Description
Technical field
The utility model relates to engineering machinery field, and a kind of creeper undercarriage caterpillar wheel is specifically provided.
Background technology
Creeper undercarriage is one of traveling gear the most frequently used in large-scale engineering machinery (hydraulic excavator, pile driver, revolve and dig brill etc.).In traveling gear, the serviceability of caterpillar wheel directly has influence on traveling gear and the working condition to construction machinery and equipment.
In prior art, caterpillar wheel is mainly made up of wheel body, copper sheathing, wheel shaft and end cap, and wheel body inwall is provided with oil resevoir, and wheel shaft sidewall is milled with penetration type oilway.When caterpillar wheel work, the lubricating oil in oil resevoir enters the space between copper sheathing and wheel shaft by oilway, makes wheel shaft obtain lubrication protection.
The wheel shaft of caterpillar wheel is long, and in order to make also to obtain moderately lubrication protection near the part at wheel shaft two ends, penetration type oilway just must reach certain length, therefore, is just merely able to, with peripheral milling, wheel shaft is carried out to grinding processing in the time of processing and lubrication oil groove.Due to, once can only workpiece of clamping when peripheral milling grinding, and clamping efficiency is low, has a strong impact on the production efficiency of wheel shaft.
The principle of work of peripheral milling: pack workpiece one end into movement folder, put into grinding machine, then withstand the other end of workpiece with tailstock center, in the time unclamping workpiece, emery wheel just can only be allowed to unclamp tailstock center when the going-back position, work-handling is cumbersome, and is once merely able to workpiece of clamping.
The principle of work of centreless grinding: emery wheel High Rotation Speed carries out grinding, guide wheel, with compared with jogging speed rotating Vortex, drives workpiece rotation to do rotary feed.When centerless grinder through feed grinding, realize axial feed by the small skew angle of adjusting guide wheel axis.Centerless grinder is furnished with automatic loading and unloading mechanism, can carry out automatic cycle grinding.
The efficiency of centerless grinder in the time of grinding axis is higher as can be seen here.
Summary of the invention
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of reasonable in design, creeper undercarriage caterpillar wheel that production efficiency is high is provided.
The utility model solves the technical scheme that its technical matters adopts: a kind of creeper undercarriage caterpillar wheel, comprise wheel body, copper sheathing, wheel shaft and end cap, wheel body is socketed in wheel shaft middle part by copper sheathing, the middle part of described wheel body inwall has oil resevoir, described wheel shaft sidewall is milled with oilway, two end caps are separately fixed at wheel shaft two ends, and be tightly connected by float grease seal and wheel body, be characterized in that described oilway is two sectional type oil groove, two sections of oil grooves are linearly symmetrically distributed on wheel shaft sidewall, and between two sections of oil grooves, the width of wheel shaft is less than the width of oil resevoir.
Two sectional type oil groove, that is, in the middle of wheel shaft some milling is illogical, and the logical part of milling is not narrower than the oil resevoir of wheel body.
The middle not logical part bossing of milling can make up the defect of centerless grinding guide wheel width, and it can be processed on centreless grinding, has improved thus production efficiency.
For the ease of oil change more, place, oilway bottom surface plane is vertical with horizontal surface, that is, when wheel shaft is in place, oilway place plane becomes 90o angle with ground.
Rounding off between oilway and wheel shaft, further to improve lubricant effect, avoids scratch copper sheathing to cause leakage of oil.
Creeper undercarriage of the present utility model with caterpillar wheel compared to the prior art, there is following outstanding beneficial effect:
(1) two sectional type oil groove, makes wheel shaft can be good at adapting to centerless grinder, not affecting under the prerequisite of oil lubrication effect, can increase substantially work efficiency;
(2) oilway bottom surface vertically arranges, and more oil change is more convenient.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model creeper undercarriage caterpillar wheel;
Accompanying drawing 2 is structural representations of the caterpillar wheel of creeper undercarriage shown in Fig. 1 wheel shaft;
Accompanying drawing 3 is A-A line section-drawings of wheel shaft in Fig. 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
In the utility model, in the situation that not doing contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings as " upper and lower, left and right "; " inside and outside " refers to inside and outside with respect to the profile of each parts itself.
Provide a most preferred embodiment below:
A kind of creeper undercarriage caterpillar wheel, is mainly made up of wheel body 1, copper sheathing 2, wheel shaft 3, end cap 4 and set pin 5.
Wheel body 1 center is provided with installation through hole, and the middle part that through-hole wall is installed has oil resevoir 6.Wheel body 1 is socketed in wheel shaft 3 middle parts by the copper sheathing 2 being arranged in through hole.Two end caps 4 are fixed on wheel shaft 3 two ends by set pin 5 respectively, and are tightly connected by float grease seal 7 and wheel body.
Wheel shaft 3 sidewalls are milled with two sectional type oil groove.Two sections of oil grooves 8 are linearly symmetrically distributed on wheel shaft 3 sidewalls, and between two sections of oil grooves 8, the width of wheel shaft is less than the width of oil resevoir 6.
Place, the bottom surface plane of two sections of oil grooves 8 is vertical with horizontal surface, and rounding off between two sections of oil grooves 8 and wheel shaft 3.
Above-described embodiment, the just more preferably one of detailed description of the invention of the utility model, the common variation that those skilled in the art carries out within the scope of technical solutions of the utility model and replacement all should be included in protection domain of the present utility model.
