Abstract
The utility model discloses a kind of rotating pin linkage structure, comprise rotating stand, fixed bearing, bearing pin and the some copper alloy shaft sleeves be sleeved between fixed bearing and bearing pin, described rotating stand is arranged on fixed bearing by bearing pin is rotatable, described rotating stand comprises upper bracket and two undersettings, the step type that in the middle of described bearing pin adopts, high two ends are low, on this upper bracket and undersetting, symmetrical having respectively holds with bearing pin the semi-circular hole matched, described upper bracket and undersetting are sleeved on bearing pin and respectively hold and be bolted and freely rotate relative to fixed bearing and copper alloy shaft sleeve centered by bearing pin.The utility model dismounting is extremely convenient, achieves the quick mounting of bearing pin, decreases and is changeing the damage to bearing pin and copper sheathing in process.
Description
Technical field
The utility model relates to a kind of link field, particularly relates to a kind of rotating pin linkage structure being applicable to mine truck, mine scraper.
Background technique
Rotating pin linkage structure is a kind of force transferring structure realizing relative movement the most conventional in engineering, and it is widely used, and littlely arrives engineering machinery greatly to household articles, ubiquitous.Due to this structure not unified standard, in the design, different type of machines, different designs personnel, the structure designed is of all kinds, wherein general structure as shown in Figure 3, comprise rotating stand a, fixed bearing b, bearing pin c and the copper alloy shaft sleeve d be sleeved between fixed bearing b and bearing pin c, rotating stand a adopts integral structure, bearing pin c adopts cylindrical, during assembling, need first copper alloy shaft sleeve d to be loaded in fixed bearing b, is alignd in the axle center of rotating stand a and copper alloy shaft sleeve d mounting hole again, finally insert bearing pin c, because easily damaged parts is generally be welded on rotating stand a, therefore when changeing, first bearing pin c must be pounded out in rotating stand a and copper alloy shaft sleeve d, just can pull down rotating stand a.No matter be install or dismounting, bearing pin is all larger with the mutual wearing and tearing dynamics of mounting hole on rotating stand and copper alloy shaft sleeve, when bearing pin and each mounting hole coordinate be transition fit time, also can strengthen installation and removal difficulty, be unfavorable for quick assembling, using effect is undesirable.
Model utility content
The purpose of this utility model is to provide a kind of installs, convenient disassembly, rotating pin bearing little to the damage of component when changeing.
This rotating pin linkage structure that the utility model provides, comprise rotating stand, fixed bearing, bearing pin and the some copper alloy shaft sleeves be sleeved between fixed bearing and bearing pin, described rotating stand is arranged on fixed bearing by bearing pin is rotatable, described rotating stand comprises upper bracket and two undersettings, the step type that in the middle of described bearing pin adopts, high two ends are low, on this upper bracket and undersetting, symmetrical having respectively holds with bearing pin the semi-circular hole matched, described upper bracket and undersetting are sleeved on bearing pin and respectively hold and be bolted and freely rotate relative to fixed bearing and copper alloy shaft sleeve centered by bearing pin.
For ensureing the long-term accuracy of the utility model upper bracket and first circular port of undersetting, between on described upper bracket and undersetting, male and fomale(M&F) is adopted to connect.
Distinguish installation direction rapidly for convenience of the utility model, the male and fomale(M&F) of described upper bracket and undersetting adopts dissymmetrical structure.
The utility model cuts open formula structure by rotating stand being designed to second, when changeing with rotating stand connected element, only the bolt between upper and lower bearing need be taken apart, without the need to splitting out bearing pin again, to the loss of matching hole on bearing pin, copper alloy shaft sleeve and fixed bearing when decreasing exchonge step and change, extend working life; Complement each other to form Zhou Yuan by the semi-circular hole on upper and lower bearing, realize automatic centering; And the bearing pin of step type can carry out axial limiting to rotating stand, it is installed firm, reliable.The utility model dismounting is extremely convenient, achieves the quick mounting of bearing pin, decreases and is changeing the damage to bearing pin and copper sheathing in process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that Figure 1A is to partial enlargement decomposition texture schematic diagram.
Fig. 3 is the structural representation of prior art.
Embodiment
As can be seen from Fig. 1 and Fig. 2, this rotating pin linkage structure of the utility model, comprise rotating stand 1, fixed bearing 2, bearing pin 3 and two copper alloy shaft sleeves 4, fixed bearing 2 has a mounting hole 21, the staircase structural model that bearing pin 3 adopts middle high two ends low, copper alloy shaft sleeve 4 is arranged in the mounting hole 21 of fixed bearing 2, bearing pin 3 is sleeved in copper alloy shaft sleeve 4, rotating stand 1 comprises upper bracket 11 and two undersettings 12, on upper bracket 11 and undersetting 12, symmetrical having respectively holds with bearing pin 3 semi-circular hole 13 matched, this upper bracket 11 and undersetting 12 are respectively held cylndrical surface to match by semi-circular hole 13 with bearing pin 3 to be sleeved on bearing pin 3, be bolted between upper bracket 11 and undersetting 12 and drive bearing pin 3 freely to rotate relative to fixed bearing 2 and copper alloy shaft sleeve 4 centered by bearing pin.
As can be seen from Fig. 1 and Fig. 2, a heavy stand 14 is provided with in the both sides, bottom surface of the utility model upper bracket 11, a boss adapted 15 is provided with in the end face both sides of undersetting 12, coordinated by heavy stand 14 and boss 15 between upper bracket 11 with undersetting 12 and realize male and fomale(M&F) and connect, the heavy stand 14 in upper bracket 11 both sides and the boss 15 in undersetting 12 both sides all adopt dissymmetrical structure with the axle center of bearing pin 3.
In working process of the present utility model, first upper bracket 11 can be connected with bolt of serration with undersetting 12, reprocess the semi-circular hole 13 coordinated with bearing pin 3, guarantee the accuracy of matching hole position.
When the utility model is installed, first copper alloy shaft sleeve 4 is loaded fixed bearing 2, reinstall bearing pin 3, then bolt between upper bracket 11 and undersetting 12 is unclamped, circular port semi-circular hole 13 formed aims at each end of bearing pin 3, by the bolt tightening between upper bracket 11 and undersetting 12.
In actual use, generally easily damaged parts is welded on rotating stand 1, therefore when changeing, only the bolt of upper bracket 11 and undersetting 12 need be unclamped, semi-circular hole 13 is aimed at bearing pin 3, then by bolt tightening.
