Abstract
The utility model discloses a pressure welding structure of a portal crane bearing support. The pressure welding structure comprises a bearing support and a bearing, wherein the bearing is arranged inside an axle hole of the bearing support and is tightly matched with the axle hole; and the contact part of the axle hole at the bottom surface of the bearing support and the bearing is provided with a pressure welding limiting mechanism which is concave inwards. The pressure welding structure is simple and convenient to manufacture, the production efficiency under the condition of ensuring mechanical strength is improved, and the production cost is saved.
Description
Technical field
The utility model relates to the elevator field, relates in particular to a kind of elevator door closing mechanism bearing support.
Background technique
Bearing block assembly is the critical component on the elevator door closing mechanism, is formed by two bearings and a bearing support crimping.These parts are installed on the motor mounting plate of door motor system, middle bearing cooperates with gearing shaft, transmission shaft one end is installed motor transmission gearwheel, the other end is installed the magnet ring small gear, the magnet ring small gear cooperates with synchronous band, thereby the power of electric system passed to be with synchronously, drive the folding of door cutter, drive cage door and Room gate switch.The existing bearing holder assembly is a kind of to be to adopt injection molding, and this type of bearing support intensity is low, easily be distorted distortion or damage, and reduce mechanical life; Also having a kind of is with round steel machining moulding, or after being cast as flange plate-like blank earlier, each fitting surface is carried out the machining moulding again, make loaded down with trivial details, the processing technology complexity, manufacturing efficiency is low, the cost height.
The model utility content
The utility model aims to provide an arbor bearing crimping structure, and is simple in structure, easily manufactured, enhances productivity under the situation that guarantees mechanical strength, saves production cost.
For achieving the above object, the utility model is realized by the following technical solutions:
The disclosed door of the utility model arbor bearing crimping structure comprises bearing support, bearing; Described bearing be installed in the axis hole of bearing support and with its drive fit, it is spacing that the axis hole of described bearing support bottom surface and bearing contacting part are provided with the crimping that caves inward.
Preferably, described crimping is spacing to be had a plurality ofly, and presses the axis hole circumference uniform distribution of bearing support.
Further, described bearing has two, is installed in successively in the axis hole of bearing support.
Preferably, described bearing is deep groove ball bearing.
Preferably, described bearing support is zinc alloy.
Further, described bearing support is provided with mounting hole, and the bottom surface of bearing support also is provided with locating column.
The disclosed door of the utility model arbor bearing crimping structure guaranteeing that bearing support has under the prerequisite of better intensity, has been simplified manufacturing process greatly, and die casting is once namely plastic, has removed the machining of back from; Bearing and bearing support assemble the back and adopt crimping spacing, have also just saved the inwall machined grooves at bearing support, have removed the use of circlip for hole simultaneously from; Simple and reliable for structure, easy to process, enhance productivity, save production cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1-bearing support, 2-bearing, 3-mounting hole, 4-locating column, 5-crimping are spacing.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the disclosed door of the utility model arbor bearing crimping structure comprises bearing support 1, bearing 2; Bearing 2 be installed in the axis hole of bearing support 1 and with its drive fit, the axis hole of bearing support 1 bottom surface and bearing 2 contacting parts are provided with the crimping that caves inward spacing 5.
Preferably, crimping spacing 5 has a plurality of, and presses the axis hole circumference uniform distribution of bearing support 1.
Further, bearing 2 has two, is installed in successively in the axis hole of bearing support 1.
Preferably, bearing 2 is deep groove ball bearing.
Preferably, bearing support 1 is zinc alloy.
Further, bearing support 1 is provided with mounting hole 3, and the bottom surface of bearing support 1 also is provided with locating column 4.
The utility model bearing support adopts the zinc alloy material, makes with the die casting mode, by once-through.The zinc alloy fusing point is low, and easily die cast is not inhaled iron during die casting, is not stained with mould, and is can die casting complex-shaped, the precision part that wall is thin, and casting surface is smooth.Therefore, the bearing support of producing with zinc alloy diecasting had both guaranteed part strength, had removed the machining of back again from, had simplified manufacturing process.Bearing and bearing support assemble the back and adopt crimping spacing, have removed the use of end ring from, have also just saved the inwall machined grooves at bearing support simultaneously, have removed the use of circlip for hole from.Crimping herein is spacing, choose several points along the axis hole circumference uniform distribution at the bearing support end face exactly, with mould with the disposable certain depth that is pressed into of these several points, thereby the bearing support inwall of this end is tightened bearing outer ring, with firm being fixed in the bearing support of bearing.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
