Description
Technical field
The present invention relates to a kind of cycloidal planetary gear speed reducer, particularly a kind of spacing ring for planetary cycloidal pin gear reducer.The present invention is widely used in the speed reducing machinery in various driving mechanism, as the driving in the fields such as textile printing and dyeing, light industry and food, metallurgical mine, petrochemical industry, lifting transport and engineering machinery and speed reducer.The invention belongs to technical field of mechanical transmission.
Background technique
Cycloidal planetary gear speed reducer adopts cycloidal pin teeth engagement, planetary drive principle, so be usually also referred to as cycloidal planetary gear speed reducer.The whole transmission device of cycloidal planetary gear speed reducer can be divided into input, export and three parts of slowing down.Cycloidal planetary gear speed reducer is equipped with two eccentric bushings of a dislocation 180 ° on input shaft, eccentric bushing is equipped with the roller bearing that two are called pivoted arm, form H mechanism, the center hole of two cycloid wheel is the raceway of rotary arm bearing on eccentric bushing, and be meshed with the pin tooth of one group of annular array on pin gear by cycloid wheel, to form the internal messing reducing gear that tooth difference is a tooth.When input shaft rotates with eccentric bushing, due to the feature of tooth curve in cycloid wheel and by the event of pin gear upper pin gear restriction, the motion of cycloid wheel becomes the plane motion that existing revolution has again rotation, when the positive turn-week of input shaft, eccentric bushing also rotates one week, cycloid wheel turns over a tooth in opposite direction thus is slowed down, relend and help W output mechanism, the low speed spinning motion of cycloid wheel is passed to output shaft by bearing pin, thus obtaining lower output speed, cycloidal planetary gear speed reducer adopts oil lubrication.In cycloidal planetary gear speed reducer, cycloid wheel is wherein important work component, spacer ring is provided with between two cycloid wheel, the quality of spacer ring structure and quality is directly connected to working life and the transmission effect of cycloid wheel, and therefore spacer ring plays a very important role in cycloidal planetary gear speed reducer.The cycloidal planetary gear speed reducer spacer ring of current this structure also exists following defect: (1) wears no resistance, non-refractory, and using effect is poor, and noise is large, and working life is short.Current cycloidal planetary gear speed reducer spacer ring is made up of circular spacer ring body, the both sides end face that spacer ring body and cycloid wheel contact is large-area planar and contacts, namely spacer ring body is solid construction, this structure makes spacer ring both sides end face and cycloid wheel carry out comprehensive engagement, therebetween non lubricant oil, be in dry grinding state, temperature rise between spacer ring and cycloid wheel, the both sides end face of spacer ring is very easily worn, spacer ring wears no resistance, non-refractory, and using effect is poor, noise is large, and working life is short; Spacer ring bulk material adopts cast iron materials in addition, and also make spacer ring conduct heat fast, temperature rise, wears no resistance, and using effect is poor, and noise is large, and working life is short; (2) cost is high, pollution lubricating oil.Existing spacer ring body is that solid construction makes materials'use amount large, not only wastes material, and causes cost greatly to increase; The making material of existing spacer ring body is cast iron materials in addition, and cast iron materials price is high, and this also causes spacer ring cost high; Moreover cast iron materials easily grinds iron ion, also can pollute the lubricant oil in transmission device, lubrication effect and working life that lubricant oil is dirty not only to be caused oily impurity to increase affecting each transmission part in transmission device, and make lubricant oil just need to change once general have more than is needed half a year, sometimes two or three months just needs to change, and this also causes cost high.
People exploring always and studying can make up above-mentioned defect cycloidal planetary gear speed reducer spacer ring to meet the active demand in market, but this technical barrier cannot be solved always.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of structure is simple, wear-resisting, high temperature resistant, noise reduction, long service life, the spacing ring for planetary cycloidal pin gear reducer that energy-conservation, cost is low.
Realizing above-mentioned purpose technological scheme is: a kind of spacing ring for planetary cycloidal pin gear reducer, is made up of circular spacer ring body, the left and right sides end face of described spacer ring body all has annular groove, spacer ring body also has oil-feed gap.
Further, evenly stiffening rib is provided with in described annular groove.
Further, described oil-feed gap is arranged on the ring end face of these both sides, inside and outside of spacer ring.
Further, the making material of described spacer ring body is nylon.
Further, described oil-feed gap has 16 altogether.
After adopting technique scheme, there is a lot of benefit: the present invention changes traditional cycloidal planetary gear speed reducer spacer ring structure, all offers annular groove, spacer ring body also offers oil-feed gap by the left and right sides end face of spacer ring body.Structure of the present invention is simple, wear-resisting, high temperature resistant, noise reduction, long service life, and clean, energy-conservation, cost is low.Be in particular in:
(1) wear resistance is good, high temperature resistant, and using effect is good, noise reduction, long service life.The left and right sides end face of spacer ring body of the present invention all offers annular groove, the both sides end face that spacer ring body of the present invention is contacted with cycloid wheel is small size plane contact, namely spacer ring body is non-solid structure, left and right sides end face and the cycloid wheel of spacer ring body are carried out small size and are contacted, and spacer ring body also offers oil-feed gap, lubricant oil enters in annular groove through oil-feed gap, make, between spacer ring body both sides end face and cycloid wheel, there is lubricant oil, cooling lubrication is played to spacer ring and cycloid wheel, make spacer ring temperature rise low, the both sides end face of spacer ring is not easily worn, spacer ring wear resistance is very good, and it is high temperature resistant, using effect is good, excellent noise reduction effect, noise is low, long service life, the making material of spacer ring body adopts nylon in addition, and nylon thermal expansion coefficient is little, and play effect that is wear-resisting and that suppress temperature to raise, this also makes wear resistance of the present invention good, and using effect is good, and noise is little, long service life.
(2) environment friendly and pollution-free, clean, energy-conservation, cost is low.Spacer ring body of the present invention is that non-solid structure makes materials'use amount fall greatly, saves lot of materials and avoids waste, cost is reduced greatly, very energy-saving and environmental protection; The making material of spacer ring body of the present invention adopts nylon in addition, and nylon material is cheap, and cost of the present invention is reduced; Moreover nylon material can not pollute the lubricant oil in transmission device, environment friendly and pollution-free, lubricant oil is the clean high lubricating effect making each transmission part in transmission device totally, long service life, and oil replacing in a year is once also no problem, this also makes cost greatly reduce.
(3) intensity is high.The present invention owing to being provided with stiffening rib in annular groove, and therefore intensity of the present invention is high, not easily breaks and damages, and this also extends working life of the present invention.
