Abstract
The utility model relates to a kind of single-row pulley deep groove ball bearing, comprise outer ring and inner ring, described inner ring is arranged in the internal diameter of outer ring, between described outer ring and inner ring, retainer is installed, retainer is provided with several mounting grooves, is provided with steel ball in mounting groove, and described inner ring has stepped slot, with seal ring sealing between described outer ring and stepped slot, the external diameter of described outer ring along the circumferential direction has a circle pulley groove.The utility model employs pulley and combines together with bearing, bearing can be used as pulley, there is enough thrust load capacity, pulley groove on outer ring may be used on non-slip device, the appearance of vibrations skidding when preventing from operating, and the sealing effect of seal ring is better than the sealing of general bearing.
Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of single-row pulley deep groove ball bearing.
Background technique
Deep groove ball bearing is a type the most common in rolling bearing.The deep groove ball bearing of basic model is by an outer ring, and an inner ring, one group of steel ball and one group of retainer are formed.Deep groove ball bearing type has single-row and biserial two kinds, and deep-groove ball structure also divides sealing and open type two kinds of structures, and open type refers to that bearing is not with sealing configuration, and sealed type deep-groove ball is divided into dust sealing and anti-oil seal.Dust sealing cover material is steel plate punched, only plays and simply prevents dust from entering bearing race.Oilproof is contact oil seal, can effectively stop the lubricating grease in bearing excessive.
On the basis of common deep groove ball bearing, employ pulley to combine together with bearing, bearing can be used as pulley, there is enough thrust load capacity, pulley groove on outer ring may be used on non-slip device, the appearance of vibrations skidding when preventing from operating, and the sealing effect of seal ring is better than the sealing of general bearing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of single-row pulley deep groove ball bearing, employ pulley to combine together with bearing, bearing can be used as pulley, there is enough thrust load capacity, pulley groove on outer ring may be used on non-slip device, the appearance of vibrations skidding when preventing from operating, and the sealing effect of seal ring is better than the sealing of general bearing.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of single-row pulley deep groove ball bearing, comprise outer ring and inner ring, described inner ring is arranged in the internal diameter of outer ring, between described outer ring and inner ring, retainer is installed, retainer is provided with several mounting grooves, is provided with steel ball in mounting groove, and described inner ring both sides have stepped slot, with seal ring sealing between described outer ring and stepped slot, the external diameter of described outer ring along the circumferential direction has a circle pulley groove.
Preferred as one of the present utility model, the both sides of described inner ring all exceed 1.85mm than the both sides of outer ring.
Preferably another kind of as the utility model, described retainer has 7 mounting grooves, steel ball is that stainless steel is made, and its diameter is 3.969mm.
Preferably a kind of as also having of protecting jacket described in the utility model, described seal ring is dual face seals circle.
beneficial effect
The utility model relates to a kind of single-row pulley deep groove ball bearing, compared with common deep groove ball bearing, it use pulley to combine together with bearing, bearing can be used as pulley, there is enough thrust load capacity, be specially adapted to the application of high rigid requirements, in addition, the pulley groove opened at this bearing outer ring place also can be used on non-slip device, can be convenient to again fixation is installed, make it very stable in the running, prevent the appearance shaking skidding, because considering that bearing needs to be used in the higher occasion of limit speed sometimes, therefore during optimal design, nylon cages is adopted to carry out supporting, make bearing temperature rise very little, be convenient to bear axially larger load, increase the bearing life-span operationally, thus extend product service time, finally, compared to biserial pulley deep groove ball bearing, the single-row demand that substantially can meet generally to bearing, so single-row convenient in manufacture, structure is simpler, material is more economized.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
