Abstract

The utility model discloses an inertial fly wheel of an exerciser, which is composed of a casing body and a centre shaft of revolution. The casing body is a circular hollow component, and the center of the casing body is provided with a center hole; most parts of the centre shaft of revolution is covered in the center hole of the casing body, and the extent section extending out of the casing body plane is a power connecting section. The casing body of the utility model is a hollow component, and the casing body can be made by sheet metal through pressing and welding; and by filling the metallic materials and other materials with different specific gravities in the hollow cavity, the fly wheels with the same shape can have different weight, and can operate stably without foreign sound, and can meet the different requirements on the inertial wheel of different exercisers. The higher precision can be got because the plate metal impact moulding is adopted, and the surface colour and luster is brighter after galvanization, and different marks as letter and designs can be impacted on the surface of the plate metal.

Description

The exercycle inertial flywheel

Technical field

The utility model relates to a kind of body-building apparatus, particularly relates to a kind of exercycle inertial flywheel.

Background technology

The inertial flywheel of commonly using mostly is cast iron and makes, and exists defectives such as roughness is lower, profile is not attractive in appearance, weight is heavier, cost is higher, stamp difficulty, and the neither convenience of production and transport, is not suitable for family and uses.

The utility model content

The purpose of this utility model be to provide a kind of good looking appearance, stamp easily, exercycle inertial flywheel that weight is lighter.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of exercycle inertial flywheel; It is made up of housing and revolution axis; Described housing is a hollow member, offers a centre bore at the center of housing; The major part of described revolution axis is nested with in the centre bore of housing, and its extension section of stretching out the housing plane is the power linkage section.

Described housing is a circular hollow member, offers a centre bore at the center of housing.

The power linkage section of described revolution axis is chain drive or belt transmission, and unidirectional transmission resistance or two-way transmission resistance.

Described housing is made up of loam cake, lower cover and Sealed casing pipe; Described loam cake and lower cover profile are all the disc-shaped component with centre bore, and loam cake and lower cover fasten mutually and be fixed together, and form an annular space between both inwalls; In the loam cake that described Sealed casing pipe insertion is fixed together and the centre bore of lower cover, it and loam cake, lower cover inwall form a totally enclosed annular space.

Described loam cake and lower cover are formed by metallic plate punching or plastics.

Described upper and lower covers is formed by connecting by metal or plastics.

After adopting such scheme, housing of the present utility model is a hollow member, housing available metal plate stamping, be welded, fill metal material or other material of different specific weight by empty inner chamber therein, realize that same profile flywheel has Different Weight, and operate steadily, do not have allophone, can satisfy of the different requirements of different body-building vehicles flying wheel.Owing to adopt the plate punch forming, can obtain higher sophistication, electroplate back outer surface color and luster light more, can satisfy the appearance requirement of high-grade exercycle, and can stamp out signs such as various literal, pattern in plate surface, have more novelty than traditional employing decals mode, and never drop-off, fade, lift up song.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment

As shown in Figure 1, the utility model is a kind of exercycle inertial flywheel; It is made up of housing 1 and revolution axis 2.

As Fig. 3, shown in Figure 5, described housing 1 is made up of loam cake 11, lower cover 12 and Sealed casing pipe 13.Described loam cake 11 and lower cover 12 profiles are all the disc-shaped component with centre bore, and loam cake 11 and lower cover 12 fasten mutually and be fixed together, and form an annular space 14 between both inwalls; In the loam cake 11 that described Sealed casing pipe 13 insertions are fixed together and the centre bore of lower cover 12, it and loam cake 11, lower cover 12 inwalls form a totally enclosed annular space 14, and this annular space 14 constitutes the hollow cavity of housings 1.Described loam cake and lower cover also can be the member of other shape, as: square, rhombus etc.

The major part of described revolution axis 2 is nested with in the centre bore of the Sealed casing pipe 13 of housing 1, and its extension section 21 of stretching out housing 1 plane is power linkage section 21, and this power linkage section 21 is sprocket wheel or belt pulley, is used for external power.

The loam cake 11 of present embodiment and lower cover 12 are formed by metallic plate punching, adopt the method (as shown in Figure 4) of full week welding that both are fixed together at both junction A; And then polish, electroplate.The utility model can directly stamp out required literal B, pattern C (as shown in Figure 2) or form recess G (as shown in Figure 6) as required when punching press on the sheet metal surface.

Loam cake 11 of the present utility model or lower cover 12 can be formed by metallic plate punching all, also can one (as: upper and lower covers) form with metallic plate punching or plastics, are formed by connecting with plastic material again, and perhaps upper and lower cover is injection molded by plastic material.The material that is filled in housing 1 hollow cavity can be because of the time send out nonmetallic materials 10 (as shown in Figure 6) such as expanded materials such as TM, sponge, the beautiful appearance of guarantor or stone, sand, rubber.
