 is the thread segment of disjunctor, installs to connect usefulness, and interior hexagonal is processed in the end.
