CN2318447Y - Roller coupling - Google Patents

Abstract

The utility model discloses a roller coupling, which comprises end covers (1), an outer sleeve (2) and T-shaped inner sleeves (5). The two inner sleeves (5) are arranged on two shafts. The two end covers (1) are fixed with both ends of the outer sleeve through bolts, and the outer walls of the big ends of the inner sleeves (5) are provided with a plurality of arc-shaped slots (6) which equally divide the circumference, the inner wall of the outer sleeve (2) is provided with a plurality of arc-shaped slots (6) which are corresponding to the inner sleeves (5), and rollers (3) are arranged in holes which are formed by the inner sleeves (5) and the outer sleeve (2). The roller coupling has the advantages of simple manufacturing process, low manufacturing cost, compact structure, light weight, big angle of permissible deflection, big conveying torque compared with the couplings of the same kind, good lubrication condition and long service life, and is suitable for the installing of various mechanical shafts.

Description

A kind of roller coupling

The utility model belongs to the coupling field, a kind of coupling with middle roller of saying so more specifically.

The present coupling that uses, comparatively generally gear coupling.Processing technology complexity when producing gear coupling, the manufacture cost height, the inside and outside gear ring of gear coupling allows the angle little (θ≤30 ') of deflection, and lubrication effect is poor.

Chinese patent CN90215888 provides a kind of movable ball coupling, though there is inside and outside gear ring to allow advantages such as deflection angle is big, steel ball contacts for point with the semi-circle of inside and outside snare, and unit load is big when transmitting same torque, and transmitting torque is less.

The purpose of this utility model is for overcoming the deficiency of above-mentioned technology, a kind of surface of contact that increases roller and inside and outside curve bath is provided, improve torque delivery, allowing the big roller coupling of angle of deflection.

For reaching above-mentioned purpose, the utility model provides a kind of roller coupling, and it is formed by overlapping in end cap, overcoat, the T font, overlaps in two to be installed in respectively on two axles, and two end caps are connected and fixed with bolt and overcoat two ends.The outer wall of interior cover major part is provided with several curve baths of circumference in equal parts, and the inwall of overcoat is provided with and the corresponding several curve baths of interior cover, lays roller in the hole of interior cover and overcoat formation.

The roller of the utility model coupling is a cydariform.

The utility model coupling transmitting torque is bigger than similar coupling, allows deflection angle big, compact structure, in light weight, and processing technology is simple.

Accompanying drawing 1 is the example structure schematic representation that the roller coupling is used for the full-depth tooth coupling.Two end caps 1 are enclosed within on two axles that are assembled, and cover 5 is installed in respectively on two axles in the T font.Interior cover 5 major part outer walls are provided with several curve baths 6 of circumference in equal parts, overcoat 2 inwalls are provided with and interior cover 5 corresponding several curve baths 6, lay roller 3 in the hole that interior cover 5 and overcoat 2 form, the two ends of two end caps 1 at overcoat 2 are connected and fixed with bolt 4, coupling gets final product work.

Accompanying drawing 7 is example structure schematic representation that the roller coupling is used for half gear coupling.End cap 1 is enclosed within on the axle that is assembled, cover 5 is installed on the axle in the T font, interior cover 5 major part outer walls are provided with several curve baths 6 of circumference in equal parts, outer casing inner wall is provided with and interior cover 5 corresponding several arc grooves, in the hole that interior cover 5 and overcoat 2 form, lay roller 3, the end of end cap 1 usefulness bolt 4 with overcoat 2 is connected and fixed, and coupling gets final product work.

For increasing the surface of contact of roller 3 and curve bath 6, roller can be and is designed to cydariform.

Claims (2)

1. roller coupling, comprise cover (5) in end cap (1), overcoat (2), the T font, cover (5) is installed in respectively on two axles in two, two end caps (1) are connected and fixed with bolt (4) and overcoat (2) two ends, it is characterized in that the outer wall of interior cover (5) major part is provided with several curve baths (6) of circumference in equal parts, overcoat (2) inwall is provided with and the corresponding several curve baths of interior cover (5) (6), lays roller (3) in the hole that interior cover (5) and overcoat (2) form.

2. coupling according to claim 1 is characterized in that the cydariform that is shaped as of roller (3).
