Abstract
The utility model discloses an improved steel gear structure, which comprises a steel gear base body, wherein the steel gear base body is provided with gear teeth which are annularly and uniformly distributed in the circumferential direction, the side surface of the steel gear base body is integrally formed with a reinforced nylon layer, the upper surface and the lower surface of the steel gear base body are respectively screwed with a fixed retaining sheet, the edge part of each fixed retaining sheet is provided with fixed retaining teeth which are matched with the gear teeth of the steel gear base body, and a contour line of the fixed retaining teeth is positioned between a contour line of the gear teeth and an outer contour line of the reinforced nylon layer. The improved steel gear structure has the advantages that the reinforced nylon layer is integrally formed on the side surface of the steel gear base body in an injection molding way, and the fixed retaining teeth are used for blocking the reinforced nylon layer from falling down from the side surface of the steel gear base body through the fixed retaining teeth; and in the engaged transmission process, the two engaged gears are in direct contact through the surface reinforced nylon layer, the noise is effectively reduced by the reinforced nylon layers, meanwhile, the work load is buffered by the reinforced nylon layer, and the service life of the gear is further prolonged.
Description
Technical field
The utility model relates to the gear structure technical field, relates in particular to a kind of improved type steel gear structure.
Background technique
As a kind of very important kind of drive, gear drive has been widely used in various machinery; Wherein, existing gear drive generally adopts steel gear to carry out engagement driving, though the steel gear can guarantee integral intensity, yet is easy to produce noise in the process of transmission, and the flank of tooth of the gear teeth of steel gear also is easy to wearing and tearing occur, and working life is shorter.
Summary of the invention
The purpose of this utility model is to provide a kind of improved type steel gear structure at the deficiencies in the prior art, noise and long service life that this improved type steel gear structure produces in the time of can reducing engagement effectively.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of improved type steel gear structure includes the steel gear matrix, and the steel gear matrix is provided with and is the equally distributed gear teeth of circumference ring-type, and the side surface of steel gear matrix is one-body molded the enhancing nylon layer; The upper surface of steel gear matrix and lower surface are screwed with fixedly catch respectively, fixedly the edge part of catch is provided with the fixed stop tooth with the gear teeth of steel gear matrix coupling, and the profile line of fixed stop tooth is between the outer contour of the profile line of the gear teeth and enhancing nylon layer.
The beneficial effects of the utility model are: a kind of improved type steel gear structure described in the utility model, it includes the steel gear matrix, the steel gear matrix is provided with and is the equally distributed gear teeth of circumference ring-type, and the side surface of steel gear matrix is one-body molded the enhancing nylon layer; The upper surface of steel gear matrix and lower surface are screwed with fixedly catch respectively, fixedly the edge part of catch is provided with the fixed stop tooth with the gear teeth of steel gear matrix coupling, and the profile line of fixed stop tooth is between the outer contour of the profile line of the gear teeth and enhancing nylon layer.Strengthen nylon layer and adopt the injection moulding mode to be shaped in the side surface of steel gear matrix, fixedly catch stops that by the fixed stop tooth enhancing nylon layer comes off from the side surface of steel gear matrix; In the process of engagement driving, two direct geareds of engagement strengthen nylon layer and can reduce noise effectively by the enhancing nylon layer contact on top layer, simultaneously, strengthen nylon layer and can also cushion operating load, and then increase the service life.
Description of drawings
Utilize accompanying drawing to come the utility model is further detailed below, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the local enlarged diagram of " A " shown in Figure 1 position.
In Fig. 1 and Fig. 2, include:
1---steel gear matrix 11---gear teeth
2---strengthening nylon layer 3---are catch fixedly
31---the fixed stop tooth.
Embodiment
Come the utility model is described below in conjunction with concrete mode of execution.
As depicted in figs. 1 and 2, a kind of improved type steel gear structure includes steel gear matrix 1, and steel gear matrix 1 is provided with and is the equally distributed gear teeth 11 of circumference ring-type, and the side surface of steel gear matrix 1 is one-body molded the nylon layer 2 of enhancing; The upper surface of steel gear matrix 1 and lower surface are screwed with fixedly catch 3 respectively, fixedly the edge part of catch 3 is provided with the fixed stop tooth 31 with the gear teeth 11 coupling of steel gear matrix 1, and the profile line of fixed stop tooth 31 is between the outer contour of the profile line of the gear teeth 11 and enhancing nylon layer 2.
Need explain further that strengthen nylon layer 2 and adopt the injection moulding modes to be shaped in the side surface of steel gear matrix 1, fixedly catch 3 stops that by fixed stop tooth 31 enhancing nylon layer 2 comes off from the side surface of steel gear matrix 1; In the process of engagement driving, two direct geareds of engagement strengthen nylon layer 2 and can reduce noise effectively by enhancing nylon layer 2 contacts on top layer, simultaneously, strengthen nylon layer 2 and can also cushion operating load, and then increase the service life.
Comprehensive above-mentioned situation the utlity model has the advantage of the little and long service life of noise as can be known.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
