The roller heavy haul rolling spline pair has large bearing capacity, convenient installment without collision among rollers, small abrasion, low working noise and long service life, which is a rolling spline pair adapted for transferring large moment of torque.
Description
Technical field:
The utility model relates to a kind of rolling spline pair, specifically a kind of roller load-carrying rolling spline pair.
Background technique
Along with the numerical control development of all kinds of equipments, to transmitting the functional part rush of demand that straight line motion again can transmitting torque, especially need can transmitting large torque functional part.Large-scale, heavily loaded, the lightweight equipment of development is one of important trend of equipping now industry development under the prerequisite that does not reduce function of use.Rolling spline pair is applied in the various equipments, as lathe, chemical industry equipment, printing machinery, medical apparatus, light industry or the like, is mainly used to not only transmit straight line motion but also transmitting torque.
At present, traditional is that the rolling spline pair of rolling element exists following shortcoming with the steel ball:
1, rolling spline pair is made up of spline housing 12, splined shaft 11, steel ball 13 and back device 14, sees Fig. 1, and it both can transmit straight line motion, also can transmitting torque, but traditional rolling spline pair is realized carrying and motion by steel ball, and transmitting torque is limited, is not suitable for the transmitting large torque occasion.
2, the design of back device is in spline housing inside in the traditional rolling spline pair, and complex structure is difficult for processing.
3, directly contact between the steel ball, no isolation mounting, in the process of motion, collision mutually between the steel ball, noise is very big, and working life is short.
4, assembling is complicated, is not suitable for industrialization.
Summary of the invention
In order to adapt to of the requirement of equipment industry development to rolling function parts product, overcome problems of the prior art, the purpose of this utility model provides a kind of roller load-carrying rolling spline pair, this rolling spline adjutant bearing mode changes the line contact into by a contact, increase the roller number of bearing load simultaneously, therefore the load of bearing is bigger; And easy to assembly, be adapted to industrialization production.
The purpose of this utility model is achieved through the following technical solutions:
A kind of roller load-carrying rolling spline pair, it is characterized in that: it comprises splined shaft, spline housing, back device, roller, back device and maintainance block, described spline housing is provided with and the suitable internal diameter of the sectional shape of splined shaft, and the roller of spline housing by axial setting is sleeved on the splined shaft and can moves axially along splined shaft; Roller enters raceway again and carries out rolling motion again and again along the raceway that many processes are quenched and precision grinding processes after the end of spline housing enters the back hole by the back device; On the internal diameter of spline housing, be provided with the maintainance block that is used for limiting the roller traffic direction; The back device that is used for roller is turned to is fixed on the two ends of spline housing.
In the utility model,, in the raceway groove of spline housing, be provided with the intubate that is used for limiting the roller traffic direction for guaranteeing the traffic direction of roller.
The utility model is used for avoiding the maintenance chain that bumps between the two adjacent rollers being provided with between roller.Keep chain to be made of plastics, the plastics roller keeps chain that roller is separated, and has avoided the collision between roller and the roller, has reduced operating noise.
Keep the use of chain that the collision between the rolling element is disappeared, the wearing and tearing of rolling element reduce, and can also have a small amount of lubricating grease in keeping chain, so just can realize long-term Maintenance free maintenance, increase the service life.
The utility model changes carrier into roller by steel ball, and bearing mode changes the line contact into by a contact, and the load of bearing is increased greatly; Can also increase simultaneously the roller number of bearing load, further increase the load of bearing.And, the utility model is arranged on the back device at the two ends of spline housing, change the mode that originally the back device is installed in spline housing inside, in the assembling spline, the back device of an end can be installed earlier, then toward raceway the inside dress roller and maintenance chain, the back device of the other end is installed again, has been made things convenient for assembly process, changed the phenomenon that original steel ball can not be filled raceway.The utility model has been set up the plastics roller and has been kept chain, roller is separated, avoided the collision between roller and the roller, reduced operating noise, keep the use of chain that the collision between the rolling element is disappeared simultaneously, the wearing and tearing of rolling element reduce, and can also have a small amount of lubricating grease in keeping chain, so just realize long-term Maintenance free maintenance, prolonged working life.
Compared with prior art, the utility model has the advantages that: 1, bearing capacity is big; 2, easy for installation; 3, absence of collision between roller and the roller, it is little to wear and tear, and has reduced operating noise, has prolonged working life.
