Abstract
The utility model relates to the field of mechanical components, in particular to an expansion sleeve. The expansion sleeve comprises an inner cone ring. The inner cone ring is composed of a pipe part and a flange which is arranged on the end face of the pipe part. The outer surface of the pipe part is a circular conical surface, a locking screw through hole is formed in the flange, an inner cone ring opening is formed in the inner cone ring, an outer cone ring is arranged outside the inner cone ring and composed of a pipe part and a flange which is arranged on the end face of the pipe part, the inner surface of the pipe part is a circular conical surface, the conicity of the circular conical surface of the outer cone ring is same as the conicity of the circular conical surface of the inner cone ring, a locking screw hole is formed in the flange of the outer cone ring, an outer cone ring opening is formed in the outer cone ring, an outer ring is arranged outside the flange of the outer cone ring, an outer ring opening is formed in the outer ring, and a locking screw penetrates through the locking screw through hole and is matched with the locking screw hole. The expansion sleeve is simple in structure, and convenient to manufacture and install. The expansion sleeve can be installed only by being placed between a shaft and a hub and then screwing down the locking screw according to the required torque, and heating devices or cooling devices or pressurizing devices are not needed.
Description
Technical field
The utility model relates to the mechanical part field, particularly a kind of expansion set.
Background technique
In machinery, the rotating speed of prime mover output generally all can not meet the demand of working equipment, generally need to carry out speed and change.Simultaneously machinery is in a series of transmission conversion, except needing also to need the propeller boss connection being connected of axle and axle.Propeller boss commonly used is connected to connections such as adopting flat key or spline, adopts flat key or spline joint to connect as propeller boss, and reliability is higher.At needs, often dismantle occasion, adopt flat key or spline joint to bring certain trouble to dismantlement work.
The model utility content
The purpose of this utility model is: for the problems referred to above, provides a kind of expansion set, can overcome the problems referred to above, do not adopt flat key or spline joint, realize the propeller boss transmission, and also simple in structure, installation and removal are convenient.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of expansion set, is characterized in that comprising interior conical ring, and interior conical ring consists of with the flange that is arranged at the pipe end surface pipe section, and pipe section outer surface is conical surface, and the lock screw via hole is set on flange, and interior conical ring arranges interior conical ring opening; Interior conical ring peripheral hardware is put outer cone ring, and outer cone ring consists of with the flange that is arranged at the pipe end surface pipe section, and pipe section internal surface is conical surface, and tapering is identical with interior conical ring conical surface, and the lock screw screw is set on flange, and outer cone ring arranges the outer cone ring opening; The outer cone ring flange arranges outer ring outward, and the outer ring opening is set on outer ring; Lock screw passes the lock screw via hole and coordinates with the lock screw screw.
As preferably, interior conical ring circle appearance conical surface tapering is 1:50-1:5, and lock screw arranges 2-8 spare.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model expansion set is simple in structure, it is convenient to manufacture and install, and expansion set need not heat while installing, and cooling or pressurized equipment only need be put into expansion set in the gap of axle and hub, and lock screw moment is on request tightened and got final product.The utility model expansion set is when needs are dismantled, and only need unscrew lock screw just can conveniently unclamp the connection of axle and hub.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the A-A sectional view for Fig. 1.
Fig. 3 is the utility model schematic perspective view.
Mark in figure: 1-outer cone ring, conical ring in 2-outer ring, 3-, conical ring opening in 4-lock screw, 5-, 6-outer cone ring opening, 7-outer ring opening.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment one: with reference to Fig. 1, Fig. 2, a kind of expansion set, is characterized in that comprising interior conical ring 3, and interior conical ring 3 consists of with the flange that is arranged at the pipe end surface pipe section, and pipe section outer surface is conical surface, and lock screw 4 via holes are set on flange, and interior conical ring 3 arranges interior conical ring opening 5; The outer outer cone ring 1 that arranges of interior conical ring 3, outer cone ring 1 consists of with the flange that is arranged at the pipe end surface pipe section, and pipe section internal surface is conical surface, and tapering is identical with interior conical ring 3 conical surfaces, and lock screw 4 screws are set on flange, and outer cone ring 1 arranges outer cone ring opening 6; Outer cone ring 1 flange arranges outer ring 2 outward, and outer ring opening 7 is set on outer ring 2; Lock screw 4 passes lock screw 4 via holes and coordinates with lock screw 4 screws.
As preferably, interior conical ring 3 circle appearance conical surface taperings are 1:50-1:5, and lock screw 4 arranges 2-8 spare.
When in use, the pipe section of expansion set of the present utility model is put between the axle and hub gap need connected, then tightens lock screw 4 by certain moment, lock screw 4 when tightening, the distance of further outer cone ring 1 and interior conical ring 3.Outer cone ring 1 and interior conical ring 3 coordinate for conical surface, and outer cone ring 1 and interior conical ring 3 total thickness increase when lock screw 4 is tightened, and are connected with hub in order to reach axle.When needs are dismantled, unclamp lock screw 4, interior conical ring 3 is away from outer cone ring 1, and outer cone ring 1 and interior conical ring 3 total thickness reduce, and make axle and hub unclamp connection.
