Abstract
A kind of retainer applied on milling train ball bearing, internal side diameter reveals all the details as taper on the pocket hole for keeping stand and retainer lid, the end face outside of stand and retainer lid is kept respectively symmetrically to mill out multiple conical sockets, conical socket number is identical with pocket hole count, and conical socket is located at the connection hole that stand and retainer lid are kept between two pocket holes.The advantage is that: realizing steel ball guidance retainer first, tapered pocket hole reduces the deflection of steel ball center-diameter, to reduce the deflection of retainer, effectively reduces the friction between retainer internal diameter and lasso rib；And tapered pocket hole plays the role of trapped fuel, oil storage, strengthens lubrication, improves the service life of bearing.The weight for alleviating retainer reduces the deflection of retainer, reduces the friction of retainer Yu lasso rib；In addition the mitigation of retainer weight, reduces expense, has saved cost.
Description
Technical field
The invention belongs to field of bearings, in particular to a kind of retainer applied on milling train ball bearing and the axis using it
It holds.
Background technique
The internal diameter or outer diameter of traditional ball bearing retainer, with lasso lip-guided, direct friction.Large size bearing is kept
Frame itself is heavier, especially milling train ball bearing retainer quick abrasion, causes bearing life to shorten, influences entire production system.
And large size bearing price is higher, and equipment cost is caused to increase, and original retainer has been difficult to meet production requirement, for this
Present situation need to optimize traditional retainer especially for milling train operating condition, be the urgent need for meeting the market demand.
Summary of the invention
The object of the present invention is to provide a kind of retainer applied on milling train ball bearing and using its bearing.The structure
Bearing reduces the deflection of large-scale ball bearing retainer, reduces the abrasion of retainer, enhances lubrication, improves bearing wearability,
The structure retainer effectively extends the service life of bearing.
The technical solution adopted is that:
A kind of retainer applied on milling train ball bearing, including keep stand and retainer lid, it is characterised in that:
Internal side diameter reveals all the details as taper, the outboard end of holding stand and retainer lid on the pocket hole for keeping stand and retainer lid
Face respectively symmetrically mills out multiple conical sockets, and conical socket number is identical with pocket hole count, and conical socket is located between two pocket holes
Keep the connection hole of stand and retainer lid.
A kind of ball bearing applied on milling train, including inner ring, outer ring, retainer and multiple steel balls, it is characterised in that:
Above-mentioned retainer includes keeping stand and retainer lid, and internal side diameter reveals all the details on the pocket hole for keeping stand and retainer lid
For taper, the end face outside of stand and retainer lid is kept respectively symmetrically to mill out multiple conical sockets, conical socket number and pocket
Hole count is identical, and conical socket is located at the connection hole that stand and retainer lid are kept between two pocket holes.
It keeps stand and retainer cover buckle to close setting, is inserted into bolt in the connecting hole for keeping stand and retainer lid,
Rotation sets nut on bolt, and outer ring is set on inner ring, and multiple steel balls are installed in the corresponding pocket hole of retainer, and holding is erected at outer
In the raceway that circle and inner ring are constituted.
The advantage is that:
Pocket hole is done tapered first, close to internal diameter reveal all the details do it is tapered, realize steel ball guidance retainer, tapered pocket hole reduce
The deflection of steel ball center-diameter to reduce the deflection of retainer effectively reduces retainer internal diameter and lasso rib
Between friction；And tapered pocket hole plays the role of trapped fuel, oil storage, strengthens lubrication, improves the service life of bearing.
It keeps the lateral surface of stand and lid respectively to mill out and is located at two pocket holes with point same conical platforms such as ball number, taper platform
Between, the connection hole of stand and retainer lid is kept, taper platform alleviates the weight of retainer, reduces the sinking of retainer
Amount, reduces the friction of retainer Yu lasso rib；In addition the mitigation of retainer weight, reduces expense, has saved cost.
Stand is kept to connect with retainer cover bolt, it is then locked with nut, it is succinct conveniently and using secured.
Due to the change of inner structure form, bearing capacity is improved, realizes specified 10% or more dynamic load growth, it is specified
Diameter, which carries, increases by 15% or more, effectively extends the service life of bearing.
