Abstract
The utility model discloses an axle push shaping apparatus and self-lubricating bearings employed by the axle push shaping apparatus. The axle push shaping apparatus comprises push shaping fixing shafts, which are disposed in a parallel manner for forming a push shaping cavity having a square axial section. The push shaping fixing shafts are all sleeved with push shaping bearings which can rotate around the push shaping fixing shafts; and lubricating layers are disposed along the contact inner walls of the push shaping bearings and the push shaping fixing shafts. The utility model also discloses the self-lubricating bearings, which are equipped with SF-2 layers made of SF-2 material on the inner walls. The bearings in the axle push shaping apparatus provided by the utility model are provided with the lubricating layers on the inner wall surfaces, with the lubricating layers being the SF-2 layers, which are made of the SF-2 material and are equipped with a plurality of internally concave cavities, thereby enabling long-term use without frequent oiling after being oiled once, having the advantages of strong abrasive resistance, strong carrying capacity and long service lifetime, and reducing production cost largely.
Description
Technical field
The utility model relates to axletree and makes the field, relates in particular to a kind of axletree side of pushing away device.
Background technology
Along with the raising of the level of the productive forces, the automobile transportation becomes one of main mode of freight transportation, and trailer is an indispensable carrier in the automobile transportation, and Trailer car shaft is the major part on the trailer car sedan-chair simultaneously, and it bears heavy duty and alternate load.In the prior art, when component forming is axletree, need the side's of pushing away operation, the side of pushing away finishes under cold conditions, needs huge thrust, and the side of pushing away is very big with the pressure that sliding bearing adopts copper sheathing to bear in the prior art, though the copper sheathing wearability is good, the soft pressure that bears of matter is big inadequately, under huge radial load effect, copper sheathing just deforms, wall thickness reduces, and endoporus increases, and has lost effect, and copper sheathing raw material costliness has increased the production cost of axletree greatly.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of cost the low and durable axletree side of pushing away device.
In order to solve the problems of the technologies described above, the utility model provides a kind of axletree side of pushing away device, comprise the side's of pushing away fixed axis, the described side of pushing away fixed axis be arranged in parallel, form the chamber, the side of pushing away of axial cross section square frame shape, all be socketed with on the described side of the pushing away fixed axis and can hold, hold the inwall that contacts with the described side of pushing away fixed axis and be provided with lubricating layer along the described square shaft that pushes away around the square shaft that pushes away of the described side of pushing away fixed axis rotation.
Preferably, described lubricating layer is for adopting the SF-2 layer of SF-2 material.
Preferably, described SF-2 layer is provided with the cavity volume of a plurality of indents.
Preferably, the described square shaft that pushes away holds and is set to self-lubricating bearing; The lubricating layer of described self-lubricating bearing is set to adopt the SF-2 layer of SF-2 material; Described SF-2 layer is provided with the cavity volume of a plurality of indents.
Implement the utility model, have following beneficial effect:
The internal face of the bearing in the utility model in the axletree side of the pushing away device is provided with lubricating layer, and described lubricating layer is for adopting the SF-2 layer of SF-2 material, described SF-2 layer is provided with the cavity volume of a plurality of indents, added once and can use for a long time behind the oil and needn't always refuel, it is good to have wearability, bearing capacity is strong, and the characteristics of long service life greatly reduce production cost.
Description of drawings
The cross sectional representation of a kind of axletree of Fig. 1 the utility model side of pushing away device;
Fig. 2 is the lubricating layer structural representation of self-lubricating bearing in a kind of axletree of the utility model side of pushing away device.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.
The cross sectional representation of a kind of axletree of Fig. 1 the utility model side of pushing away device comprises the side's of pushing away fixed axis 1 and pushes away square shaft and hold 2 that the described side of pushing away fixed axis 1 be arranged in parallel, forms the chamber, the side of pushing away 3 of axial cross section square frame shape.The described square shaft that pushes away holds 2 and is socketed on the described side of pushing away fixed axis 1 and is the axle center rotational slide along the described side of pushing away fixed axis 1.Hold 2 and be provided with lubricating layer 21 along the described square shaft that pushes away with the inwall that contacts of the described side of pushing away fixed axis 1.
Described lubricating layer 21 is for adopting the SF-2 layer of SF-2 material, and as shown in Figure 2, described SF-2 layer is provided with the cavity volume 211 of a plurality of indents, and described cavity volume 211 can hold oily matter, for the described square shaft that pushes away holds 2 lubrication is provided when the rotational slide.
Need explanation, self-lubricating bearing in the utility model and the above-mentioned square shaft that pushes away hold 2 much the samely at 26S Proteasome Structure and Function, are not described in detail in this.
As from the foregoing, the internal face of the bearing in the utility model in the axletree side of the pushing away device is provided with lubricating layer, and described lubricating layer is for adopting the SF-2 layer of SF-2 material, described SF-2 layer is provided with the cavity volume of a plurality of indents, can hold the lubrication oil material, makes described bearing add once can to use for a long time behind the oil and needn't always refuel, it is good to have wearability, bearing capacity is strong, and the characteristics of long service life greatly reduce production cost.
The above is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
