AI Technical Summary
When a hydraulic motor is shut down in an emergency or improperly, the water column in the water pipe flows back and impacts the impeller, causing it to reverse, damaging internal components, affecting the operation of the water pump, resulting in property damage and delays in the rescue process.
The design incorporates a combination of a one-way rotary bearing and a bearing assembly, with a lock to prevent the motor shaft from reversing, ensuring that the hydraulic motor is not damaged when it reverses. This includes the combined design of the oil supply cap, motor housing, motor shaft, and one-way rotary bearing.
This effectively prevents damage to the hydraulic motor due to reverse rotation, ensures the normal operation of the water pump, and avoids property damage and delays in the rescue process.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to hydraulic motor technical field, concretely is a hydraulic motor that can prevent reverse rotation. BACKGROUND
[0002] In order to facilitate operation, the oil drain pipe and the oil return pipe of the hydraulic motor are often combined in the hydraulic drive emergency water pump, and in this case, if the water pump encounters emergency shutdown or non-standard shutdown, the water column in the water pipe will flow back and impact the impeller, driving the hydraulic motor shaft to produce forced reverse rotation, which will damage the internal parts of the hydraulic motor and cause the water pump to be unable to operate, causing property loss or delaying the emergency rescue process, therefore, the utility model provides a hydraulic motor to prevent forced reverse rotation damage to solve the problem. SUMMARY
[0003] The utility model discloses a hydraulic motor that can prevent reverse rotation to solve the problem proposed in the background art.
[0004] To achieve the above object, the utility model discloses a hydraulic motor that can prevent reverse rotation, comprising an oil supply cover, a motor shell and a motor shaft, the inner side of the oil supply cover is provided with a one-way rotating bearing.
[0005] The motor shell is installed on the right side of the oil supply cover, and the right side of the motor shell is provided with a bearing set.
[0006] The motor shaft is installed on the inner side of the bearing set, and the left end of the motor shaft is connected with the one-way rotating bearing.
[0007] Optionally, the right side of the outer side of the oil supply cover is connected with the motor shell through the threaded connection mode.
[0008] Optionally, the right side of the motor shell is an end cover, and one end of the motor shaft penetrates through the end cover and extends to the right side of the outer side of the motor shell.
[0009] The utility model discloses a technical effect and advantage:
[0010] 1, the utility model discloses in the process of using, when the motor shaft is forced to reverse, the lock of one-way rotating bearing falls into the bearing outer ring and locks, so that one-way rotating bearing cannot rotate, so that the water column in the water pipe will not flow back and impact the impeller, and the condition of damaging the internal parts of the hydraulic motor appears. DRAWINGS
[0011] Figure 1 It is the structure schematic drawing of the utility model.
[0012] In the drawing: 1 is the oil supply cover, 2 is the motor shaft, 3 is the bearing set, 4 is the motor shell, 5 is the one-way rotating bearing. DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0014] The utility model provides a kind of hydraulic motor of preventing reverse as shown in Figure 1 As shown in a kind of hydraulic motor of preventing reverse, including oil supply cover 1, the inside of oil supply cover 1 is equipped with one-way rotating bearing 5.
[0015] The motor housing 4 combined with oil supply cover 1, motor housing 4 is installed at the right side of oil supply cover 1, the right side outside oil supply cover 1 is connected with motor housing 4 by screw connection mode, and the right side inside motor housing 4 is equipped with bearing set 3.
[0016] The motor shaft 2 of rotating drive, motor shaft 2 is installed at the inside of bearing set 3, and the left end of motor shaft 2 is connected with one-way rotating bearing 5, and the right side of motor housing 4 is end cover, and one end of motor shaft 2 penetrates end cover and extends to the right side outside motor housing 4.
[0017] The implementation principle of a kind of hydraulic motor of preventing reverse in the embodiment of the application is as follows: motor shaft 2 is fixed by one-way rotating bearing 5 installed on oil supply cover 1 and bearing set 3 in motor housing 4, in normal operation, motor shaft 2 drives water pump to rotate forward, and the thrust generated by water pump is borne by bearing set 3, and the radial force generated by water pump is borne by bearing set 3 and one-way rotating bearing 5.
[0018] When motor shaft 2 is forced to rotate reversely, the lock of one-way rotating bearing 5 falls into bearing outer ring groove and is locked, so that one-way rotating bearing 5 cannot rotate, and the reverse rotation of motor shaft 2 is prevented, and bearing set 3 and one-way rotating bearing 5 jointly bear the impact force of motor shaft 2, when re-operating normally, the lock of one-way rotating bearing 5 is released from bearing outer ring groove, and the bearing can rotate normally, and the hydraulic motor operates normally.
[0019] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
