Abstract
The utility model relates to a pulley wheel for a rail type telescopic door, which comprises a hub and a web, wherein the hub comprises a step-shaped cylindrical wheel spoke formed by integral stamping; the web is fixedly arranged on one side of the wheel spoke. The centers of the web and a side plate of the wheel spoke are provided with through holes through which a wheel shaft can penetrate. Due to the adoption of a structure that plates are stamped in a cold-working mode and connected to assemble the integral pulley wheel, the utility model reduces the machining allowance of a pulley wheel assembly with less material consumption, effectively reduces the self weight of the pulley wheel, and has the advantages of low cost, simple and convenient manufacture process for the pulley wheel, high productive efficiency, high machining precision, better electroplated fineness, beautiful appearance and high product grade.
Description
The utility model relates to a kind of pulley, the pulley that particularly a kind of rail formula retractable door is used.
Existing rail formula retractable door pulley generally adopts cast member to be processed into by operations such as turning, plating, and the cast member pulley turning allowance of this structure is big, and consumptive material is many, and the pulley deadweight that single-piece is made increases the cost height; The technology that pulley is made is complicated, long processing time, and machining accuracy is low, and the fineness of plating is poor, and appearance is not attractive in appearance.Chinese patent ZL95243486.5 (notification number CN2210971Y) discloses the rolling pulley of a kind of splayed double width plate, hot-working is rolling to form the pulley of this structure owing to adopting, process equipment is huge, the cost height, labour intensity is big, and production efficiency is low, and the chipping allowance of processing also reduces seldom, the precision of processing is not high yet, and range of application is narrow.
The purpose of this utility model provides a kind of low cost of manufacture, production efficiency height, and the machining accuracy height is electroplated the good rail formula retractable door stamping parts pulley of fineness.
The utility model comprises hub and disc, and wherein hub comprises that integrated punching is step-like column spoke, and disc is fixedly mounted on the side of spoke, and be provided with can be by the through hole of wheel shaft disc and spoke side plate center.
The utility model is owing to adopt plate cold working punching press to connect the structure that is combined into whole pulley, greatly reduce the allowance of pulley assembly, consumptive material is few, effectively reduces the deadweight of pulley, and cost is low, the pulley manufacturing process is simpler, convenient, fast, production efficiency is high, the machining accuracy height, the fineness of plating is better, and is specious, product specification is high, this step-like column spoke architecture can be widely used in the rail formula retractable door under the various frequent situations under pressure, and is practical.
Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
As shown in Figure 1, the utility model comprises hub 1 and disc 2, wherein hub 1 comprises that integrated punching is step-like column spoke, disc 2 is fixedly mounted on the side of spoke, the disc 2 fixedly mode of spoke side can be that above-mentioned disc 2 is a tight fit with spoke, and its periphery is gone out and inflexedly snapped in the flanging 22 of spoke side and be installed in the spoke by punching press is fastening; Also can be to be fixed on the spoke side by the mode of welding.And the center of the side plate of spoke and disc 2 is provided with can be by the through hole of wheel shaft.For making things convenient for the slip of pulley, the side plate of above-mentioned spoke is positioned at the central through hole position and stamps out inward recess 11, and the position that above-mentioned disc 2 is positioned at central through hole stamps out the indent deep hole 21 that can install bearing.
Claims (3)
1, a kind of rail formula retractable door pulley, it is characterized in that comprising hub (1) and disc (2), wherein hub (1) comprises that integrated punching is step-like column spoke, and disc (2) is fixedly mounted on the side of spoke, and be provided with can be by the through hole of wheel shaft disc (2) and spoke side plate center.
2, according to the described rail formula of claim 1 retractable door pulley, the side plate that it is characterized in that above-mentioned spoke is positioned at the central through hole position and stamps out inward recess (11), and the position that above-mentioned disc is positioned at central through hole stamps out the indent deep hole (21) that can install bearing.
3, according to the described rail formula of claim 1 retractable door pulley, it is characterized in that above-mentioned disc and spoke are tight fit, its periphery has been gone out inflexed flanging (22) and has been installed in the spoke by punching press is fastening.
